SingleTact Force Sensors – Frequently Asked Questions

What's the difference between the black, green and blue electronics boards?

The green boards are the first revision, they are being removed from circulation. The green boards are not supported with the tail extenders, this is only supported by the black or blue boards, this is the only difference. Blue board is the third generation released so far.

Is the data acquisition software freely available?

Yes, the software is freely available for download on our downloads page.

Is SingleTact RoHS compliant?

Yes, both the electronics and sensors are compliant, and the certificates are available on our downloads page.

How do you add this sensor to your project?

The SingleTact Quick Start Guide has detailed information about how to get started with SingleTact sensors, including the pin configuration and experimental setup.

We have also made a simple guide on How to Create a Force Sensitive Pad or Switch, which can help you integrate SingleTact products into your project.

What are your suggested methods of fixing the sensor to a flat surface?

Double sided tape is recommended. A very thin tape is preferable, so that it does not interfere with sensor performance.

How is the uncalibrated sensor different from the calibrated sensor?

A calibrated sensor has higher accuracy and a linear output curve, however calibration data is stored on the electronics, therefore the electronics cannot be used with any other sensor. For more information, go to our SingleTact Product Selector page, select any size, any pressure range, and then click on the informational “Should I order a calibrated sensor?” button.

Can SingleTact sensors be custom-made?

Yes, we can design custom sensors for you, however a minimum order value of $10,000 is required due to manufacturing costs. Please contact our sales department to discuss your project.

When I run SingleTact Demo, I receive an error message indicating an "invalid setting".

Check the pin configuration. To check that the Arduino is working properly with SingleTact, follow the steps in the SingleTact User Manual, Section 4.2 (Programming the Arduino UNO with SingleTact Example). Please make sure you have followed the current steps as well:

Go to Tools –> Board –>Arduino UNO

Go to Tools –>Port –> COM(X) (Connected with Arduino)

I want to use a SingleTact sensor without the interface board. Is it possible to measure the capacitance manually without the I2C interface board?

The available SingleTact datasheet gives possible sensor connections and the expected capacitance range. For your application, you need to read the capacitance value. You need some form of analogue front-end (SingleTact electronics or equivalent) to convert capacitance to voltage or a digital output.
