315MHz RF Transmitter Receiver Module Wireless Link Kit For Arduino

This is a 315MHz RF Transmitter and Receiver Module Wireless Link Kit designed for Arduino. Operating at 315MHz, this transmitter and receiver pair can easily be integrated into a breadboard and used with microcontrollers to establish a simple, one-way wireless data link. To create two-way communication, you would need two pairs of modules operating on different frequencies.

This wireless kit is ideal for controlling devices from up to 500 feet away. Simply connect the transmitter to your Arduino, Raspberry Pi, or other microcontroller, and the receiver to the device you wish to control.

Both the transmitter and receiver are tuned to the same frequency, so when the transmitter sends a signal, the receiver picks it up wirelessly. It offers an easy and convenient solution for wireless control. Compatible with Arduino & Raspberry Pi 2 / B / B+ / A+.
