Simple Infrared Barrier
by Maurizio @ dev.emcelettronica.com: Although a remote control is not so difficult to design and build, there is an even simpler option: the IR barrier. This consists of a constant IR signal permanently going from an emitter to a receiver, both of them being in two different places...
