USB 5V 12V Light Sensor Switch Lighting Activated Photoswitch for LED Strip Features: The light sensor switch can turn the circuit ON and OFF by detecting the intensity of ambient light in real time. Suitable for automatic home lighting, car LED atmosphere lights, advertising sign LED displays, security monitors, cameras, and other devices. This product does not include motion or human body sensing (not a PIR sensor); it is a light-sensitive switch only. Ideal for automatic power control of electric equipment such as LED strips, cameras, and motors. Automatically turns on in low light or darkness and turns off when sufficient light is detected. Note: For Night-ON / Day-OFF operation with LED strips, ensure the LED light does not shine directly on the sensor to prevent flickering.
