Frequently Asked Questions

Is the Data acquisition software freely available?

Yes, the software is freely available from this link,

SingleTact RoHS compliant?

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

Will a demonstration be provided on how to use the sensor and make the relevant electrical connections?

The SingleTact quick start guide has detailed information ( ) about the pin configuration and experimental setup.

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

Double sided tape should be ok. 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. The following document will explain the differences in greater detail.

Can SingleTact sensors be custom-made?

Yes we produce custom sensors. 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 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:

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 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.
