Welcome to use Microwave Sensor! The product is a new saving-energy switch; it adopts microwave sensor with high-frequency electro-magnetic wave (5.8GHz), integrated circuit. It gathers automatism, convenience, safety, saving-energy and practicality functions. It works by receiving human motion. When one enters the detection field, it can start the load at once and identify automatically day and night. Its installation is very convenient and its using is very wide. Detection is possible through doors, panes of glass or thin walls. SPECIFICATION: Power Sourcing: 220-240V/AC Power Frequency: 50Hz HF System: 5.8GHz CW radar, ISM band Detection Range: 360° Ambient Light: <10-2000LUX (adjustable) Installing Height: 1.5~3.5m Rated Load: 1200W (incandescent lamp) Transmission Power: <10mW 300W (energy-saving lamp) Time-Delay: min.:10sec±3sec Power Consumption: approx 0.9W Max.: 15min±3min Detection Distance: 3-10m FUNCTION: motion sensor holder motion sensor motion sensor holder for bulb sensor light sensor switch motion sensor switch motion detect sensor
