Force Sensitive Resistor (FSR) 0.6 inch

The Force Sensitive Resistor (FSR) 0.6 inch is a versatile, flexible, and ultra-thin pressure sensor designed to measure force or physical pressure applied to its surface. When force is applied, the resistance of the sensor decreases, generating an analog output that can be easily read by Arduino or Raspberry Pi.

This makes it an ideal component for robotic grips, touch-sensitive interfaces, medical devices, gaming controllers, and DIY force measurement projects.

Working Principle

The FSR operates on conductive polymer sensing technology. When pressure is applied:

• Conductive particles inside the sensor rearrange, reducing resistance.

• This resistance change converts to a variable voltage signal.

• The signal is read by a microcontroller’s analog input pin, allowing accurate measurement of force intensity.

📘 Formula:
Output Voltage = (Applied Force / Sensitivity Constant) × Reference Voltage

How to Interface with Arduino

1. Connect one end of the FSR to 5V, and the other to analog pin A0 via a 10kΩ resistor.

2. Measure the voltage using analogRead(A0).

3. Calibrate to convert readings into force or pressure values.

💡 Ideal for projects combining with:

• Arduino Boards

• Electronics Components

• Sensors and Modules

• Tools and Accessories

Precautions

⚠️ Avoid bending or twisting the sensor excessively.
⚠️ Do not expose to direct sunlight or high humidity.
⚠️ Apply uniform pressure for accurate readings.
⚠️ Operate only within specified voltage range.
