Yes, the software is freely available from this link, https://www.singletact.com/software-download/
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 (https://www.singletact.com/QuickStart.pdf ) about the pin configuration and experimental setup.
Double sided tape should be ok. A very thin tape is preferable, so that it does not interfere with sensor performance.
SingleTact has been tested to a million cycles.
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. https://www.singletact.com/choosing-a-singletact/
Yes we produce custom sensors. Please contact our sales department (email@example.com) to discuss your project.
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) (https://www.singletact.com/SingleTact_Manual.pdf). 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 (https://www.singletact.com/SingleTact_Manual.pdf) 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.
