Spehro Pefhany said:I'm looking for a small, and low power, pair of RF modules (send
and receive, only one-way communication) that could be used to
send a couple of messages (specifically, "ON" and "OFF" commands)
with encoding so that stray RF won't cause it to malfunction (the
consquences are expensive, and possibly even dangerous). Maybe
something in the ISM band. If the transmitter works off a key fob
with a button cell, all the better. It would be nice if there was
no local oscillator or other leakage of signals from the
receiver. There will probably be a number of receivers and a
single transmitter. Range is not an issue (a few dozen meters is
fine).
I used modules from <http://www.rfsolutions.co.uk> Speff.
From Farnell, or Newark in the US.
