137 AC220240V 7A 5.8GHz 360 Degree Time Setting Microwave Sensor Radar Body Sensor Motion HF Detector Light Switch Why choose this microwave motion sensor Reliable automatic lighting control: Detects motion using 5.8 GHz frequency radar to switch lights on only when needed, reducing manual switching and unnecessary energy use. Wide, uniform detection: 360 degree coverage helps detect movement from every direction, eliminating blind spots common with directional sensors. Works with standard mains and loads: Designed for AC220240V circuits and safe for loads up to 7A, making it compatible with many household and commercial lighting fixtures. Key benefits and problem solving Hands convenience: Lights come on automatically when you enter a room and turn off after the set time, improving comfort and convenience. Better security and safety: Instant detection helps illuminate entryways, stairwells, and corridors when motion is detected. Energy and cost control: Prevents lights from being left on accidentally by using timecontrolled switching tied to motion detection. Simple integration: Designed to or add to existing lighting circuits without complex control systems. Main features and performance Sensing technology: 5.8 GHz microwave radar HF detector provides stable, penetrationcapable detection through light materials and performs well in varied lighting conditions. Coverage: 360 degree detection pattern for allaround presence sensing. Time setting: Adjustable time delay lets you choose how long lights stay on after motion stops. Load handling: Rated for AC220240V supply voltage and up to 7A load current for typical lighting fixtures. Motion detection type: Body sensor motion detection optimized for human movement. Compatibility and installation notes Compatible with standard AC220240V lighting circuits and fixtures that accept inline sensor switches and loads up to 7A. Intended for indoor use with common luminaires; consult an electrician if unsure about wiring or compatibility with specific lamp types. Compact design fits many typical switch and fixture installations. Practical applications Hallways and stairwells: Automatically light pathways when someone approaches, improving safety and reducing wasted ontime. Garages and utility rooms: Hands activation makes carrying items easier and ensures lights are not left on. Office corridors and storage areas: Provide occupancyaware lighting for cost control and convenience. What makes it stand out frequency microwave sensing for reliable detection across a full 360 degree field. Clear specification for voltage and current so you can confirm compatibility before installation. Time setting control to adapt behavior to different spaces and user needs. What to expect in use Immediate response to human movement, with adjustable off delay after motion stops. Stable performance in varied lighting conditions where traditional PIR sensors may be less effective. Straightforward replacement or upgrade of existing switchcontrolled lighting circuits when installed according to local electrical codes.
