Mar 22, 2014 CHEAP FS1000a 433mhz transmitters revisited,
Hooked up two transmitters and one receiver. One Arduino was set to transmit “hello #1”, One Arduino was set to transmit “hello #2”, and one Arduino set to receive, Seems to work fine!
here’s a video:
So I was giving it the worse case, and the best chance to fail, and it seemed to work. By that I mean, both transmitters were right next to each other, the receiver was only a less the a foot away, and I put antennas on everything.
I don’t know for sure, but I had suspected this would work. I think it’s because of the modulation type, but I’m not sure about that either (not 100% sure). A lot of digital modulation types have built in error checking.
These are cheap, and a cheap way to send low speed data around.
