Force Sensitive Resistor FSR402 Pressure Sensor

Force Sensitive Resistor FSR402 Pressure Sensor

The Force Sensitive Resistor FSR402 is a type of sensor that is used to detect and measure force or pressure. The FSR402 is a specific type of FSR that is designed to be sensitive to relatively small forces, making it suitable for use in applications where high sensitivity is required.

FSRs consist of a conductive material, such as carbon or metallic particles, that is embedded in a flexible polymer substrate. When a force is applied to the FSR, it deforms the substrate, causing the conductive material to make contact with additional areas of the substrate. This increases the overall conductivity of the FSR, allowing a current to flow through it. By measuring the change in conductivity of the FSR, it is possible to determine the magnitude of the force being applied to it.
