Description: *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 enters the detection field, it will 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 will work day and night, when turn it to MOON (min), it will only work in the ambient light less than 3LUX. As for adjustment, please refer to testing way. Time-delay Adjustable:Can be set according to your desire, the minimum is 6sec, 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. Specifications: Quantity: 1pc Power Source: 110-240V/AC Rated Load: 1200W (incandescent lamp), 300W (energy-saving lamp) Detection Range:180° Power Frequency: 50/60HZ Detection Distance: 102m Ambient Light:
