Avatto HE20 smart WiFi human presence sensor

Avatto HE20 smart WiFi human presence sensor

The Avatto HE20 is a human presence sensor that uses 24 GHz mmWave radar technology to accurately detect movement and presence in a room. The device analyzes body micro-movements, so it responds even to subtle gestures or changes in position – regardless of light intensity. As a result, it provides reliable operation both day and night.

High detection accuracy

The Avatto HE20 sensor distinguishes between three states of activity: no movement, presence and movement. With a detection angle of 120° and a range of up to 5 meters, the device effectively monitors the surrounding space, maintaining a distance measurement accuracy of ± 10 cm. Compared to classic 5.8 GHz sensors, the 24 GHz technology offers faster response and much higher precision. The device allows you to adjust the sensitivity level – the user can set the Low, Medium or High mode depending on individual needs and environmental conditions.

Smart home integration

With 2.4 GHz Wi-Fi connectivity and interoperability with the AVATTO App, Tuya Smart and Smart Life, the sensor can interact with other devices in automation scenes. When presence is detected, it can automatically turn on lights, curtains or an air purifier, creating a fully integrated and intelligent ecosystem.

Voice operation and in-app notifications

The device is compatible with Amazon Alexa and Google Home voice assistants, allowing you to check the status of a room with a voice command. The built-in Alarm Push function sends motion detection notifications directly to your smartphone, and you can also access the event history in the app.

Compact design and simple installation

The minimalist, circular design of the Avatto HE20 makes the sensor blend seamlessly into modern interiors. It can be mounted on the wall or ceiling – in the living room, office, bedroom or children’s room.
