Description
This wireless transmitter and receiver pair operates at 315Mhz. They can easily fit into a breadboard and work well with microcontrollers to create a very simple wireless Receiving frequency (MHz) data link. Since these are only transmitters, they will only work communicating data one-way, you would need two pairs (of different frequencies) to act as a transmitter/receiver 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!
