AC 220V Security PIR Motion Sensor Light Switch, 8m Range

This PIR motion sensor switch wires directly into a mains-powered AC 220V lighting or exhaust fan circuit, automatically switching the load on when someone enters its detection zone and keeping it on as long as occupancy continues, then switching off after a set delay once the area is empty. Unlike a basic timer switch, it responds to actual presence rather than a fixed schedule, which both improves convenience and genuinely reduces wasted energy from lights left on in an empty room or hallway.

Detection covers an 8 meter range across a wide 180-degree angle, giving solid coverage for a typical room, corridor, stairwell, or utility area from a single switch position. A built-in daytime lockout feature disables switching during daylight hours, specifically to prevent a light from triggering unnecessarily when there's already enough ambient light, which the listing credits with contributing to its claimed energy savings of more than 85 percent compared to a light left on continuously or controlled by a simple manual switch.

Switching uses a non-contact electronic design rather than a mechanical relay, meaning there's no electrical spark at switch-on or switch-off, which both avoids electrical interference with other nearby appliances and reduces wear on the switch itself over thousands of switching cycles. Delay time before switching off after the area clears is fixed at 40 seconds, long enough to avoid annoying flicker if someone briefly steps just out of detection range and back in.

The switch handles a 25 to 200W load rating, covering most LED, CFL, or incandescent lighting fixtures and small exhaust fans, and is rated for -20C to 40C operation with up to 93% relative humidity tolerance, giving it reasonable durability for bathroom, utility, or garage installation. Anyone wanting to add automatic, energy-saving occupancy-based lighting control to an existing mains circuit, without a smart-home system, will find this a simple, direct-wire solution.
