This pair consists of an RF transmitter and receiver. These can be interfaced with Encoder and Decoder ICs. For better accuracy, antenna should be used at transmitter and receiver ends.
We have two different 433MHz RF modules: the RXB6 and the FS1000A. Both of them runs with the same code and user interface.
