FSR Force Sensor – 20g to 10kg Pressure Sensing Module for Force Detection Applications The FSR (Force Sensitive Resistor) Sensor is a compact and flexible sensor that detects physical pressure, force, or weight. With a sensing range from 20 grams to 10 kilograms, this sensor changes its resistance based on the force applied, making it ideal for measuring relative force in various interactive and embedded systems. Its lightweight and low-profile design allow easy integration into human touch interfaces, robotics, load-sensitive surfaces, and smart wearable devices. Whether you’re building a smart seat, robotic grip monitor, or a DIY pressure-based input system, the FSR sensor provides a reliable, analog output proportional to the applied force. Key Features Detects force or pressure from 20g to 10kg Thin and flexible form factor Analog resistance-based output Fast response time and long lifespan Easy to interface with Arduino, ESP32, Raspberry Pi, and other microcontrollers Ideal for touch, pressure, and weight sensing applications Product Specifications Feature Specification Sensor Type Force Sensitive Resistor (FSR) Force Sensing Range 0.2N to 100N (approx. 20g to 10kg) Output Type Variable Resistance (analog output) Sensing Area ~12mm diameter (varies by model) Thickness ~0.5mm Response Time <1 millisecond Repeatability ±2.5% of full scale Operating Voltage 1V – 5V (with voltage divider) Operating Temperature -20°C to 60°C Compatible Platforms Arduino, ESP32, STM32, Raspberry Pi, etc. Applications Pressure-sensitive controls Robotics and grip detection Load and weight sensing systems Smart textiles and wearables Gaming controllers and human-machine interfaces Seating, posture, and occupancy detection
