Detects no‑motion state, presence, and motion, responding even to micro‑movements. The wide 120° angle and up to 5 m range cover the entire room.
Wi‑Fi 2.4 GHz and the AVATTO App, Tuya Smart, and Smart Life let you automate lights, blinds, or an air purifier based on presence.
The minimalist circular shape fits perfectly into modern interiors. Wall or ceiling mounting is quick and clean.
AVATTO HE20 is a compact next‑generation presence sensor that uses a 24 GHz mmWave radar to detect “no motion / presence / motion” states with distance measurement accuracy of ±10 cm. It works reliably day and night and, unlike classic PIR sensors, responds to very subtle micro‑movements.
With Wi‑Fi 2.4 GHz and the Tuya ecosystem, you can easily create smart automations—when presence is detected, lights turn on, the air purifier starts, or the curtains close. Voice support for Amazon Alexa/Google Home and Alarm Push notifications give you full control even when you’re away from home.
