By leveraging a microcontroller RS232 port as both a modulation source and detector, it is possible to make a simple proximity or through beam type sensor for very little cost.
A special bit pattern is used to eliminate any DC component in the RS232 signal making it compatible with the IR receiver.

Features

  • Cheap and simple proximity detector.
