Interlink Electronics FSR 402 Membrane Pressure Sensor - 18mm Round - Solder Tabs

This sensor is capable of measuring pressure by means of the membranes processed in the sensor.  
The resistance of the sensor changes based on the pressure on the membrane.
With a simple voltage divider you can easily read the sensor on an analog input pin on your Arduino.

Specifications:

• Brand: Interlink Electronics
• Type:  FSR402
• Active area: approximately 14.7mm (diameter, round)
• Pressure range: 0.2 to 20N
