315Mhz RF Transmitter and Receiver Module link kit

This Radio Transmitter & Receiver pair is perfectly matched to allow you to control items from a distance up to 300 feet wirelessly! Connect the transmitter to your Arduino or other micro controller 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!
