Infrared component

The Infrared sensor board contains both an IR transmitter and receiver. The transmitter is enabled via a digital control signal and the receiver provides an analogue output. By enabling the transmitter and reading the variable voltage output of the receiver it is possible to measure the distance of a reflecting object in the region of 1cm to 10cm.
