Tuya
mmWave Presence Sensor (WiFi + Zigbee)
Finally, lights that stay on while you are sitting still. This 24GHz millimeter wave sensor detects human presence (not just motion), so your automations know the difference between an empty room and someone reading a book. Connects via WiFi or Zigbee to Home Assistant, Tuya, or any Zigbee coordinator.
Project idea: Automate your home office so lights, monitor backlight, and a fan turn on when you sit at your desk and turn off 30 seconds after you leave, with zero false triggers.
Key Features
- 24GHz mmWave radar: detects stationary humans by micro-movement (breathing, heartbeat), not just walking
- Dual connectivity (WiFi + Zigbee): choose your protocol based on your smart home setup
- Adjustable detection range and sensitivity: tune for your specific room size and layout
- Home Assistant compatible: works with Zigbee2MQTT, ZHA, or WiFi integration
- Ceiling or wall mountable: 120-degree detection cone covers a full room from one sensor
- No camera, no privacy concerns: radar-based detection, not optical
- Reports presence, distance, and sometimes target count depending on firmware version
Frequently Asked Questions
What is the difference between mmWave presence and a PIR motion sensor?
PIR sensors detect infrared changes from movement. If you stop moving, PIR thinks the room is empty. mmWave radar detects micro-movements like breathing, so it knows you are still there even when sitting perfectly still. The trade-off: mmWave sensors cost more and need tuning to avoid detecting through walls.
Will this sensor detect people through walls or in adjacent rooms?
It can. 24GHz radar penetrates thin walls and glass. Reduce the detection range in settings or position the sensor to point away from walls. Most firmware allows sensitivity adjustment to prevent false triggers from adjacent rooms.
