Force Sensitive Resistor Sensor (Square) made in USA

Overview

Meet the Force Sensitive Resistor (FSR) Sensor (Square) – a high-quality, made-in-USA pressure sensing solution from SparkFun. This robust sensor features a generous square sensing area (1.75 x 1.5 inches) that changes its electrical resistance in response to applied force. From feather-light touches to heavy presses, it accurately detects pressure from 100 grams up to 10 kilograms, making it an essential component for any electronics enthusiast, robotics engineer, or student.

Whether you're building a touch-sensitive interface, a weight measurement system, or an interactive art installation, this FSR offers reliable, analog output that your microcontroller can easily read. Its simple two-wire connection and low power consumption make it a breeze to integrate into your next project.
