Description Automatic Induction: This motion sensor switch uses the human body motion infrared as the control signal source. When the person enters the detection area, the controlled load is started immediately, which is convenient to use.Energy Saving:This motion sensor switch outdoor can automatically identify day and night, and the motion sensor automatically turns on the light when motion is detected, making efficient use of energy, reducing waste, and saving energy and environmental protection.High Sensitivity: This motion detector light switch adopts high-sensitivity detectors, integrated circuits and SMT. When people leave,the lamp will auto delay power off, convenient and energy saving.Function: Auto switch on/off in the dark when you enter into the induction range, and the time delay has 3 way of 15 seconds, 45 seconds, 5 minutes adjustable .In addition to the automatic control of LED lights, it can also be used to control exhaust fans, doorbells or other devices.Applications: Which can be widely used in sports lighting, corridors, bathrooms, basements, warehouses, garages and other places.
