A 433MHz RF wireless receiver and transmitter module is a pair of electronic components that enable wireless communication between devices using radio frequencies in the 433MHz frequency band. Here's a breakdown of these modules:RF Wireless Receiver Module:
The RF wireless receiver module is design..
This RF Transmitter and Receiver module is ready to use with onboard 433Mhz RF Radio modules and encoder decoder ICs HT12E and HT12D for
better communication and DIP switches to avoid cross-connection with other
transmitters and receiver modules working at the same radio frequency..
