FSR406 Force Sensitive Resistor – Square Resistive Film Pressure Sensor

8.00 $

Description

The FSR406 is a square force-sensitive resistor that changes its resistance based on the applied pressure. The harder you press, the lower the resistance—making it perfect for detecting touch, pressure, and weight in Arduino, ESP8266/ESP32, and robotics projects.
