#183787 - Infrared Transmission
Responding to: ???'s previous message
You may want to play around with infrared transmission for this application as well. It would be low cost to evaluate with an off the shelf remote control and an IR receiver attached to a simple MCU board to detect and decode the IR waveforms. You could increase transmit power easily by adding BJT buffer to the remote control transmitter so that you can force more current through the IR LED than you could with it just driving it from a pair of AAA type batteries. (Make that two BJTs so that you do not end up inverting the transmit signal).
