0.5-Inch Force Sensitive Resistor Price in Pakistan
This thin force-sensitive resistor (FSR) changes resistance when pressure is applied to its circular active area. It is useful for touch controls, grip detection, robotics interfaces, pressure mapping experiments and other projects that need relative force sensing rather than laboratory-grade weight measurement.
Listed dimensions and characteristics
- Active detection area: approximately 14.5mm diameter
- Overall width: approximately 18.3mm
- Total length: approximately 56mm
- Thickness: approximately 0.4mm
- Passive variable-resistance output
Using an FSR with a microcontroller
Connect the sensor as part of a voltage divider and read the divided voltage with a compatible analog input. The response is nonlinear and varies with the contact surface, mounting pressure and unit-to-unit tolerance, so calibrate it inside the finished assembly rather than treating it as a precision scale.
Apply force to the active circle, support the sensor on a smooth surface and avoid sharp folds, creases or pulling on the tail. Do not solder for prolonged periods close to the sensing area.
For voltage-divider testing, connect the FSR to a suitable analog input on an Arduino UNO R3 and calibrate the completed mechanical assembly.

Frequently Asked Questions
How does a force-sensitive resistor work?
Its resistance decreases as force on the active sensing area increases.
Can this FSR measure precise weight?
It is better for detecting relative force or touch than precision weighing. Accuracy depends on mounting, contact area, calibration and the interface circuit.
How is the FSR read with Arduino?
Use it in a voltage-divider circuit connected to an analog input, then calibrate the measured values for the intended force range.
Does an FSR provide a linear force measurement?
No. Its resistance-to-force response is nonlinear and varies with mounting, contact area and individual sensor tolerance, so application-specific calibration is required.
Can the force-sensitive resistor be bent or folded?
The thin sensor can tolerate gentle flexing, but sharp folds, creases and pulling on the tail can damage it or change its response.
