Elecbee Interlink FSR402 Force Sensing Resistor Thin Film Force Sensor 0g-10kg for Arduino UNO R3 Robotics

FSR402 Force Sensing Resistor Thin Film Force Sensor for Arduino and Robotics Applications

Elecbee FSR402 Force Sensing Resistor (FSR) is a thin film force sensor designed to convert applied force into measurable resistance changes. As force increases, resistance decreases, allowing embedded systems and microcontrollers to detect touch, pressure, contact events, and object presence. The sensor is widely used in robotics, human-machine interfaces, educational electronics, and force-triggered control systems.
