IR Remote Control Relay

IR Remote Control Relay

In this project, we are going to build an IR remote control relay PCB that can control up to 4 onboard relays. This PCB can be used in different applications like where you need to wirelessly switch ON/OFF devices in your home or office from the comfort of your bed or chair.

What are infrared signals?

Remote controls such as those used for your TV, DVD/Blu-ray or Cable box use infrared transmitters and receivers. The transmitter is basically nothing more than a flashlight that emits a light beam at a frequency that is lower than the human eye can detect.
