This is a Tuya-compatible presence sensor that pairs a 24 GHz mmWave radar with a PIR infrared probe and a light sensor. Unlike passive infrared motion sensors that only catch movement, it detects people who are sitting still, which makes it better suited to room occupancy and lighting automation. It runs on USB power, needs no hub, and reports to the Tuya Smart or Smart Life app over 2.4 GHz Wi-Fi with 30-day activity logs. It suits people building Tuya scenes for lighting, HVAC or security who want presence rather than motion, though the USB cable limits where it can go compared with battery PIR sensors.

This is a Wi-Fi human presence sensor that combines a built-in microwave (mmWave) radar with an infrared probe. It detects both human movement and static presence. It can pick up subtle movements by people or animals. It does not use a camera, so detection does not involve video monitoring.
The sensor works with the Tuya Smart / Smart Life app and needs no hub. It sends alerts to a smartphone when it detects unusual motion. The app keeps a 30-day activity log. Sensitivity can be adjusted. A built-in light sensor lets it trigger lighting automations, and it can be linked with Tuya switches, curtains and other smart products in scenes.
It is a wired sensor powered by USB at 5V and must stay constantly powered. A 3M sticker lets it attach to a wall or other surface. Pairing requires a 2.4GHz Wi-Fi network.
