Plan is to integrate with a sensor like a SGX IR12GJ, initially at least via an interface board that will provide Vout, maybe serial.

The board will need to deliver:

The board will need to read:

So an interface board will need to be made which has:

a transistor to deliver enough power to the sensor, driven by an output on the Arduino to generate the square wave, and
an instrumentation amplifier IC (op-amp) to deliver an appropriate analogue signal to the Arduino
