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!
