More details in thedocumentation.



The sensor reduces its resistance when the force put to the tip, increases. Due to this phenomenon, and the use of microcontroller with analog to digital converter, you can build a sensor that measures the force of pressure. The measurement can be displayed, for example, on the LCD display.


When the force doesn't work on sensor, the resistance is approximately 1. When putting on the finger with varying force, meter showed from 100 to several hundredΩ.
