Force pressure sensors, also called force sensitive resistors are sensors that are used to detect physical pressure, squeezing and weight. FSRs are basically resistors that change their values when they’re subjected to pressure. The amount of pressure can be shown as an output to the user by measuring its instantaneous resistance. A force pressure sensor consists of a force sensing plate where the pressure is applied, and connectors that are connected to the circuit.

Safety Measures to follow
1. Verify that the supply voltage variation is within the rating.
2. Make sure that stress by forcible bend or pulling is not applied directly to the sensor cable joint.
