Tuya Wi-Fi Human Presence Sensor (mmWave Radar)

Upgrade your home automation from basic motion tracking to high-precision detection with the Tuya Wi-Fi Smart Human Presence Sensor. Unlike traditional PIR sensors that fail when you sit still, this advanced device utilizes millimetre-wave (mmWave) radar technology to detect the micro-movements of human breathing, ensuring your smart lights and climate systems stay on while you are reading, working, or sleeping. Connecting directly to your home 2.4GHz Wi-Fi network without requiring an expensive central hub, it integrates a built-in light meter (Lux sensor) for automated day/night scene linkages. It is the ultimate solution for elimination of false cut-offs and creating fluid, responsive smart environments.

Key Features and Benefits

• Next Generation mmWave Radar Technology: Uses continuous wave radar signals to track large movements, micro-motions (like fidgeting), and static presence (like breathing) with unmatched accuracy.
• Continuous Presence Maintenance: Solves the biggest issue of traditional motion sensors by keeping your lights or automation states active even when you are sitting perfectly still.
• Integrated Lux Light Sensor: Features an onboard brightness meter (0 to 10,000 Lux) to create smart conditional rules, like turning on room lights only when someone enters and the room is dark.
• Advanced App Fine Tuning: Customize and optimize radar behavior directly through the Smart Life app, allowing you to fine-tune detection range boundaries, radar sensitivity levels, and target fade times to avoid false triggers from pets or fans.
• Hub Free Standalone Operations: Connects directly to a standard 2.4GHz Wi-Fi router, providing seamless global cloud management and rapid smartphone notification alerts out of the box.
• Seamless Automation Scene Linkage: Functions as a core trigger device within the Tuya ecosystem to gracefully orchestrate smart multi-gang touch switches, motorized curtains, and climate control configurations.

Common Use-Cases

• Smarter Home Office Lighting: Keep your desk spotlights active while typing or reading for long periods without having to wave your arms to turn traditional motion sensors back on.
• Living Room & Media Automation: Link the sensor to your smart switches so the room lights smoothly dim and remain turned off while watching movies, but illuminate softly if you get up to grab a drink.
• Energy Saving Bathroom Management: Ensure ventilation fans and overhead lighting stay operational throughout long bath routines, shutting down instantly after the room is fully vacated.
• Bedroom Sleep State Triggering: Configure static breathing detection boundaries to keep security rules inactive or run specific night climate setups when you are completely stationary asleep.
