Force Sensor 0.5 inch Circular - 14.7mm FSR | Compoden
Force Sensor 0.5 inch (14.7mm) Circular
This is a compact force-sensitive resistor (FSR) with a 0.5-inch diameter sensing area. It changes resistance when pressure is applied, perfect for detecting touch, squeeze, or weight. The thin, flexible design easily integrates into wearable electronics, robotics, and interactive installations.

Compatibility
Works with any microcontroller with analog input, such as Arduino Uno, Nano, ESP32. Requires a pull-down resistor (10kΩ typical) to form a voltage divider. Operates at safe low voltages (3.3V-5V). Compatible with most single-supply ADC inputs.
Wiring Notes
Connect one pin to VCC, the other to an analog input through a 10kΩ resistor to GND. No polarity. For accurate readings, use a 10k-100k pull-down and calibrate for your specific force range. Avoid exceeding 10 kg to prevent permanent damage.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino?
Yes, simply connect one pin to 5V and the other to an analog pin via a 10kΩ pulldown resistor; read the analog value to detect force changes.
What is the maximum force it can reliably measure?
It can detect forces from about 100g up to 10kg. Beyond 10kg, the resistance change becomes nonlinear and may damage the sensor.
Can I use this in a wearable project?
Absolutely, its 0.45mm thickness and flexibility make it ideal for embedding into clothing, gloves, or shoe insoles.
