[Intelligent linkage] It can create intelligent scenes with Tuya switches, , curtains and other intelligent products to achieve energy saving, environmental protection, security alarm and other functions.Cooperate with other intelligent devices to realize rich automation and scene control. Make smart hardware react faster and control more smoothly. [Function introduction] Real-time detection of human presence, -motion detection (human breathing, heartbeat, deviated head, finger movement, raising head, turning around, swiping cell phone, flipping book, etc.), motion detection (walking, trotting, running fast, turning circle, jumping and other movements). [Accurate dynamic detection Static human presence] Static human presence This product uses advanced 24GHz millimeter wave radar technology to accurately detect whether there is someone in the area, breathing, heartbeat and other movements, whether moving or stationary. [Accurate identification and wide sensing range] human or animal movement Built-in high precision sensor, intelligent algorithm can accurately identify whether there is someone in the room, detect human breathing, heartbeat, swipe phone, movement and other dynamic static behavior. Ring detection range, sensing angle of 120 degrees Human -motion sensing radius of about 2 meters, motion sensing radius of 4 meters (installation height of 2-6 meters, ground projection) Linkage lighting scenes, people have not arrived at the regional lights can be pre-light, people to the induction area lights are brighter and brighter, people go after the lights slowly become dark easy installation Supports connection to ZigBee Can be connected to a cell phone Detects if there are people in the area safe and durable Colour:White Material:Plastic Size:8.8x8.8x5cm PackageContents: 1 * sensor Only the above package content, other products are not included.
