The Moes ZigBee Smart Human Presence Detector is a ceiling-mounted sensor designed to monitor room occupancy with high precision. By combining mmWave radar with PIR detection, it can distinguish between active movement and static presence, meaning it will keep your lights on even when you are sitting still or sleeping, avoiding the common issue of sensors timing out while you are still in the room. This device operates via the ZigBee protocol and requires a Tuya ZigBee hub to connect to your smart home system. It offers a detection range from 0.3 to 9 meters, with sensitivity levels that you can adjust from 1 to 9 to suit the specific layout of your space. To ensure the lighting reacts naturally, you can configure the detection latency and the hold time, which determines how long the sensor waits before deciding a person has left the area. Measuring 93mm in diameter and 30mm in height, the sensor integrates discreetly into your ceiling. It also monitors illuminance levels up to 2000 lux, allowing you to create automations that only trigger when the room is actually dark. Because it is powered by AC 100V-250V, you won't have to worry about replacing batteries, making it a reliable choice for hallways, bathrooms, or living rooms where constant, hands-free automation is useful.
