More details in the documentation.



The sensor reduces the resistance of the windings when the effort to round of the tip increases. Due to this phenomenon, and the use of microcontroller Converter analog to digital, you can build a sensor that measures the force of impact. The measurement can be displayed, for example, on the LCD display.


In the absence of the force sensor, the resistance is approximately 1 mω. When przykładania finger with varying force meter showed 100 ohms to several hundred Ohms.
