Hello everyone!
Are you considering adding more smart devices to your home? If you’re diving into the world of home automation with Zigbee or Home Assistant, there’s a high chance you’ve come across the Tuya Zigbee Human Presence Detector.
Today, we’re going to break it down—its features, performance, comparisons, and practical buying tips—all in one place.
Specifications of Tuya Zigbee Human Presence Detector
The Tuya Zigbee Human Presence Detector is a compact, smart sensor built to detect not only motion but also presence through mmWave technology. It supports Zigbee 3.0 and works seamlessly with platforms like Zigbee2MQTT and Home Assistant.
| Feature | Details |
|---|---|
| Communication Protocol | Zigbee 3.0 |
| Detection Type | mmWave Human Presence + PIR Motion Sensor |
| Supported Platforms | Zigbee2MQTT, Home Assistant |
| Luminance Sensor | Yes (measures light intensity) |
| Distance Measurement | Available (for presence sensing) |
| Power Source | USB-C or DC (depending on version) |
| Mounting Options | Wall or ceiling mount |
Performance and Real-world Testing
The sensor stands out due to its dual detection system. While the PIR sensor reacts to motion, the mmWave technology goes a step further to sense even minor presence, like someone sitting still. This is a game changer for smart lighting or room-based automations.
Below are general performance metrics from users integrating it with Home Assistant:
| Test Scenario | Performance |
|---|---|
| Motion Detection Delay | < 1 second |
| Presence Detection Accuracy | Over 95% for small movements |
| Integration Response in Home Assistant | Instantaneous via Zigbee2MQTT |
| Daylight Sensing Accuracy | Accurate within ±10 lux |
Note: Proper placement is key for accurate presence detection. Avoid placing near fans or heating vents to prevent false triggers.
Use Cases and Ideal Users
This device is great for anyone who wants to go beyond simple motion detection. If you’re using smart automation to manage your lights, HVAC, or security systems, you’ll appreciate the mmWave sensing technology.
- Smart lighting that turns off when the room is empty, even if the person isn’t moving
- Presence-based climate control (HVAC turns off when no one’s around)
- Silent and accurate room occupancy detection in offices or study rooms
- Senior monitoring for inactivity or presence alerts
- Energy-saving automations based on occupancy
Recommended for: Home automation enthusiasts, smart home builders, developers using Zigbee2MQTT or Home Assistant.
Comparison with Other Zigbee Sensors
| Feature | Tuya Zigbee Presence Sensor | Standard Zigbee PIR Sensor |
|---|---|---|
| Presence Detection | Yes (mmWave) | No |
| Motion Detection | Yes | Yes |
| Luminance Sensor | Yes | Some models |
| Power Supply | USB-C/DC | Battery (AAA/CR123A) |
| Accuracy | Very High | Moderate |
As you can see, the Tuya sensor is in a different league when it comes to advanced presence detection. However, it may be overkill if you just need basic motion alerts.
Pricing and Buying Guide
The Tuya Zigbee Human Presence Detector is available from various global sellers and electronics suppliers. Prices typically range from $22 to $40 USD depending on the version and power options (USB or DC).
Buying Tips:
– Make sure the device supports Zigbee 3.0
– Look for versions with luminance and distance support if needed
– Prefer USB-C powered versions for stable performance
– Check firmware compatibility with Zigbee2MQTT or Home Assistant before purchase
Pro Tip: Join Home Assistant or Zigbee2MQTT communities to see which versions users recommend the most.
Frequently Asked Questions
What makes this different from regular motion sensors?
It detects static presence through mmWave, not just motion—making it more accurate.
Is it battery-powered?
No, it typically uses USB-C or DC input for continuous power.
Can it work with Zigbee2MQTT out of the box?
Yes, most versions are supported and well-documented in the Zigbee2MQTT device database.
Can I use it outdoors?
It’s not weatherproof, so it’s best used indoors.
Does it support automation triggers?
Yes, it provides multiple entities in Home Assistant that can be used for custom automations.
Is mmWave safe?
Yes, mmWave sensors use low-power radar and are safe for home use.
