1. [Functional Smart Human Presence Sensor] Features human presence, human static, human mini motion, and human movement detection to detect the presence or absence of individuals in the area, including accurate detection of static states such as sleeping, using mmWave radar technology. 2. [Perceived Light Intensity for Smart & Scene Linkage] Built-in illuminance monitoring enables smart scene automation with other compatible devices, such as automatically turning lights on or off based on ambient brightness. The sensor can be linked with other smart home devices for customized automation. 3. [Flexible in Use] Wall-mountable design allows installation on walls or other suitable surfaces. Compact and lightweight, powered via USB 5V. 4. [Advanced Design with Multiple Settings] Adjustable sensitivity levels (1–6), with detection range from 0.00 m to 9.5 m. Configurable hold time (0–1500 seconds) and detection delay (0–10 seconds) help reduce false alarms and support flexible usage scenarios. 5. [ZigBee Hub as Control Center] Requires a Tuya ZigBee gateway (sold separately) to function as a central hub for connecting and managing Tuya ZigBee smart devices, ensuring stable signal transmission and enabling whole-home automation.
