Force Sensitive Resistor Sensor (Square)

This is a force sensitive resistor from sparkfun with a square, 1.75×1.5″ (44 x 38 mm), sensing area. This FSR will vary its resistance depending on how much pressure is being applied to the sensing area. The harder the force, the lower the resistance. When no pressure is being applied to the FSR its resistance will be larger than 1MΩ. This FSR can sense applied force anywhere in the range of 100g-10kg..

Sparkfun force Sensing Resistors (FSR) is a very thin, robust, polymer devices that decrease in resistance when pressure is increased on the surface of the sensor. It is used to sense pressure, weight, contacts and as a touch sensor. These sensors are simple to set up and great for sensing pressure.

This FSR will vary its resistance depending on how much pressure is being applied to the sensing area. The harder the force, the lower the resistance. When no pressure is being applied to the FSR its resistance will be larger than 1MΩ. This FSR can sense applied force anywhere in the range of 100g-10kg.
