The wireless TX (Transmitter) RX (Receiver) pair operates at 315 MHz radio frequency, they can easily plug and test into a solder less breadboard and work well with microcontroller to create a simply wireless radio data link. This 315 MHz Module will work communication data in one-way, you just need a two pair of a different frequencies to act as a transmitter and receiver pair.
These modules are indiscriminate and will receive a fair amount of noise both TX and RX works at common frequencies and don’t have a specific IDs. Therefore a method of filtering this noise and pairing transmitter and receiver will be necessary.
This module can be used in remote control switch, receiver module, motorcycles, automobile anti-theft products, home security products, electric doors, shutter doors, windows, remote control socket, remote control LED, remote audio remote control electric doors, garage door remote control, remote control retractable doors, remote volume gate, pan doors, remote control door opener, door closing device control system, remote control curtains, alarm host, alarm, remote control motorcycle remote control electric cars, remote control MP3.
