One complete unit for quick installation: includes one microwave sensor switch so you can install or a sensor without extra parts. Why you need it: automates lighting control to eliminate manual switching, reduce wasted energy, and improve safety in areas where hands operation is helpful. How it solves problems: the sensor triggers lights only when motion is detected and lets you finetune how and when it responds, preventing false triggers and unnecessary run time. Key features and benefits Reliable microwave detection: operates at 5.8 GHz for consistent motion sensing and better penetration through light obstructions compared with ordinary PIR sensors. Adjustable light sensitivity and delay time: set the light sensitivity and choose the offdelay from 8 seconds up to 12 minutes to match the traffic pattern of the space. Built for safety and durability: constructed from flame‑retardant ABS material to withstand normal operating conditions and reduce fire risk. Simple replacement or retrofit: singleunit sensor switch makes installation straightforward and minimizes required parts. Practical applications Hallways and stairwells: automatically turn lights on when someone passes and keep them on only as long as needed to save energy. Garages and utility rooms: hands activation is convenient when carrying items and improves safety during lowvisibility tasks. Small commercial or service areas: use in back corridors, storage rooms, or restrooms where intermittent occupancy benefits from automatic control. Technical highlights (concise) Package: 1 microwave sensor switch Frequency: 5.8 GHz Delay time: adjustable from 8 seconds to 12 minutes Material: flameretardant ABS Function: motionactivated switch for lighting control This sensor switch provides precise, adjustable motion detection with safe construction and an easy singleunit installation—suitable wherever reliable automatic lighting control is required.
