About this product
A Force Sensitive Resistor (FSR) is a thin sensor whose resistance drops as pressure on its active area increases. It is used to detect touch, squeezing and weight in device designs and test and measurement projects. The listing covers both Shunt Mode and Thru Mode FSR technologies, built from a semi-conductive material between two thin substrates.

Frequently asked questions
How do I read an FSR with a microcontroller?
Place the FSR in a voltage divider with a fixed resistor and read the midpoint voltage on an ADC pin. The fixed resistor value should be chosen for your force range and tuned by testing.
Can an FSR give exact weight readings?
FSRs give a repeatable change in resistance, but not precise force values by themselves. For accurate readings, calibrate your setup with known weights.
