Product: sensor Size: B (Model B, Mini Version 24GB) Color: White Material: ABS Dimensions: 8.5 x 8.5 x 2.7 cm Model options: Model A (Mini for Zigbee Version 24GB), Model B (Mini Version 24GB) Key benefits Reliable smart home integration: Zigbee 3.0 protocol support enables seamless connection with compatible smart home systems for automated control of lighting and appliances. True presence detection: Millimeter wave sensing detects static human presence through micromovements such as breathing, providing presence information at distances up to 8 meters. Context aware responses: Dual sensing combines motion detection and ambient light measurement so the device adapts actions based on both occupancy and lighting conditions. Flexible placement: Install on a wall, ceiling, or surface to suit different room layouts and coverage needs. Compact and discreet: Small white ABS housing blends into most interiors while maintaining a low profile. Features Zigbee 3.0 protocol compatibility for integration with Zigbeebased hubs and automation platforms. Millimeter wave sensing with up to 8 meter range for detecting subtle human micromovements and static presence. Light sensing for ambient illumination monitoring and smarter scene decisions. Smart scene recognition to automatically identify scenarios and trigger lighting or appliance actions without manual intervention. Multiple installation options: wall mount, ceiling mount, or surface placement. How it solves common problems Prevents unnecessary lighting and appliance use by detecting true occupancy rather than relying on motion only. Provides reliable presence detection in situations where traditional PIR sensors miss stationary occupants. Simplifies automation setup by recognizing typical room scenarios for hands adjustments to lights and devices. Fits into varied room layouts thanks to multiple mounting options and compact size. Typical applications Hallways and entryways: Automatically turn on lights when someone is present, and adjust based on ambient light level. Living rooms and bedrooms: Detect stationary occupants to keep lighting and climate control responsive during low movement periods. Offices and meeting rooms: Monitor occupancy for automated lighting and equipment control without visible sensors or wiring changes.
