2-way radio?

I would say that it is some kind of detector, looks like an antenna on top (and maybe bottom).

Looks like a cheap and nasty RF based doorbell or remote control transmitter. Poorly positioned SMD parts = cheap build quality, and corroded surround to push button = exposed to damp

Or the LED strips remote (haven't seen a motorola mcu on those cheap remotes though).

Nothing to do with LED's.
Some people are kinda-sorta on the right track, but still not close.

Foot-switch remote?

Rerouter · « **Reply #18 on:** October 09, 2012, 09:14:40 am »

the way the various active components are connected make it appear to be acting as an RF tranciever, something along the lines of, push button, sends command, recieves and processes data and send something back?
