I am working on a project which requires multiple RF working together (around 100). This will be one way communication from TX -> RX.
I will be setting up multiple cheap 433/315 Mhz in one particular area. How can I make sure that particular pair of RF doesn't clash/interfere with other pair. For every transmitter, there will receiver. No central receiver there.
I will add 8 bit Microcontroller on Transmitter side which will be connected to RF Transmitter and send data when required.
On receiver side I will add another micro controller to decode the packet and perform task accordingly.
I have read that upto 500 different channels can be selected which will avoid the interference, but couldn't find much info on that.
How can I solve the problem? Cost is a big factor or else I would have used HopeRF module in which network ID can be set and works with particular network.
