Tuya Zigbee mmWave Human Presence Sensor (Ceiling-Mount)
Overview
This Tuya Zigbee human presence sensor uses 5.8GHz mmWave radar to detect human presence, including static occupancy such as sitting or sleeping. Unlike traditional PIR sensors, it continuously monitors micro-movement and ambient light levels, making it suitable for bathrooms, bedrooms, offices, and automation scenarios where motion sensors fail.
The device integrates with the Tuya Smart / Smart Life app, Home Assistant or any zigbee network.
