Smart Human Presence Detection: Equipped with advanced Zigbee technology, this sensor detects both movement and stillness, directly controlling connected lights for optimal energy efficiency. Lights turn on when presence is detected and off when areas are unoccupied, ensuring energy savings. Enhanced Privacy with 24G Mmwave Radar: Featuring cutting-edge 24G millimeter wave radar, this sensor captures even the slightest movements without the need for a camera, safeguarding your privacy. Ideal for maintaining illumination in static situations like reading without compromising security. Requires Zigbee Gateway: To function, this sensor necessitates a Tuya Zigbee gateway, serving as a central hub to link with other smart devices. It enhances your smart home experience with broad compatibility, supporting Home Assistant and Zigbee2MQTT for seamless integration. Effortless Installation & Broad Coverage: Designed for simple ceiling embedding, the sensor offers a substantial detection range up to 6 meters with a maximum installation height of 3 meters. Avoid placement near dynamic objects such as curtains to prevent false alarms. Customizable Settings via Tuya App: Tailor light sensitivity (10lux to 24H), duration (3-10s), and detection distance (1.5-6m) through the Tuya app. Choose between automatic or manual output modes to suit your needs, receiving real-time alerts and managing settings remotely.
