01 — About

What it does

The Force Sensor Circle Shape detects applied force through a resistive polymer film that changes resistance with pressure. It provides an analog output proportional to the applied force for touch and pressure sensing.

Key features

Circle sensing area
Resistive force sensing
Analog output
Thin profile
Simple interfacing
Low power
Wide force range

Good to know

Use voltage divider with 10kΩ pull-down
Not precision sensor – qualitative measurement
Hysteresis present – different curves for increasing/decreasing force
Protect sensing area from sharp objects
