Convenient & Practical: The infrared motion sensor is energy-saving automatic lighting switch, it adopts high sensitivity detector, integrate circuit and SMT. With wide detection range made up of up and down, left and right service field. (Horizontal 180, vertical 60, Max 12m detecting distance.) Working Principle: It utilizes human motion infrared rays as control signal sources, when one enters the detection field, it start the controlled load at once. Identify Day and Night Automatically: The ambient light of PIR sensor switch could be adjusted according to your desire: when turn to SUN (max), it work day and night, when turn it to MOON (min), it only work in the ambient light less than 3LUX. As for adjustment, please refer to testing way. Time-delay Adjustable: It can be set according to your desire, the minimum is 5sec, the maximum is 10min. Wide Applications: It's widely used in intelligent lighting, easy installation on doorways, corridors, elevators, balconies, bathrooms, mirrors, wardrobes, cabinets, warehouses, basements, garages, etc. Power Source: 110V-240V/AC (50Hz / 60Hz) Power Consumption: 0.45W (work), 0.1W(static) Rated Load: 1200W (incandescent lamp), 300W (energy-saving lamp) Time-Delay: 5s-10min (adjustable by LUX rotary knob) Ambient Light: 3LUX(night)-2000LUX (adjustable by LUX rotary knob) LUX turn to sun, sensing day&night, LUX turn to moon, sensing only night Detection Distance: 122m Detection Range: 180 Detection Moving Speed: 0.6-1.5m/s Installation Height: 1.8m-4.5m Protection Level: IP44 (suitable for outdoor and indoor use) Working Temperature: -10 centigrade-+40 centigrade Working Humidity: Less than 93%RH Colour:Black Material:plastic Package Contents: 1 x PIR Infrared Motion Sensor Switch 1 x Mounting Screws 1 x English instruction manual(Due to different product batches, the appearance , which does not affect the use) Only the above package content, other products are not included.
