" features: * Convenient and practical: The infrared motion sensor is energy saving automatic light switch, it adopts high sensitivity detector, and integrate SMT circuit. With a wide range of detection made up from top to bottom, service field left and right. (Horizontal 180 °, vertical 60 °, the maximum detection distance of 12m). * Principle of operation: It uses infrared rays human movement as sources of control signals, when one enters the detection field, it will start at the controlled charge at a time. * Identify Day and Night automatic: The ambient light of the PIR sensor switch could be adjusted according to your desire: when turn to SUN (max), it will work day and night, when turn to MOON (min), it will not will operate in ambient light less than 3LUX. Regarding the adjustment, please refer to test track. * Timed adjustable: It can be adjusted according to your desire, the minimum is 5 seconds, the maximum is 10 minutes. * Wide applications: It is widely used in intelligent lighting, easy installation on doors, corridors, elevators, balconies, bathrooms, mirrors, cabinets, cupboards, warehouses, cellars, garages, etc. Characteristics: Power supply: 220 V ~ 240V / AC (50Hz / 60Hz) Consumption: 0.45 W (work), 0.1W (static) Nominal load: 1200W (incandescent lamp), 300W (energy saving lamp) Timed: 5 s-10 min (adjustable by rotary knob LUX) Ambient light: 3LUX (night) -2000LUX (adjustable by the LUX rotary knob) LUX turn to the sun, day and night detection, LUX turn to the moon, feeling only night Detection distance: 12 ± 2 m Detection range: 180 ° Detection Travel speed: 0.6 ~ 1.5 m / s Installation Height: 1.8m ~ 4.5m Color: White, Black option Protection level: IP44 (for outside and inside) Operating temperature: -20 ~ + 40 centigrade Working humidity: <93% relative humidity Item Size: 87mm * 62mm * 100mm (L * W * H) Item weight: 116g / 4.1oz Information package: Package size: approach. 10.6 * 9.2 * 7.6cm / 4.2 * 3.6 * 3in Package weight: approach. 156g / 5.5oz List of packages: 1 * PIR infrared, motion detector 1 * Mounting screw 1 * User Manual (in English) "
