IR Light Switch

An IR motion sensor might respond by turning on a light after detecting motion by receiving infrared signals from people, living things, or any objects producing heat.

IR sensors might also perform a task when triggered by a beam of infrared light aimed directly toward the sensor by a light emitting diode .

The IR light switch operates indoors or out to turn on lights, fans, or other electrical devices.

Sensors in an IR light switch detect this energy and translate the signal into electric current, causing a light to turn on.

When used for outdoor safety or security, the light producing device generally contains the IR light switch.

The IR light switch usually screws into the light bulb socket and a light bulb screws into the outer end of the device.

Another type of IR light switch requires attaching the device to a live wire of a room wall switch or socket.
