AVATTO HE20 WiFi Human Presence Sensor with mmWave 24GHz
If you are looking for a smarter and more accurate alternative to traditional motion sensors, the AVATTO HE20 WiFi Human Presence Sensor offers a more advanced experience through 24GHz mmWave technology. It can detect real human presence even without obvious movement by recognizing micro-movements such as breathing or slight posture changes, making it ideal for smart lighting, automation, and presence-based room control.
True human presence detection
- Powered by advanced 24GHz mmWave technology.
- Detects people even without obvious body movement.
- More accurate than many traditional motion sensors.
- Ideal for bedrooms, offices, and spaces where people may remain still for long periods.
3 detection states
- No one present
- Presence
- Motion
This gives users more flexibility when building smart automations based on the real room condition, not only on simple movement detection.
Wide angle and practical detection range
The sensor provides a detection range of up to 5 meters and a detection angle of 120°, making it suitable for living rooms, bedrooms, offices, children’s rooms, and many other indoor spaces. According to the provided specifications, detection accuracy can reach ±10 cm.
Works in all lighting conditions
One of the key advantages of the AVATTO HE20 is that it works effectively in both daytime and nighttime conditions, making it suitable for continuous smart home use regardless of room lighting.
Instant alerts and event records
The sensor can send instant push notifications to your phone when motion or presence is detected, and it also supports event history logging inside the app for easier tracking and review.
Smart integration with Tuya and Smart Life
The sensor works through WiFi 2.4GHz and integrates smoothly with Tuya Smart and Smart Life, allowing you to create smart automations such as turning on the lights when entering a room, switching off devices when no one is present, or activating air conditioning and curtains based on occupancy.
Voice interaction and room status
The sensor is compatible with Amazon Alexa and Google Home, and it can be used inside smart home routines and voice-based status checks depending on the platform setup and linked automations.
Adjustable sensitivity
- Low
- Medium
- High
This allows you to fine-tune the sensor performance depending on room size and the required detection style for better daily accuracy and fewer unwanted triggers.
Compact elegant design
The AVATTO HE20 features a compact and elegant round design that fits well into modern interiors. It can be mounted on the wall or ceiling depending on the desired coverage angle and installation environment.
