Circular Soft Potentiometer

Circular Flexible Potentiometer (Strip Sensor)

With this sensor, you can perform circular position measurements. Its adhesive back allows you to attach it to any surface you desire. The nominal resistance between the two outer legs is 10 kΩ. The resistance value at the center pin changes depending on the force applied to the circular strip. When no pressure is applied, there will be no resistance at the center pin, so it is necessary to connect it with a 100 kΩ pull-up resistor.

To use it, connect one of the outer pins to ground with a 10 kΩ resistor in series, and connect the other remaining outer pin to a positive voltage, such as 3V or 5V, using another 10 kΩ resistor. Do not connect it directly to a positive voltage without a resistor!
