At its core, a Remote Control Relay is an electrically operated switch that enables the control of a device from a remote location. It typically consists of an electromagnetic relay that operates when it receives a control signal. This signal can be transmitted through various means such as wireless communication, infrared, Wi-Fi, Bluetooth, or even via the internet. When the relay receives the command, it switches on or off the connected electrical load, such as lights, motors, or appliances.

    Relays have been around for over a century, but their ability to be remotely controlled using modern wireless technologies has brought them into the forefront of smart home systems, industrial automation, and even automotive applications.
