Round Force-Sensitive Resistor FSR-402 – 0.5″ Sensing Area (Bare Sensor)

From the shop's description

The Round Force Sensor(FSR402) is a force-sensitive module. At the end of the sensor, there is a round force-sensitive resistor, the resistance of which depends on the pressure applied to this resistor. Simply say, the greater the pressure, the smaller the resistance. However, the output of this sensor is not strictly linear, so we do not recommend it for accurate measurements. Application: Automotive electronics Medical Systems Industrial controls Robotics Interactive Educational Toy Features: Analog output Reliable mechanical structure High durability：Tested to 10 Million actuations, 1kg, 4Hz / -10% average resistance change Package Includes: 1 x Round Force Sensor (FSR402)
