The force sensing resistor detects force or the pressure applied. This sensor is basically a passive component which causes a decrease in resistance when an increased force is applied. Two pins come from the bottom part of the sensor which has a 0.1” pitch. At the other end of the sensing area, the FSR mounts a peel and stick rubber. Resistance of the sensor changes according to the pressure applied. Force sensors are considered to be simple, good for sensing pressure but the disadvantage is that it is not accurate. When pressure applied to the sensor is null, the sensor resistance will become large than 1Mohm.
