Try putting it under hardware, gives you better chances to get seen.
I have seen some RF modules that only the the transmitter is connected to the arduino board, and the receiver, just connects to what you are controlling.Have you done that before?I was thinking on having one arduino per sensor (or to group the close one), but if I can save using extra boards, even better.What do you think?Would it be the same approach if I use Xbee instead?
