Hello,
I'm currently working on a project which requires a wireless signal to be transmitted over a range of roughly 2 to 40 meters. The application involves several receivers but only one within said range at any given time, and if the transmitter works over too large a distance there will be unwanted activation of the other receiving modules. I've been considering purchasing the standard 433 MHz RF transmitter/receiver module from the picaxe store. I lack any significant experience in the radio/wireless world, and the cost of these modules kind of prohibits me from my usual approach (experiment until I discover the correct hardware/configuration). Any direction would be greatly appreciated!
