Durable infrared motion sensors from SupplyApp are one of the simplest methods to cut energy use and running costs. When someone enters or departs a specific area, they can turn the lights on or off automatically. This sort of passive infrared sensor (PIR sensor), also known as a light sensor, is often mounted on walls or ceiling fittings. When the motion sensor detects movement in the room, it triggers a pre-programmed action, such as shutting off the lights. SupplyApp has a large selection of motion sensors in a variety of colors, configurations, and time delay options.
