The life presence function allows the sensor to detect very small body movements such as breathing and slight posture adjustments. This ensures that lights or connected devices stay on while people remain in the room, greatly improving comfort and safety. Equipped with a high- mmWave radar module, the sensor can detect body movements and micro-, achieving more accurate presence detection than traditional PIR motion sensors. It works reliably even in low light or complete darkness. Designed as a dedicated occupancy sensor, it continuously monitors whether people are present in the area. It can recognize when someone is sitting, standing or moving slowly, helping to avoid false " present" judgments and unnecessary light shutdowns. Compatible with both 110V and 220V , this human presence sensor is suitable for homes, offices, shops and public spaces in most regions. Easy to integrate into existing lighting and power circuits. Integrated motion sensor switch function supports automatic ON when presence or motion is detected, and automatic OFF after a set delay time when no presence is detected. Ideal for hallways, staircases, bathrooms, storage rooms, garages and more., Weight: 0.440924524 pounds, Manufacturer: NONDK
