Consistent performance: 3.7GHz microwave sensing provides reliable motion detection in typical corridor and ceilingmounted scenarios. Easy integration: Designed for embedded ceiling mount installation to blend into finished ceilings and keep fixtures discreet. Wide voltage compatibility: Works across AC110240V electrical systems for use in many residential and commercial settings. Durable, practical design: Built for inceiling installation with a compact footprint that minimizes visual impact while providing stable operation. Features and attributes Function: Body motion detection with automatic switching for lighting circuits. Sensor technology: 3.7GHz microwave radar for motion sensing. Mounting: Embedded ceiling mount design for flush installation. Electrical compatibility: AC110240V supply voltage. Application focus: Intended for corridor and similar indoor passageway lighting control. Practical use scenarios Apartment building corridors: Automate hallway lighting to provide illumination only when residents or visitors are present. Office or commercial stairwells: Maintain hands lighting for safety and convenience during routine traffic without continuous ontime. Service rooms and storage areas: Control lights in seldomused spaces so lighting activates only on occupancy. Why choose this sensor This device provides a straightforward, dependable solution for automatic lighting control in ceilingmounted corridor applications. Its 3.7GHz microwave sensor and AC110240V compatibility make it suitable for a range of indoor installations where automatic, discreet lighting control is required.
