Welcome to using LX28 infrared motion sensor switch. The product is a new saving-energy switch, itadopts good sensitivity detector, integrated circuit and SMT. It gathers automatism, convenient safe, saving-energy and practical functions. Three detectors inside compose a wide range detection field, it utilizes the infrared energy from human as control-signal source, it can start the load at once when one enters detection field. Itcan identify day and night automatically. It is easy to install and used widely, possessing the functions of power show and detecting show.
