Radio frequency modules are compact gems that allow you to make any project wireless. Create your own remote control switch or windows by adding a receiver and transmitter to your home IoT devices. These 433MHz RF Transmitter and Receiver modules are a pair of limitless potential. Home automation projects are fantastic applications for this Tx/Rx Module Pair.

This Radio Transmitter & Receiver pair is perfectly matched to allow you to control items from a distance up to 500 feet wirelessly. Connect the transmitter to your Arduino, Raspberry Pi or other microcontroller and the receiver to whatever you'd like to control. Both the transmitter and receiver are in tune to the same Radio Frequency so that when the transmitter emits a signal, the receiver will hear it wirelessly. Great for easy and simple wireless control! Arduino & Raspberry Pi 2 / B / B+ / A+ Compatible!
