The FSR-402 Round Force Sensitive Resistor Pressure Sensor  is a resistive thin-film pressure sensor that detects physical pressure, squeezing, and weight. It is a flexible, ultra-thin sensor with a sensing area of approximately 1.27 cm (0.5 inches) in diameter. When pressure is applied, the sensor’s resistance decreases, allowing for the measurement of force. The FSR-402 Round Force Sensitive Resistor Pressure Sensor by StemVolt is widely used in robotics, wearable devices, and educational projects. Its thin, flexible design helps students and DIY makers build compact and responsive pressure-based systems.
