Force Sensor 5.08mm Circular – Compact Force Sensing Resistor

The Force Sensor 5.08mm Circular is a small force sensing resistor (FSR) that changes resistance based on applied pressure. It is ideal for integrating into tight spaces where precise force measurement is needed, such as wearable tech, medical devices, or robotics fingertips. Its thin, flexible design allows easy mounting on curved surfaces and provides reliable readings for both momentary contacts and sustained pressures.

Key Specifications

What You Can Build With This

• Simple digital weighing scale with an Arduino and LCD display
• Touch-sensitive button that triggers an action when pressed
• Interactive stress ball that controls LED brightness based on squeeze force
• Cat detection mat that sends a notification when your pet sits on a cushion

Compatibility

This sensor works with any microcontroller that has analog input, including Arduino Uno, Nano, Mega, Raspberry Pi Pico, and ESP32. For Raspberry Pi single-board computers, an external ADC (like MCP3008) is required. It operates at 3.3V–5V, making it compatible with most maker boards. Common pairings include the ADS1115 for I2C-based 16-bit readings.

Wiring Notes

Connect one terminal to Vcc (5V or 3.3V), the other terminal to ground through a 10kΩ resistor, and tap the junction to an analog pin. The resistor value can be adjusted (1kΩ–100kΩ) to shift the sensitivity range. Ensure connections are secure; soldering directly to the thin leads may damage the sensor—use a connector or conductive tape.
