Has anyone had any success hooking up the FlexiForce 100lb Pressure Sensor to the Arduino? This is what we have done:
We hooked up the the left pin to the 5V, the middle pin to ground, and the right pin to A0. This is the only setup that gives us a reading. Our problem is that when we slightly press on the pressure sensor, the serial monitor shows the maximum, 1023!
The schematic is here. http://www.tekscan.com/flexible-force-sensors#specifications
Are we required to use an opamp or is there some kind of code that can replace the opamp?
Thank you to anyone who points us in the right direction.
