Infrared Motion Sensor YW03B is a ceiling-mounted PIR motion sensor with triple detector design, developed for large-area and high-sensitivity motion detection in commercial and industrial lighting systems.

Equipped with three PIR detectors, YW03B provides enhanced detection accuracy and a wider sensing coverage compared to standard single-detector sensors. It detects infrared radiation generated by human movement and automatically switches connected lighting loads ON or OFF, improving energy efficiency and user convenience.

With a 360° detection angle and a maximum detection distance of up to 16 meters, this sensor is especially suitable for open spaces where stable and long-range motion detection is required.

The adjustable time delay and ambient light sensitivity (LUX control) allow flexible configuration for different environments and applications.

YW03B is widely used in warehouses, corridors, parking areas, workshops, factories, and large commercial buildings.
