Force Sensor Resistor 38.1mm Square Pressure Pad - Thin Film FSR
This 38.1mm square Force Sensing Resistor (FSR) provides a variable resistance output proportional to applied force from 100g to 10kg. Its ultra-thin 0.45mm profile and breadboard-friendly 0.1″ pitch pins make it ideal for integration with microcontrollers like Arduino and Raspberry Pi via a simple voltage divider circuit and ADC input.
Features
- Square 38.1mm (1.5″ x 1.75″) active sensing area with peel-and-stick backing for easy mounting.
- Wide force sensing range from 100 grams up to 10 kilograms for versatile pressure detection.
- Ultra-thin 0.45mm profile enables integration into compact spaces and flexible assemblies.
- High-durability construction rated for up to 10 million actuations for long-term reliability.
- Simple two-pin interface (0.1″ pitch) for straightforward connection to ADC inputs on Arduino, Raspberry Pi, or other microcontrollers.

This Force Sensing Resistor (FSR) operates on the principle of piezoresistivity, where the electrical resistance through a conductive polymer decreases as mechanical force is applied to its active area. The sensor provides an analog resistance output, typically requiring an external pull-down resistor to form a voltage divider, the output of which can be read by a microcontroller’s ADC to infer applied force.
Designed for robust performance, the sensor features a durable construction capable of withstanding repeated use. Its ultra-thin form factor and adhesive backing allow for seamless integration into user interfaces, wearable devices, and embedded systems where discrete force profiling is required, though it is not intended for precision weighing applications.
