    Are you thinking of building them on your own from scratch, or buying PCB modules, or buying complete off the shelf units?

    I recommend the latter. Much cheaper and faster overall.

    RFM12/22 or nRF24L01 for simple data transmission. You'll need a microcontroller, of course, to control it.
