Zigbee 24GHz mmWave Radar Human Presence & Motion Sensor

Upgrade your smart home with this advanced Zigbee 24GHz mmWave Radar Human Presence Sensor. Using cutting-edge millimeter-wave radar technology, it accurately detects not just movement but also stationary occupancy — including someone quietly sleeping or sitting still — making it far more intelligent than traditional PIR motion sensors. Compatible with the Tuya Smart and Smart Life ecosystems, it seamlessly integrates into your home automation setup.

Made in China Mainland.

Key Features

24GHz FMCW Radar Technology: Higher range detection accuracy, faster unmanned preprocessing speed, and more precise delay timing compared to older 5.8GHz or 10GHz radar sensors — all while meeting typical household detection distances.
Full Occupancy Detection: Detects human presence, micro-motion, movement, and static states (such as a person sleeping) with exceptional accuracy thanks to mmWave radar sensing.
Built-in Illuminance Sensor: Monitors ambient light levels (0–10,000 lux) and integrates with Tuya Smart APP for scene linkage — automatically turning lights ON/OFF based on brightness changes.
Highly Customizable Settings: Adjust trigger sensitivity (1–10), presence sensitivity (1–10), detection range (1–6m), and delay time (10–180s) to perfectly suit your space.
Requires Tuya Zigbee Hub: Works as part of the Tuya Zigbee ecosystem with a Tuya Zigbee gateway acting as the control center — providing an extremely stable signal for whole-home intelligence. (Tuya Zigbee hub is highly recommended for maximum compatibility.)
Ultra-Low Power & Battery Operated: Powered by 2× AAA batteries (not included) with an ultra-low-power radar chipset for an extended standby life — no wiring required.
Rotatable Multi-Angle Stand: Wall-mountable with a fully rotatable stand so you can always find the perfect detection angle for your room layout.

Frequently Asked Questions

Q: What makes this 24GHz mmWave sensor better than a standard PIR motion sensor?

A: Unlike conventional PIR sensors that only detect large physical movements, this 24GHz mmWave Radar Human Presence Sensor can detect micro-motions and static occupancy — such as a person sitting still or sleeping. The FMCW radar algorithm provides higher detection accuracy, more reliable delay timing, and faster occupancy state transitions, making it ideal for smart lighting and home automation scenarios.

Q: Does this Zigbee sensor work with Alexa, Google Home, or Apple HomeKit?

A: This sensor connects via the Tuya Zigbee ecosystem. When paired with a compatible Tuya Zigbee hub, it can be managed through the Tuya Smart or Smart Life app. Tuya integrates with Amazon Alexa and Google Home. Apple HomeKit compatibility may vary and is not officially guaranteed — a Tuya Zigbee gateway is required as the control center.

Q: How do I set up and install the Zigbee mmWave Radar Presence Sensor?

A: Install 2× AAA batteries (not included), mount the sensor on a wall using the included rotatable stand, and pair it with your Tuya Zigbee gateway through the Tuya Smart or Smart Life app. Once connected, you can customize the detection range (1–6m), sensitivity (1–10), and delay time (10–180s) directly within the app.

Q: What is the maximum detection range of this sensor?

A: The sensor has an adjustable detection range of 1 to 6 meters (default is set to 5m), suitable for most standard room sizes. The 24GHz radar is optimized for indoor household use, balancing detection coverage with accuracy.
