This is a ceiling- or wall-mounted radar presence sensor that uses 24 GHz millimeter-wave technology to detect people who are still, not just people who move. It also has a built-in light sensor and a 110 dB+ alarm. That makes it a better fit for rooms where you want lights or automations to stay on while someone sits still, such as an office, living room or bathroom. Compared with passive infrared sensors, which drop out when a person stops moving, it holds presence through small movements like breathing. The trade-offs are that it needs constant USB power, it is a single-purpose sensor with no camera, and setup depends on the Tuya app and a Zigbee or Wi-Fi hub.

This human presence sensor combines 24 GHz millimeter wave radar with light sensing in one unit. The radar actively detects movement, including the chest movement of breathing and small movements of the body. This lets it recognize and locate a person who is sitting or lying still.
The built-in light sensor measures the brightness of the room.
