The Auslese Robotics PIR Motion Sensor Switch is an intelligent lighting automation device designed to provide convenient, hands-free control of indoor lighting. Equipped with advanced Passive Infrared (PIR) technology, it detects human movement and automatically turns connected lights ON when motion is sensed and OFF after a preset delay. Compatible with AC 85–265V, this ceiling-mounted sensor helps reduce electricity consumption while improving safety and convenience. Its compact design, durable ABS construction, and reliable performance make it ideal for homes, offices, staircases, corridors, garages, basements, washrooms, hotels, warehouses, and other indoor spaces.
