This is a Wi-Fi human presence sensor from Gaoducash that pairs mmWave radar with a PIR infrared probe, so it detects people who are present but barely moving, not just bodies that walk past. It connects directly over Wi-Fi through the Tuya Smart or Smart Life app, with no hub needed, and sends push alerts while keeping a 30-day activity record. Zone positioning lets you split an area and watch specific spots. It suits people who want occupancy-based automations, like lights that stay on while someone sits at a desk, or a quiet room alert for an elderly relative. Against plain PIR sensors it catches still occupants far better, but it is a wired-power device with a single detection point, so it competes with multi-sensor kits rather than replacing them.

This is a Wi-Fi human presence sensor that combines a built-in mmWave radar with an infrared probe. It detects both human movement and static presence. It can also pick up subtle movements by people or animals. Detection does not use a camera.
The sensor connects over 2.4GHz Wi-Fi and pairs with the Tuya Smart / Smart Life app. No hub is needed. The app sends alerts to your phone when it detects unusual motion and keeps 30 days of activity logs. Sensitivity can be adjusted.
A built-in light sensor lets you use light levels in lighting automations. The sensor can also join scenes with Tuya switches, curtains and other Tuya smart devices. It is powered by USB 5V and must stay constantly powered. It mounts with the included double-sided tape.
