The Moes ZigBee Smart mmWave Human Presence PIR Sensor combines 24GHz mmWave radar and passive infrared technology to detect both movement and static presence. While the PIR sensor captures motion up to 10 meters, the radar allows the device to sense a person even when they are completely still within a 6-meter range, covering a wide angle of at least 100 degrees. An integrated ambient light sensor measuring up to 3000 lux helps you automate lighting based on the actual brightness of the room. Constructed from white ABS and PC plastics, this compact sensor measures 72 x 32 x 38 mm and runs on two AAA batteries, which typically last over six months under normal operation. It connects via ZigBee 3.0 to your smart home hub, enabling you to customize sensitivity and detection ranges through an app. This makes it a practical choice for rooms where you want lights to stay on while you are reading or working, as it avoids the common problem of sensors turning off when no large movements are detected.
