Price in Sri Lanka

This radio transmitter and receiver pair is perfectly matched to allow you to control items from a distance of up to 300 feet wirelessly! Connect the transmitter to your Arduino or other microcontroller, and the receiver to whatever you’d like to control. Both the transmitter and receiver are tuned to the same radio frequency, so when the transmitter emits a signal, the receiver will hear it wirelessly. Great for easy and simple wireless control!
