Ask any question regrading SingleTact sensor!!

[Lisa Cole]

Are these sensors safe for contact with human skin?

[Steven SanchezKeymaster]

In regards to your question. Yes, it safe for contact with human skin provided the subject has no known allergies and it really depends on where you plan to place the sensor as we would never suggest this to be placed into any orifice of the human body.

What is the maximum pressure the sensors can withstand without breaking?

[Charles MacLeod]

3 x the full scale range

[masterarbeitaParticipant]

How can i convert the Sensor Data Readings like (256) to 0,5V automatic or to Force with Arduino ???

in datasheet of this Sensor says that from 256 to 511 ist = from 0,5 to 1,5 V

[Gordon Dobie]

Are the sensors waterproof?

[Charles MacLeod]

The end of the sensors are sealed up to the neck, so the sensing area is splash-proof, but the neck and electronics are not

[Ward Bartels]

What exactly do you mean by the sensing area being splash-proof? Could the sensing area be submerged in water for some time and still work? Could it work in a humid environment?

[Gordon Dobie]

I get an error “Invalid Settings” what is wrong?

[Charles MacLeod]

Please check the electrical connections

[Gordon Dobie]

My Arduino is not showing up in the Arduino IDE after I have plugged it in, any ideas?

[Charles MacLeod]

This is an Arduino issue, the following link provides information about how to configure your Arduino.

[Gordon Dobie]

Does the software work on Windows 10?

[Charles MacLeod]

Yes

[Gordon Dobie]

Is there a Matlab version of the DAQ software?

[Charles MacLeod]

Not yet, but it is on our roadmap

[mickael]

Hello,

I would like to show values of my singletact on the arduino serial monitor but it seems not work…could you please help me ? thanks,

[Arthur]

Did you find an answer to your question ? I have the same problem.
And I tried to contact singetact by 4 differents ways, no answer in one week…

[Barnali Das]

Hello both,
Here is a demo to show SingleTact value on Arduino Serial Monitor. Please find the code from: https://github.com/Barnali-Das/SingleTactArduinoTest.

Hope this is helpful.

Best regards

[KBell]

Can the sensors be trimmed to fit the application size?

[Gordon Dobie]

Yes, but this invalidates the warranty. Care must be taken because if the cut is not clean it may short the two sides of the sensor. Also, cutting the sensor will invalidate any calibration.

[T.Drechsler]

How do I modify the arduino code (or timer1) to slow the samplng rate?
Default
timeStamp_ = 0;
startTimer1(100); //Timer for timestamp (=~100Hz sampling)

startTimer1(10) =~10Hz sampling

but all aother values for startTimer(x) == much faster sampling rate

[Gordon Dobie]

Please ask the ArduinoTimer author – https://github.com/carlosrafaelgn/ArduinoTimer

[Michele Quattrone]

Hello, how much the sensor + electronics will consume if i need 1 force measure per hour? It is suitable for continous force measurement?
Best regards,
Michele

[Gordon Dobie]

Gordon Dobie
From memory the sensor and electronics draws about 3mA per hour. This is constant and not effected by sample rate and >50Hz can easily be achieved with the sample App (custom code could be much faster). Given the very low sample frequency, you may wish to turn off the sensor between measurements, this could be achieved with some custom electronics turning on/off the Vcc line

[Michele Quattrone]

thanks Gordon,
the next question is: how much time is needed to power up the electronics and do a reliable force measure? Because i have a very small battery space and I need to compute the autonomy of my device.

[Michele Quattrone]

…other small clarification: when you say 3mAh, you intend using 12V constant supply?

[masterarbeitaParticipant]

hey,

How can i convert the Sensor Data Readings like (256) to 0,5V automatic in Arduino or to Force ???

for example i need to know which Force i load on the Sensor ( wenn i load 1N i want to know if the Sensor show me 1N too )

thanks

[vulawoffice.comParticipant]

Can this sensors be used to measure the pression while running ?

[Martyn]

Could you clarify what exactly you mean by “running”?

[Ping Tsui]

We bought these sensor and use it measure the pressure. Can we use your GUI to display multi-sensor pressure measurement at same time.

When I press “update baseline”, the flash of silicon logic MCU broad is corrupted, How can I fix it.

Thanks

[Tim]

Could you comment on the performance of these sensors when compared to a cheap force sensitive resistor? I understand the capacitance based system is more accurate but would appreciate some feedback.

[Radu]

I have purchased a 100 N calibrated sensor, 8 mm diameter. Can I connect a 10 N sensor to the same electronic interface?
Thank you!

[Barnali]

The sensor and electronics have been calibrated as a matched pair. In order to maintain calibration these components should not be combined with other sensor.

[Radu]

Ok, I understand the calibration issue, but I’ll calibrate the sensor myself. I just wanted to know if the 10 N sensor and electronics are compatible.

[Barnali]

Yes. If you want to calibrate that electronics with 10N sensor then you will break existing calibration with 100N sensor.

[Jonathan]

I have 12 sensors and majority of them, I am getting inconstant readings. I recorded the sensor values, both raw and filtered while the sensors are free in the air(no force applied). For the worse sensor, I am getting a sensor reading that goes from -8 to 6 without filter and -4 to 4 with a low pass filter. There is one sensor out of the 12 that performs extremely well. It pretty much stays between 5 and 6.

I have tried switching the board and sensor between the worse and the best. It seems like the problems follows the board.

I have included an image showing the low pass filtered outputs of 4 sensors.

[Jonathan]

No solutions?

[Barnali]

Could you please tell me about the types of sensors(Calibrated or Standard)?

[invalid settings after doing some changes in the .net program]

I have some issues regarding the official application PC executable. When I tried at the first time it works perfectly but when I change a simple thing in the .net program I ‘ve got an invalid settings.

[Barnali]

Could you please check the sensor if it is connected upside down? Also, check the Port selection between Arduino and your computer.

[Alex]

I did all of these, it does not work. I bought 2 set of the sensors, the other one works fine, but for one other it happens exactly like above. The sensor is working well if I use with other I2C board, but when I plug back to the other I2C board the program is not running.

[Leonardo]

Hi!
I just would like to know if it would be possible to know the type of circuit you are using to calibrate/condition the sensor in order to read it.
Thanks

[Barnali]

For SingleTact sensor, we calibrate using uniform pressure over the entire area of the sensor using a PU membrane.

[wallardyceParticipant]

the connectors for the sensor to interface board are very fragile (esp the clip that holds it in) I just had to order two more boards

[g1]

Hi, I would like to use your calibrated sensor for a personal project with an arduino board.
This project involves the use of a mid-size tft lcd touch screen (4.3″) , and since this display require a more powerful board than the arduino UNO ( ad ex. the MEGA 2560) I wonder if your software / drivers works with this board too without a lot of modifications in the code.
Do you have some suggestions about it?

[Barnali]

Our demo software only work with Arduino UNO, if you want to use other board, you have to develop your own Arduino code or PC software.
You will find sample application code for your reference in this link, https://github.com/SingleTact

[Mark Hester]

Hi
Does anyone know how to set up multiple sensors on the single 12c bus using arduino?
I am using a self-written programme in Processing to display the sensor values instead of the Windows DAQ software provided.
But I’m a bit of a newbie with i2c stuff. Is there a piece of arduino code I can use to modify the address of each sensor I have bought?

[Barnali]

Connecting multiple SingleTact sensors with Arduino using I2C:
SingleTact sensors are readable using I2C communication and sample code with Arduino is available from https://github.com/SingleTact/StandaloneArduino.

Multiple sensors can be connected over I2C bus, by adding all SDA and SCL lines together (standard I2C arrangement). However, prior to physical connection, individual sensor address needs to be set with a number between 4-127 using our data acquisition (DAQ) software. Finally the above Arduino code needs to be modified (the ‘loop()’ function) to read various sensors in a round robin fashion.

[AntonParticipant]

I bought 2 sensors with boards and connected them via I2C to arduino UNO/ELEGOO board.

The sensors works fine, when only one is connected, but when there is 2, the example code SingleTactMultiSensorDemo is not working.

I have changed the board I2C address via the .Net application. so one is 0x04, and other is 0x05.

in short readDataFromSensor(short address) only 5 bytes are received for the first request.
If this error is ignored, the app freezes on Wire.endTransmission()

[Viviane]

Hello,

I have the 8mm 100N calibrated sensors. However, the electronics is too close to the sensor for my application. Thus, I am trying to find the connector jumper (the one between the sensor and the provided electronic board) to make an extension by myself.
Could you give the name and part number of this part please?

Thank you for your help

Hello,

Has anyone been successful running I2C acquisition in MATLAB via Arduino?

MATLABs Arduino functionality should let me find attached I2C addresses via scanI2Cbus, but returns an empty array of addresses.

Thank you,

[Lee Felsenstein]

I am working on a sensitive detector for use by handicapped individuals. I would like to know the sensitivity of the 8S-1N sensor in terms of dC/dF. If the response is nonlinear I would like to know the maximum and minimum values for this slope.

[Barnali]

Please find the dC value from our datasheet (https://www.singletact.com/SingleTact_Datasheet.pdf). You can also find change in force (dF) values which is referred as Full Scale Range (FSR).
We would not expect the slope in calibrated sensors to be more than 20% non linear.

Hope these answered your question.

[Lee Felsenstein]

I mistakenly gave a misspelled email address – the correct address is lee@fonlyinstitute.com. If you responded to my inquiry by email ???I request you try again with the correct address.

[Ali Rafie Ravandi]

Hi,

I have purchased the 1N sensor and I love it. However, I look at the graph that and the outout values I see are just numbers that do not make sense a lot. I need to get my output in Newton so I can change it to mmHg. Can anyone please help me.

[Barnali]

If you export values of your graph to a .csv file you can obtained the same output which is given in PSI (Pound per square inch) unit. You can use these values to convert to your chosen unit.

[Ali Rafie Ravandi]

actually what you are saying is wrong. I have put the sensor under a blood pressure cuff and for example for 27mmHg it reads about 90 in the graph. But 1 PSI =51 mmHG, so the reading is not in PSI. It would be great if anyone could help me to understand what is the output unit.

[Barnali]

Force in N = ( Output/512 ) * full scale range in N (Same applies in lb (US unit))
Pressure = Force / Sensor area
You will find more information at the following link https://www.singletact.com/choosing-a-singletact/

[Amelia]

I am using the singletact with an i2c connection to raspberry pi zero and having an issue with my output. It gives me very frequent sharp negative peaks both with and without any applied load. Any thoughts? Thanks!

[Barnali Das]

I’d suggest to increase the buffer size for bad frames. Its on line 284 of the Raspberry-Pi program available from https://github.com/SingleTact/RaspberryPiDemo/blob/master/pps-singletact.py

[Danielle]

Can this sensor be soldered at the contacts?

[Barnali]

You can try but we can not guarantee the performance.

[Irina]

Hello, is the 400KHz I2C supported? The datasheet only lists 100KHZ but the manual pg. 6 lists both 100KHz and 400KHz. If it is, are there any configurations changes I need to make from 100KHz? Thank you!

[Gordon Dobie]

100kHz is the only mode officially supported.

You should be able to get close to 400Hz, but the electronics process runs at a reduced clock rate to reduce power consumption and may be slow to respond.

[Dmitri DK Yoon]

I have an intel joule developer kit.
However, I try to operate the sensor through the i2c bus, but it is not recognized by i2cdetect. I think it’s probably because the clock is 100khz. Other i2c devices are recognized correctly.
Please let me know how I can solve this problem.

[Barnali Das]

We have tested the sensor in Arduino UNO and Raspberry Pi board. We don’t have any experimental data with Intel joule developer kit.

[Prasad]

We have 8mm dia, 1N/0.22lb force calibrated sensor with electronics and additional 15mm dia 4.5N/ force standard sensor. Calibrated sensor (8mm) works fine with Arduino board & PC executable setup but the same setup with just sensor replaced by standard (15mm) sensor doesn’t show any reading on graph.
1. Is it okay just to replace calibrated 8mm sensor with standard 15mm or do I need to purchase calibrated 15mm hardware?
2. Is it possible to update calibration for 15mm to make it work with our current setup? If yes, where can I get the information about it?

[Barnali Das]

The following link will help you to understand the difference between a standard sensor and calibrated sensor: https://www.singletact.com/choosing-a-singletact/

For the Calibrated sensor, the sensor and the electronics have been calibrated as a matched pair. In order to maintain calibration these two components should not be swapped with other SingleTact components. This is due to the calibration data is stored in the electronics’ on-board flash memory.

For the Standard sensor you need to buy the electronics separately.

[Cheonyu]

I want to return my boards to factory reset. Anyone have a way
If you know, I want you to let me know what I should do.

[Gordon]

Hi,

Firstly, why do you wish to reset them? It would be useful for us to understand what went wrong.

Unfortunately, the calibrated sensors can’t be reset.

If you have a standard sensor, most settings can be reset over the Arduino. Let me know the type of sensor (size and force level) and I will post the defaults.

Thanks, Gordon

[Cheonyu]

Hi,

My model name is CS-450N(15mm diameter, 450N/100lb force)
I want to change it to the default setting, because when I first got the item,
It seems like I accidentally sent strange values while testing to get I2C communication to and from the sensor.
Newly purchased sensors can now send and receive values correctly, but older sensors do not work properly.

Thanks,
Cheonyu

[Barnali]

Could you please tell us more on what exactly did you do with I2C communication. If it is related to I2C address on the sensor, 0x04 is the default and you will be able to read from there. Perhaps direct Arduino code will help you to debug more.

Please have a look here: https://github.com/SingleTact/StandaloneArduino

[soham]

hi,

do the sensors work with line/point loads or do the loads have to be uniformly distributed ?

[Barnali Das]

Loads have to be uniformly distributed over the sensor head.

[Soham]

Hi,

Is the single tact force sensor linear in its application?

Thanks
Soham.

[Barnali Das]

Yes, the SingleTact sensor output is linear. For more information please look at the following links https://www.singletact.com/choosing-a-singletact/ and https://www.singletact.com/SingleTact_Datasheet.pdf

Hi,

I would like to know if the 15mm diameter, 45N/10lb force sensor can works for negative pressure detection or juste for the valid range.

Thanks

Hi,

Any info on maximum cycles of Singletact sensor used in cyclic axial load testing?

Thanks.

[brian.peaveyParticipant]

I need to develop a device with multiple (~20) sensors, but do not have the space for multiple interface boards. Is it possible to drive multiple sensors from a single board? Or is it possible to get the code that runs on the interface board so that I could modify it to run on our own board which is capable of interfacing to multiple sensors?
Thanks…

[Barnali Das]

Unfortunately, it is not possible to connect multiple sensors with one electronics. We are also unable to provide design details/code for the electronics board. However, it is possible to arrange something if you need a bespoke solution. Please let us know.

The alternate route is using multiple electronics and I2C arrangement. Sample codes are available here: https://github.com/SingleTact/StandaloneArduino/blob/master/SingleTactMultiSensorDemo.ino

[Viviane]

Hello,

I’ve noticed a weird behavior (to me). When I hover my hand over the sensor (or around) the data are increasing by a lot (more than the noise) and when I remove it, it goes back down. Here’s an example :

Can someone explain to me this behavior? I do not understand how my body can interfere. And I am concerned about my application. I need to be in contact with the skin, are my data false because of this interference?

Thank you

– it’s not linked to the computer, I’ve tested this with different computers and at different distances from it.
– The data are not filtered in any way (as you can see…)

[William]

It appears you’re looking at temperature variance.

[Rahul]

Hi All,

Sesnor : calibrated sensor 15mm diameter, 450N/100lb force

I wanted to increase the length of the adhesive silicon so as to fit my application. Is it possible to increase the length of the sensor tail ?. I want to increase it to 5 inch.

Regards
Rahul

[Barnali Das]

Yes, it is possible to increase the length but, it may reduce the sensor performance.
PS: PPS offers custom sensors.

[abhilashverma025Participant]

Hi
I am working on project in which measurement of force generated by abdominal respiratory cycle is measure that so I am planning to use this capacitive sensor but I was having some doubt
1.Can we get customize manufacturing for water proof sensor and the sensor should be in long strip size with one electronic connection which will attach to the surface of acrylic sheet of dimension 70mmX30mm
2.or second procedure can be using multiple sensors but how to acquire data from multiple sensors and give feed back to the controller to take action for controlling other peripheral.
3.how much time require for customize manufacturing and shipping to India and what is the procedure for customize manufacturing?
4.Do we get same sensor performance in customize manufacturing?
5.do we get customize sensor calibrated or uncalibrated?
please reply thank you

[William]

You should email the company directly.
They are willing to customize sensors, but that brings up the cost.
As stated on here, the sensor is splash resistant at the head.
The body is not splash resistant.

Multiple sensors are possible, but I can’t find any documentation.
I’ve been able to use multiple sensors by having each one with their own Arduino and instance of the software running.

[abhilash verma]

Hi William,
thank you for the reply.So if you are using multiple Arduino for multiple sensors then how you able to synchronize them together?
Do you find the problem of the sensor is very sensitive to noise? as Viviane mention above in video and if it was there how you overcome it?
I found out they are going to launch software for multiple sensors but they didn’t mention time.
eagerly waiting for your response
Regards
Abhilash Verma

[Barnali Das]

Hi Abhilash,
>> Do you find the problem of the sensor is very sensitive to noise? as Viviane mention above in video and if it was there how you overcome it?
This is due to slight temperature cross-sensitivity. As per the datasheet, you will see about 0.2 % FSR error per degree C.

>> Multiple sensors:
Currently, this is not available openly. However, we can provide support if you email SingleTact support.

[abhilash verma]

Hi Barnali,
Thank you for the reply, I didn’t find but before purchasing I wanted to clear.
– I need 4 sensors which will give single feedback output to the motor to control the rotation.how can it be possible with singletact ?
– do I need any filter to remove noise?
– I talked to singletact system’s Indian distributor so he was asking us to order minimum qty 10(no) due to financial reason I can’t so max I can order is 6 qty. so how should I order sensor with circuitry? what is the final cost to deliver in Chennai 600036 India?
eagerly waiting for your response
Regards
Abhilash Verma

[Barnali Das]

Hi Abhilash,
— While we have not tested any set up like you mentioned, we can not comment. However, with multiple sensors connected to single Arduino in a Daisy chain fashion, you will be able to receive individual sensor data sequentially. You can then decide to write your control algorithm. For the sample code on multiple singletact connections please email our support team (info@singletact.com).

— The requirement for the filter depends on the noise you get (which is again based on the temperature variation in your work set up). We believe the sensor performance is very robust and hence we can not comment on the usage of the filter.

— You can order through our website where after a couple of stages it will show the cost of delivery.

Hope this is helpful. Do not hesitate to contact again if you need more information.

[abhilash verma]

Hi Barnali
Thank you for the reply, I will consider your suggestions

Abhilash

[James]

In my application I am looking for an event of pressure reduction, so the sensor remains at near max pressure for long periods. Similar to the case of a sensor being in a pressurized tire. When the tire is punctured the pressure drop will be measured.

Question 1. If the sensor is at max pressure for a long time (months/years) can I expect sensor drift, and if so, then by how much?

Question 2. I understand the sensor is currently not waterproof. Can it be thinly coated with silicon or similar without seriously affecting the sensor output? Has anyone tried this?

Thanks

[Barnali Das]

The answer to question 1:

Drift related information is available from the datasheet (Page 2): https://www.singletact.com/SingleTact_Datasheet.pdf

[James Tallent]

The document states: Drift < 2% per logarithmic time scale
What is the time unit? seconds, hours, days, years?

[Barnali Das]

It is in second.

[James]

If the pressure on the sensor is greater than the sensor pressure rating will it damage the sensor?

[Barnali Das]

Sensor over pressure should be limited to less than 3x FSR (Full Scale Range) to avoid damaging the sensor.
Please refer our manual (page 7, Section 2.2) https://www.singletact.com/SingleTact_Manual.pdf

[Varun]

Can I operate the sensor while it is folded in half? That is, can I fold it and place it between two surfaces?

[Barnali]

The measurement is accurate when pressure is applied uniformly to the entire sensor head. For more information https://www.singletact.com/choosing-a-singletact/

[Michael Mathew]

Hi,

The data sheet doesn’t show the correspondences of the three pins of the singletact transducer.

Could you please tell me what the three pins are?

Best,

Michael Mathew

[Chris Barnhart]

It appears that the calibrated sensors auto-zero themselves at power on. Unfortunately, field calibration isn’t need since the sensors are loaded at that time.

How can this be removed or possibly there is an offset in the registers that I can subtract from the reading?

Also, for a calibrated sensor, what is the relationship between the value read and the pressure?

Chris

[Barnali]

1. Unfortunately, we don’t offer this, but the baseline used is shown in the sample app. This may be helpful for your calculation.
It is also in the resisters – please refer the manual.

Also note that sensors response can go down to -255, so you may see a negative response.

2. The value read and pressure calculations can be done using the relation below: 511 = the sensors full scale range, i.e. 1N if it is a CS8-1N

[Chris Barnhart]

Barnali,

Regarding your answer on Nov 22 – it unfortunately did not clarify the situation. I have reviewed the documentation already and is why I asked for help. The only sample application I know of is the Arduino source code and it is not there.

The documentation does not actually document behavior of registers, it only provides their name in a table – thus I would be guessing. Possibly there is a more detailed mantual that I’m not aware of. Please send it to me.

Finally, immediatly after poweron our CDCs read ~255 when unloaded, so based answer #2, that would suggest that unloaded the force on our 45N sensor is 22.5N.

1) Specifically which register address(es) is needed to discover the offset being used? How is this value turned into k_offset (below.)

2) I need an equation to transform the value that is read from the CDC registors in a calibrated force – in Newtons. If the response is linear I would expect Force_relative = k_slope (CDC_value + k_zero). I need to know k_slope and k_zero.

We’re after absolute force, so there would be an additional term related to the auto-zero at poweron – which is my first question. That equation would likely be : Force_absolute = k_slope * (CDC_value + k_zero + k_offset).

I suspect k_zero is 255, but don’t know that and we’re trying to perform science so guessing is not an option.

The sensors I have purchased are the 45N calibrated mode.

Thank you,
Chris

[Chris Barnhart]

We’re working many calibrated sensors in a single prototype. Is it necessary to keep the sensor with the CDC electronics that came with the sensor? (Or can calibrated electronics be used with any sensor?)
Chris

[Barnali]

It is necessary to keep the sensor-electronics pairing for the calibrated sensor.

[sridhar]

Hi Singletact team,
We are using the single tact sensor and interface card board with an arduino Uno. We seem to have connected the sensor and board to the Uno correctly but we keep getting “invalid settings” error. The troubleshooting says check pin configuration and follow the example in the manual. we did and still get the error. we connected the sensor and the interface card board to a multimeter and the sensor seems to be fine. Can you help elaborate on what you meant by check pin configuration and help us debug this issue?

regards
Sri

[Barnali]

We suggest following checklist:
1. Does the Arduino sample app display the sensor output properly?
2. Is it just the SingleTactDemo windows app that doesn’t work (fails with ‘Invalid settings’)?
3. Does Windows Device Manager show the Arduino as a COM port?

Additionally, please follow instructions in the manual (Section 4.2)
https://www.singletact.com/SingleTact_Manual.pdf

when I right click on the singletact window and click on set scale to default I can see the blue line stay in one line 10.6.

thanks.

[Barnali Das]

Could you please make sure that the Arduino IDE is closed before you connect to our software?

We also suggest some other checks which will help us to debug further:
1. Which version of Windows are they running? (7, 8, 8.1, 10? 32- or 64-bit?)
2. Which language is Windows displaying? (English, Chinese etc.)
3. How many COM ports show up in Device Manager? What’s the highest COM number?

[Hen Toledano]

Hello.
yes, Arduino software was closed during test.
1. Windows 10 64 bit.
2. English version of windows 10.
3. COM4 IS Arduino COM port, how can I see numbers of ports?

Thank you.

Hi,

I’ve been using the 8mm sensors in 1g experimental modelling between a foundation and the soil. I’m also trying to use the sensors in the same model at a high g level (50g) but I’m having issues with the sensors responding at higher g levels. Can you recommend a way to increase the strength of the neck so that does not influence the output.
Also would plastidip be safe to use on the electronics and neck of the sensor to avoid water damage?
Thank you,
Rose

[Barnali Das]

The minimum and maximum pressure including resolution are available from out datasheet: https://www.singletact.com/SingleTact_Datasheet.pdf.

>>Can you recommend a way to increase the strength of the neck so that does not influence the output.
I’m not entirely sure about the question here. Could let us know the experimental set up (perhaps a sketch)?

>> Also would plastidip be safe to use on the electronics and neck of the sensor to avoid water damage?
Our sensors are not waterproof and unfortunately, we can not comment on the performance on the use of other materials like plastidip. However, we offer custom-made waterproof sensors.

Hey guys!
I’m currently working on a school project and one part of the project is to measure the flowrate of granular material. How do I change the sensitivity of the sensor to be able to pick up a grain that weights about 17 mg

[Sagar]

Hello,

I am using Arduino code for receiving data from Single tact Sensor.
I am always getting byte 132(Sensor output in MSb) = 0x4C and byte 133 as 0xCE.
I am able to read every register properly.

So Do I have to write anything on the control byte?

The analog pins work perfect so the sensor is working.

Thanks
Sagar

[Barnali]

I suggest to use our sample Arduino code to read the sensor values: https://github.com/SingleTact/StandaloneArduino/blob/master/SingleTactDemo.ino

[A. Schmidt]

Hey SingleTact Team,

do you issue a corresponding certificate for your sensor CS15-450N? Is it included in the delivery?

Why is the sensor CS15-450N not available at Amazon.

Thanks.
A. Schmidt

[Logan]

Hello,

I recently purchased the SingleTact Force Sensor – S15-450N for a school project. Can I get some help figuring out how to boost the sensitivity of the sensor for forces under a pound?

Thanks,
Logan

[Barnali]

Please refer our datasheet https://www.singletact.com/SingleTact_Datasheet.pdf for the resolution of our sensors. Please note that the sensor needs uniform pressure over the entire sensor head.
You can explore our calibrated sensor range for more accurate result (https://www.singletact.com/choosing-a-singletact/).

[Martin]

Hello,

We recently purchased 8 CS8-10N sensors. Upon testing the 8 sensors we found that each sensor consistently reads the same value but the value differs significantly between sensors. We are using a calibrated weight of 200g and the readings vary between 160g and 353g. All sensors show 0g when there is no load on them. Does anyone have any idea why there’s such a big variation? According to the datasheet I was expecting to be within 10g of the actual value.

Thank you,

Martin

[Barnali]

Could you please check the following:

1. Our sensors measure correctly when pressure is uniformly given on the entire area of the sensor head. Could you please make sure that your load on the sensor follows this?
2. As you have calibrated sensors, you need to make sure that the sensors were not swapped with the electronics at all.

[Martin]

Hi Barnali,

Thank you for the reply.

1. The load is about 80-90% distributed across the surface area. We are balancing the 200g weight on a socket head screw (https://www.mcmaster.com/#93615a350/=1d5glrz). But even if it wasn’t, we are using the same setup for all sensors so shouldn’t they all give the same value (even it’s the wrong one)?

2. Two of them may have been swapped with each other but the other 6 I am confident that they weren’t. Out of curiosity; if I switch sensors and boards for two component then switch them back to their right pair are they going to work properly or does the switching damage the sensors/boards?

Thank you,

Martin

[Barnali]

1. Could you please send us photo(s) of your experimental setup? This will help us understanding the problem.
2. It should not be a problem.

Does anyone have any recommendations for mounting the i2c boards? I am working with a rounded surface but can make it flat if need be. Need a connection as strong as glue would hold. Thanks

[Barnali]

Double sided tape should be ok to stick to a flat surface. A very thin tape is preferable, so that it does not interfere with sensor performance.

[Mark Wylam, M.D.]

Hi Singletact team,
We are using the 4 singletact sensors and interface board with an arduino Uno. 2 sensors work well and we can change the address and they continue to work (currently 0x07 and 0x08). The other 2 sensors keep getting “invalid settings” error. We too have checked pin configuration and follow the example in the manual without succes. We even connected the Arduino with each interface board and sensor and ran the SingleTactAddessChange.ino We connected the sensor and the interface card board to a multimeter and the sensor seems to be fine.

Running Windows 10, 32 bit operating system, x64 based processor.

BTW, I think the sensors now giving “invalid settings” did work until we individually tested the other 2 sensors.

Thank you,

Mark E. Wylam, M.D.

Update. Indeed the analog output is no longer working. Reading out 0.0 volts on the analog output pin. Perhaps the arduino is corrupted the interface board and it needs reprogrammed??

[aldyandra.hami.senoParticipant]

Dear SingleTact,

I would like to know if this sensor can measure dynamic forces from impact with duration around 1ms. The specifications for the 450N sensor says the analog response time is < 1ms which does not give a clear indication as to whether this is possible or not.

Thank you,

[Keshav Bimbraw]

I am trying to use the 15mm diameter, 450N/100lb calibrated force sensor with an Arduino Mega. I am facing problems running it both on standalone and the demo module modes. For the former, the only data I get is -1. For the latter case, the app pops up invalid settings when I specify the com port. I am using a Windows 10 system.

I also made an edit in the original code, like putting this statement in the short readDataFromSensor(short address) loop:
byte i2cAddress = 0x04; // Slave address (SingleTact), default 0x04

since
Wire.requestFrom(i2cAddress, i2cPacketLength);//require 6 bytes from slave
was giving me an error.

Before making this change, I couldn’t run the code. Please help.

[Barnali]

If you receive -1 reading from the sensor that signifies there is either
a) communication issues between your computer and Arduino or
b) Arduino cannot communicate with the sensor using I2C.

Could you please check these connections separately to debug the issue?

[V Fortoul]

Hello,

I’m working with the S15-4.5N singleTact sensor and the SingleTactDemo software.
When I put 230g on the sensor area the displayed digital ouput is about 520 (more thant the expected FS : 450g –> 512).
Is it due to the Reference Gain of 2 (the scale factor is 1)?
I can not modify this Gain so does it mean that the scale factor must be 2 to have FS = 512 = 450g?
Thanks in advance

[Barnali]

We suggest using the default settings (see below)

Reference gain: 01 (2x)
Scale factor: 300 (3.00)

[yousefhakim2Participant]

Hello,

I have few questions about the SingleTact sensors.
1) The SingleTact Demo Arduino code appears to output data in bits or psi. I am wondering whether I can collect data in Newtons.
2) There is a sample code for using 2 sensors. I am wondering about how I can modify the code to use 3 sensors at a time.
3) Can I use a standard sensor with a calibrated I2C board, since these are the only board sold here? Also, from where can I buy these I2C boards separately, without the jumper wires?
4) The calibration curve for the standard sensors is not linear. When I use the standard sensors, is a polynomial curve used to provide data? That is, I want to know whether a polynomial curve or a linear fit is used to provide data from the standard sensors, so that I can determine whether the data from the standard sensor are accurate.
Thank you

[Barnali]

I believe we have answered your questions through email.

[Andy]

I am using your standard (not calibrated) 1N 8mm sensors connected through the electronics board using the analog output mode to a LabJack U3-LV with USB to custom software running on a PC. The intention is to use these to measure pressure on various locations on the human body in motion.
I am having stability issues with the analog output being dramatically influenced by both applied pressure and flexing at the sensor connection point on the electronics board. Even slight flexing or pressure at this point can result in a reading of 10-20gF (100gF full scale).
Any suggestions? I have tried mechanically stabilizing the connection point with some success, but I still have the issue with any applied pressure.
Happy to provide additional information of photos if that would be helpful.
Thanks.

[Barnali]

Normally you need to place the sensor on a flat surface and put load from the top.
In addition could you please provide me with some pictures of your setup and output result to understand in a better way? You can send the pictures in this email address info@singletact.com

[Yousef Hakim]

Hello,

I am using the 8 mm, 100 N calibrated sensors. I have few questions about the sensors.
1) When I use the Arduino standalone SingleTactDemo code, I get readings of ~ 255 PSI without having a load or pressure on the sensor. Is there something wrong with the code, or do I need to change something in the code?
2) I want to get the data in Newton using the Arduino standalone SingleTactDemo code. To do this, I need to divide by 512 and multiply by 100 N. However, the data type for the data is “short” in the code. If I change it to “float” to make the calculations in the code, will this be fine, or will it affect the communication with the I2C board since “float” data are 4 bytes, whereas “short” data are 2 bytes.
3) When I use the SingleTactDemo.exe software and use the equation below to convert to Newton after exporting the data, I get 0-2 N readings without having a load on the sensor. Is there something wrong with the sensor?
Equation: Force = (PSI Output/512) * 100 N

Thank you

[Barnali]

Q1) 255 reading at zero load is fine. For details please refer to the manual (section 2.5): https://www.singletact.com/SingleTact_Manual.pdf
Q2) Once you receive the data in 2 bytes, you can typecast to float for further calculation.
Q3) Please follow our FAQ (Second from the last) for further information:

[Frank]

Hi,
I have two questions:

1. I want to put a fixture (for example a metal disc or plastic puck) to distribute the load on the sensing area. The Sensor will be on mounted on a gripper so the fixture has to stick to the sensor. Would you recommend to use glue for the fixture? Or maybe double tape? I’m not sure if this will have a negative impact on the accuracy or even destroy the sensing area.

2. Is it possible to connect 4 sensors to an Ardiuno and get the data of each sensor separately?

Kind regards

Frank

[Rory Hampson]

Hi Frank,

1)
3M 300LSE Double Sided Tape is recommended for fixing the sensors to such materials.
Make sure the tape does not fold around to the other side of the sensor as this can impair accuracy, best way is to cut the tape to the correct size before fixing the sensor.

2)
It is certainly possible to connect multiple sensors to an Arduino, or any other microcontroller. It is simply a matter of giving each sensor its own unique I2C address and polling them one by one. Naturally, reading from multiple sensors in the analogue domain is simply a matter of connecting each sensor to a separate analogue input.
A detailed explanation of using multiple sensors digitally is found on the ST_AN_002 app note:
https://www.singletact.com/ST_AN_002_MultipleSensors.pdf

I hope this helped.

I am trying to communicate with the Interface Board NOT using an Arduino. I read registers 128-133 and see 128-129 increasing but registers 130-133 always read FF DF EF F7. Many registers in the 1-15 range read high numbers (EF to FF). Analog output works fine. Am I getting incorrect readings from the registers, or must registers be set to something to make the digital output work? We hope to use this sensor on a new product. Thanks for any assistance.

Hi, I am writing to asking for technical support. I am currently doing a project using matlab/simulink and I am hoping to collect and process data on it. It’d be great if you guys can help me about it.

[JIANG PING]

Hi, just add on to my last post. I am currently doing a project using matlab/simulink and I am hoping to collect and process data on it, with the path: sensor—Arduino uno—PC. I have matlab support package and simulink support package for Arduino, but seems hard to translate the code from Arduino IDE to matlab. or is there an easy way to access readable data?

[Rory Hampson]

Jiang Ping,

I hope your project is going well.

There are several ways to interface an Arduino to Matlab.

1) use the Matlab Arduino support package and use the read() / write() functions to interface with the SingleTact sensor. Remember to set a suitable delay in the Matlab script as Matlab can process much faster than an Arduino can.

2) Rewrite the SingleTact stand alone Arduino sketch using the Matlab Arduino support package syntax.

3) Use the standalone SingleTact Arduino sketch, available on the website, to read data from the sensor at a controlled rate, then output the data asynchronously to the PC. Then using Matlab to read the USB serial buffer, the data can be moved from the serial buffer to the Matlab workspace for further processing.

By far the easiest one to do, unless you are familiar with the Arduino support package, is (3), as it simply runs the Arduino and sensor in a free running mode and copies data from the serial buffer.

Hope this helps,

Rory

[Gerardo M]

Hi. I was looking at the datasheet of these sensors, my query is whether it can measure capable of dust in a desert place?

Thank you

[Rory Hampson]

Hi Gerardo,

Providing the sensors are bonded to your contact surfaces before being exposed to dust then they will be fine.
Care should be taken to control the temperature and humidity in such an environment.
For example, moving the sensor system from desert sunlight into the shade can cause condensation to form on the sensor. As such, you should take care to keep the sensors dry and isolated from such extreme temperature gradients.

As for dust, providing the dust is not highly electrically charged or moving at high speed (dust storm) you should be just fine.

[GHCorner]

Really finding this helpful.

[Ivan]

Can the sensor be programmed to not be reset while turning it off and on?

I want to install it, press it, unplug it while it is compress, do thermal cicles to the assembly, replug it and measure pressure differences before and after the cicles, How can this be done?

Thank you.

[CJ]

I am interested in the S8-100N and CS8-100N. However, there are 2 things that I would like to ask if anyone has done it before.

1) Is the sensors ultra-high vacuum compatible?
2) To fix the sensors, can I use some epoxy to glue the sensors? I am interested in distinguish between the state of when there is a load on the sensor and when there is no load on the sensor.

Thank you!

[Rory Hampson]

Excellent questions!
1) we don’t know how SingleTact sensor operate in vacuums. The dielectric is silicone based so there will be some degree of degassing which will void the calibration of the CS8-100N
The S8-100N should fare better as you can manually recalibrate them after several degassing cycles.

2)you can use 2 part epoxy resin to bond the sensors but:
It must be spread evenly over the sensor area
It must not well up and spread to the other side of the sensor.

3M 300LSE tape is recommended for general applications.

Hope this helped

Hello,

I am using two standard sensors with a Raspberry Pi. I would like to change their addresses so I can use them on the same I2C bus. Code looks something like this:

import smbus2
bus = 1
oldAddress = 0x04
newAddress = 0x06
device = smbus2.SMBus(bus)
device.write_i2c_block_data(oldAddress, cmd, [0x02, 0x00, 0x01, newAddress, 0xFF])

For writing the block using smbus.write_i2c_block_data, what should I pass as the cmd parameter? Does it have any effect on the Singletact I2C chip?

Thank you!

[Roto]

Hi,
I am currently using the Singletact with the arduino to measure tension but when I upload the program and run the demo it come back with the error Invalid Settings. I’ve tried changing the arduino board, the wires, force sensor and even the computer and I still get the same error. When I run it in the serial monitor it doesn’t change value even when I apply different force.
I was wondering if there were any other ideas why it wouldn’t work.

[Rory Hampson]

The sensors are not designed to measure tension, only compression.
Chances are that you are damaging the sensor

[Roto]

Sorry I meant compression my bad. I also don’t think the sensors are broken as it works when I use analog inputs and output.

[Mark Kelley]

Hi, a question from an Arduino novice…
My project is using the calibrated sensor CS8-1N with an Arduino Uno R3 & a PC running Windows 10
I am receiving the following error when running “SingleTact.Demo.exe”
“Failed to start sensor on COM4.
Please connect the Arduino and then restart this application.”
I am confident that communication w/ the Uno is established, as I can successfully execute the “Blink” demo.
The Uno shows up as COM4 when checked in the Device Manager.
I have tried this on two computers with the same error being thrown on both…
Can you please offer some pointers on how to debug this?
Thanks!

[Rory Hampson]

Hi Mark,

Make sure your Arduino is also running the software designed to communicate with the demo program.
You can find a link to the software download in our application note ST_AN_002, available from our website, which will explain how to get your system up and running.

Best of Luck,

Rory Hampson

[Mark Kelley]

Thank you Rory – I think that you are referring to the following steps , correct?

“1. Go to File —>Open and open “SingleTactDemo.ino”
2. Go to Sketch —>Include Library —>Add .zip Library and select “Timer1.zip”
3. Go to Sketch —>Verify/Compile.
4. Go to Sketch — > Upload*.”

If so, I had completed these steps prior to starting the “SingleTact.Demo.exe” so I am still having the error…

[Rory Hampson]

Yes I was, okay then.

Make sure your I2C lines are connected to your Arduino correctly, and you may need to use external pullup resistors on the lines if you have lots of interference (4K7 usually will suffice) and that 5V and GND are connected (sometimes you can get a loose connection)

Additionally, ensure that your sensor is mounted into its socket the right way around as per the quick start guide.

If your problem persists, you can try the standalone Arduino sketch which reads the data and you can just write it to a serial terminal. (this check will tell if the issue is on your PC or at the sensor)

[Chris Dancer]

I am just getting acquainted with the SingleTact sensor. I have a 15mm 45N sensor and I intend to use the analog output from the board.
I just tested it and it seems to be registering force. However there is a lot of noise / random drift in the signal, over 20mV pk-pk, about 2% of the full scale range. If this is normal for the sensor then sadly it makes it unusable for my application.
To eliminate the possibility that it might be some interference from my benchtop power supply I tried a 9V battery but the noise was the same.

Is this much noise normal?

[Rory Hampson]

Hello,

The analogue output should be properly isolated from the environment seeing as it is a small signal.
The noise measured largely depends on the method you are using to measure.

A certain amount of drift is expected as described in the datasheet.
Let the sensor stabilise to its operating temperature, you will notice the drift reduce.

[Chris Dancer]

Thanks Rory.
I’m using an oscilloscope to look at the output signal. I have allowed it to stabilise. What I’m seeing is small steps that look like quantisation noise, and superimposed on them is about 20mV of low frequency (<10Hz) noise that appears completely random. I think I can post an image here so I will try to do that.

Under ideal conditions and no force applied how much noise would you expect to see on the output of the electronics using this sensor?

[Chris Dancer]

[Chris Dancer]

I have since received some of the 8mm sensors and the noise voltage when using one of them is identical. It’s interesting that one electronic board consistently outputs more noise than the other, which points to it being a problem in the electronics rather than the sensor.
I have had to abandon use of these devices for this project as I can’t live with that amount of noise. At some point in the future I might look into designing my own electronics for the sensor.

[Renato Garcia]

Hello,

i bought a single tact 1N and I have questions about the scale used in the program chart. What scale is being used ( 0 – 500 )? I need to measure pressure. Also, I would like to know the usefulness of the variables that can be changed in the program ( ex: ic2 address, gain ). Is there a manual for the best use of software?

Thanks

[Rory Hampson]

The scale of 0-511 is in arbitrary counts.
You convert this to load using the following equation:
Load = (Output – Baseline) * Sensor_Rating / 512
