Sensky 220V 1200W Ceiling mounted Microwave Radar Sensor Switch Detector for Led Lighting 220-240V/AC Microwave Radar Sensor Motion Detector Light Switch For Led Lighting Microwave sensor instruction: The sensor is an active motion detector,it emits high-frequency electro-magnetic wave (5.8Ghz) and receive their echo.The sensor detects the change in echo from even the slightest movement in its detection zone. A microprocessor then triggers the "switch light on" command. Detection is possible through doors,panes of glass or thin walls. Important : persons or objects moving towards the sensor are detected best! Specifications: power source: 220-240 volt Max load: 1200W Frequency: 50/60Hz Time delay: 10 seconds to 30 minutes Detection angle: 360 degree Working temperature: -15 to +70 C Ideal installation height: 2 - 4 meters Power consumption: 0.9 W Light control: 10-500LUX Detection distance : 2-8m (radius) adjustable Product size: Package size: 10*4.6*10CM Package include: 1 x Microwave Motion Sensor Switch,1 Manual Features: This microwave motion sensor reflects the latest development in interior lighting technology and provides close to zero energy wastage in terms of lights being on unnecessarily. Commonly used to control lighting and extract ventilation. Power-saving by ensuring lights and fans are not left on. They will save energy by ensuring lights and fans not to be left on. The energy savings will be high with a short energy saving investment payback time if connected to average energy level lighting such as fluorescent tubes, or compact fluorescent lamps. Higher savings if controlling tungsten or halogen lighting. The time of the light can last or adjust automatically when you enter and stay in the room and the light will go out according to the time of your your setting when you leave the room. Pluggable type of the terminals which make easier and much convenient to install. Applicable to monitoring equipment,warning facility, LED lamp, fluorescent lamp, incandescent lamp, ventilator and magnetic valve and so on. Can be installed on wall, ceiling and anywhere of your house. Indoor use only Note: The 220V fire line should be connected with L. The 220V zero line should be connected with N. The loaded fire line should be connected with L . The loaded zero line should be connected with the 220V zero line of the power source. _x000D_
