FSR (Force Sensing Resistor) Sensor

This little module adopts a flexible nano pressure-sensitive material with an ultra-thin film pad to sense the exerted pressure.

When pressure is applied to the measuring disc, the resistance of the sensor will change. This change in resistance is converted to a varying output voltage using an additional resistor mounted on the module to form a voltage divider.

Compatible with Arduino and Arduino compatibles!
