433Mhz RF Wireless Transmitter + Receiver Link Kit Module

This Radio Transmitter & Receiver pair is great for adding a wireless link to your projects. Allow you to control items from a distance up to 500 feet away 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. Compatible with Arduino & Raspberry Pi 2 / B / B+ / A+!
