Tuya Smart WiFi Human Presence Sensor (mmWave Radar)

Product Overview

The Tuya Smart WiFi Human Presence Sensor uses advanced mmWave (millimeter-wave) radar technology to accurately detect human presence, including micro-movements such as breathing, even when a person is completely still.

Unlike traditional PIR motion sensors, this device provides continuous and highly accurate presence detection, making it ideal for smart lighting automation, energy saving, and indoor security applications.

⚠️ This listing is for the WiFi version only (2.4GHz). Zigbee is NOT supported.
