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.

The sensor has eight Vin and the ADC pins. For correct operation, the wire must be connected appropriately using any of the 4 deisgned for pins, fields. The sensors can be connected with each other.
