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 for energy savings and improved efficiency. Smart detection automatically delays power-off after the person leaves. Widely used in motion-activated lighting applications, such as corridors, bathrooms, basements, warehouses, and garages. USB-powered design allows convenient operation using a smartphone, power bank, computer, or laptop. Input voltage equals output voltage; low power consumption. Integrated temperature compensation chip minimizes detection distance variation due to temperature changes.
