With PIR motion sensor, it detects human motion by sensing infrared radiation emitted by the human body. 120-degree detection range. High and stable sensitivity, energy-saving and efficient. Smart detection automatically delays power-off after the person leaves. Widely used in motion-activated lighting for corridors, bathrooms, basements, warehouses, garages, and other areas. USB-powered: compatible with smartphones, power banks, computers, and laptops. Input voltage equals output voltage. Low power consumption. Integrated temperature compensation chip reduces temperature-related variation in detection distance.
