The Interlink Force Sensing Resistor has an active sensing area of 0.5” (12.7mm) to sense applied force.
Force Sensing Resistors (FSRs) are very thin, robust, polymer thick film (PTF) devices that decrease in resistance when increased pressure is applied to the surface of the sensor. FSRs are not a load cell or strain gauge devices though they have many similar properties.
They are more appropriate for qualitative rather than precision measurements.

This force-sensitive resistor works best when connected to a voltage divider so you can customize the minimum and maximum voltage drop produced by the sensor with the expected minimum and maximum amount of pressure on the sensor. For more details on how to configure the voltage divider, take a look at the User Guide for the divider you choose.
