Brand new and high quality. Infrared technology-based automatic motion sensor switch. Automatically turns on when people are detected, after people leave the delay, the lights automatically turn off. Applicable to the corridor, passage, toilet, warehouse, garage and other automatic lighting. Brightness measurement: Uses photosensitive control, it does not turn on the light during the day or in bright light environments, and can also adjust free induction lamps in all light environments. Delay: After it is opened, during the delay period if there is no human activity, the delay time at work, adjust properly freely within the scope of the delay time. Status indication: Induction effective LED indicator, convenient installation and fault analysis. Temperature compensation: With temperature compensation, reduce the induction distance affected by temperature. Automatically locked during the day to save energy. Easy to install or replace existing switch. Great solution for energy saving.
