Motion Sensor Switch — Automatic, EnergySaving Outdoor Control Key benefits Hands convenience: uses human body infrared motion detection to start the connected light immediately when someone enters the detection area. Energy and cost savings: builtin day/night recognition only activates lighting when it's dark and motion is detected, reducing unnecessary runtime. Improved safety and deterrence: reliably lights outdoor areas after dark to improve visibility and discourage unwanted intruders. Reliable performance: sensitivity detectors with integrated circuits and SMT assembly provide responsive detection and consistent operation. Main features and functions Automatic induction: infrared motion sensing is the control signal source; the controlled load turns on instantly when motion is detected in the coverage area. Day/night identification: the sensor distinguishes ambient light levels so lights only switch on at night or in lowlight conditions. Auto delayoff: after motion stops, the lamp remains on for a preset delay then powers off automatically, saving energy while avoiding frequent switching. Construction and electronics: uses sensitivity detectors combined with integrated circuits and SMT manufacturing for stable, repeatable performance. Compatibility: designed for outdoor fixtures and suitable for both commercial and residential installations. Practical applications Home entry and porch lighting: automatically illuminate doorways and porches for safe arrival and hands access. Driveway and garage areas: provide immediate light when arriving home at night for safer vehicle access and unloading. Commercial perimeter and loading areas: enhance security and visibility in outdoor work zones, walkways, and building perimeters. What this product solves Eliminates the need to manually operate outdoor lights. Reduces energy waste by only activating lights in lowlight conditions and when motion is present. Enhances safety and security by ensuring outdoor areas are lit when occupied.
