Taiwan Alpha Membrane Pressure sensor - 44mm Square - with Female Pin Headers

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: Taiwan Alpha
• Type:  MF02-N-321-A01
• Active area: approximately 39.6mm x 39.6mm (square)
• Pressure range: 30 to 1000g (0.3 to 9.8N)  
• Has female pin header connectors for solder-free connection
