Features: Intelligent sensing: When the light is below 10LUX, it senses the human body and automatically turn on the light. After the person leaves, it automatically turn off, saving energy and electricity. Wide angles sensing: With a sensing angles of 120 ° and a sensing distance of 5m-8m, it ensures wide coverage and increases safety during use. Delay function: Adjustable delay time of 40-60 seconds, suitable for different scene requirements, allowing you to freely control the lighting duration. Stable performances: Great chips provide stable output, improving the reliability and service life of equipment. Supports multiple types of lighting fixtures, including incandescent lamps, energy-saving lamps, LED lamps, for easy installation.
