Tuya WiFi Human Presence Detector: 24GHz Radar Motion Sensor for Smart Homes

Meet the Tuya WiFi Human Presence Detector — a precision smart sensor that blends millimeter-wave radar with intuitive Tuya WiFi control for a seamless, proactive home automation experience. This upgraded mmWave 24GHz radar detector is designed to capture even subtle movements and presence, delivering reliable automation that adapts to your daily life.

Why 24GHz Radar Matters for your home

Compared with lower-frequency alternatives, 24GHz radar delivers sharper, more accurate presence detection. This module uses an FMCW (frequency-modulated continuous wave) algorithm to rapidly identify target range and motion, resulting in faster, more reliable recognition and lower false alarms. Key advantages include:

• Precision detection with rapid response and improved unmanned preprocessing speed
• Higher range and accuracy: detection ranges up to 0–1000 cm for movement and 0–840 cm for stationary presence
• Robust performance that can penetrate non-metallic obstacles like glass walls, widening automation possibilities

Integrated with Tuya WiFi — no hub needed

This version is designed for direct WiFi operation, eliminating the need for a Tuya Zigbee hub. Set up is straightforward through the Tuya smart home platform, letting you pair the detector with compatible scenes, automations, and voice assistants. It’s ideal for rapid deployment in living rooms, hallways, doors, and workspaces where hands-free control matters.

What makes this detector unique

Beyond the basics, this sensor is built for real-world use. Its 24GHz radar detects micro-movements and presence with high precision, enabling automation scenarios that respond to genuine activity rather than generic occupancy. Whether you’re turning on lights as someone approaches, adjusting climate when a room is occupied, or triggering security alerts when movement is detected after hours, this device offers nuanced control that standard PIR sensors can miss.

Use cases—how you’ll actually benefit

• Smart lighting: Lights turn on when you enter a room and dim or switch off after you leave, saving energy without sacrificing comfort.
• Smart climate: HVAC adjusts to occupancy, helping maintain comfort while avoiding unnecessary cooling or heating when rooms are empty.
• Home security: Detects presence to trigger alerts or integrate with cameras and alarms for smarter monitoring.
• Glass-wall environments: Radar’s penetrating capability enables reliable detection in spaces with glass partitions or doors.

What’s included in the package

• Human Presence Sensor x1
• USB cable x1
• User Manual x1

Placement and setup tips

To maximize performance, install the detector at waist to chest height for optimal sensing of human-sized movements. Avoid placing it behind dense materials or metal objects that can reflect signals in ways that create false positives. Use the Tuya app to create specific automations, such as “if presence detected in living room, turn on lights and adjust temperature to comfortable level.”
