Walk up proximity detector
Ladies and Gents, I've been asked to provide some sort of proximity sensor for a client. Ideally it would draw a meager amount of current so it could run off batteries and have a detection range of 1 to 3 meters.
What they want is that when you walk up to a display it will automatically start the program, run for about 30 seconds and repeat.
Your thoughts or comments would be greatly appreciated.
