This is a 24 GHz millimeter-wave radar presence sensor that connects over 2.4 GHz Wi-Fi to the Tuya Smart Life app. Unlike passive infrared sensors, radar detects both moving people and people who are still, so lights stay on while someone sits at a desk or on a sofa. It is powered by USB-C at 5V and needs no hub. It suits people building room-level automation for lights, security and garage or door alerts. The trade-off is that it is app-only: the listing names Google Assistant and Alexa, but the description states voice assistants are not supported because there is nothing to control by voice.

This smart human presence sensor uses a 24G millimeter-wave radar to detect body movement and presence. It picks up both people who are moving and people who are staying still, including small movements.
It pairs over 2.4 G Wi-Fi with the Tuya Smart Life app, where you can control and adjust the sensor and your other smart home devices. It works with those devices to build home scenes. For example, lights can turn on when you enter a room and turn off when you leave. It can also sound a siren alarm for security.
It runs on 5V USB Type-C power and needs no hub. A wall bracket lets you mount it on a wall or wherever you need it. It suits lighting, security, garages, doors, smart homes and smart hotels.
