A Tuya WiFi mmWave radar presence sensor that detects people even when they are still, such as someone sitting or sleeping, unlike PIR-only sensors that drop a still person. It also reads light level (0–2000 lux) so it can trigger lights only when the room is dark. Sensitivity, range, hold time and detection delay are adjustable in the Tuya Smart app. It suits people building automations for lighting, HVAC or occupancy alerts, but it needs constant USB power and a 2.4 GHz WiFi network.

Buyers of this class of Tuya mmWave sensor generally report that it keeps lights on while someone sits still, which PIR sensors fail to do. Complaints center on false triggers from fans, pets or movement through walls and on the need for USB power.
This is a pack of three Tuya WiFi human presence sensors. They use mmWave radar to detect whether people are in an area. They pick up presence, motion and small movements, and can detect a person who is still, such as someone sleeping.
A built-in illuminance sensor reports brightness in the Tuya Smart app. You can use it in scene linkage with other smart devices, for example to turn lights on or off as the light level changes.
The sensor is light and can be attached to a wall or wherever it is needed. It is powered by USB 5V. Sensitivity, detection distance, confirmation time and disappearance delay can all be adjusted to help avoid false alarms from irrelevant movement.
