🟩 Product Description

The FSR-402 Force Sensitive Resistor is a thin and flexible round pressure sensor that changes its resistance based on how much force is applied to the sensing surface. When pressure increases, the resistance decreases. With no force applied, the resistance is very high, and it gradually reduces as pressure is applied.

This sensor has a 0.5-inch (14.7mm) circular sensing area and can detect force in the approximate range of 100 grams to 10 kilograms. It is lightweight, ultra-thin and easy to integrate into robotics, wearable devices, pressure-sensing switches and research projects.

The sensor includes two pins spaced at 2.54mm, making it breadboard-friendly. It is simple to interface with Arduino, ESP32 and other microcontrollers using a basic voltage-divider circuit.

This sensor is ideal for detecting touch or pressure, but it is not intended for precise force measurement or weighing applications.
