LED sensor bulb is by the body's infrared thermal radiation theory and by MCU (microcomputer control unit) circuit design. It becomes active infrared measurement methods, a smart move, automatically switch and other characteristics. High sensitivity, easy for installing. Widely used on the motion-activated lighting, LED lights security system, automatic sensory device and more, same as the building, the balcony, kitchen, bathroom, warehouse, the elevator, children room, the hotel footpath, hotel need to be open and close automatically place.

LED sensor bulb can detect human movement by detecting infrared ray emitted by human body. When the temperature of the person or object into modules within the scope of induction, induction module will output a high pulse signal, or high level delay signal, the output pulse or delay the induction signal can be direct drive LED lights.
