Feature: The motion detector adopts good sensitivity detector, IC. It accumulates automatism, convenient safe, energy saving, and practical functions. It uses infrared energy from human as the control signal source, it can start the load at once when entering the detection field. It can automatically identify day and night. It is easy to install and widely used. Descriptions:Delay automatically shuts off in the dark, automatic power on/off within 15s adjustable delay time after entering/exiting the induction range. Application Areas: For automatic lighting corridors, corridor, bathrooms, basements, warehouses, garages and other places, automatic exhaust fan and other electrical automatic control and other functions. Temperature compensation: chip temperature compensation, reduce the temperature impact detection distance.
