Force Sensor – 39.1 mm

The Force Sensor – 39.1 mm is a thin, flexible, and lightweight Force Sensitive Resistor (FSR) designed to detect and measure applied pressure, touch, or force. The sensor changes its electrical resistance based on the amount of force applied to its active sensing area. As the applied pressure increases, the resistance decreases, allowing the force level to be measured through a microcontroller or electronic circuit.

With an active sensing diameter of 39.1 mm, this sensor provides a larger sensing area compared to standard FSR sensors, making it suitable for applications requiring broader force detection coverage. Its slim and flexible construction allows easy integration into compact devices, wearable systems, interactive interfaces, and embedded electronics projects.

The sensor offers fast response time, good repeatability, and low power consumption, making it ideal for real-time force and pressure monitoring applications. It can be easily interfaced with platforms such as Arduino, ESP32, NodeMCU, Raspberry Pi, and other microcontrollers using a simple voltage divider circuit.

Force sensors are commonly used in robotics, human-machine interfaces, pressure-sensitive controls, smart devices, medical equipment, and educational electronics projects where touch or force measurement is required.
