The Smart Human Presence Detector PIR – mmWave Radar Detection Sensor is a cutting-edge ceiling-mounted sensor designed to revolutionize how indoor spaces respond to people. Unlike conventional PIR (Passive Infrared) motion sensors that require movement to trigger detection, this advanced sensor leverages mmWave radar technology to perceive human presence through micro-movements—even when the occupant is sitting still, sleeping, or typing at a desk. It provides intelligent detection with unmatched precision, enabling more reliable and efficient smart automation in homes, offices, hotels, and public spaces.
With 360-degree detection from a ceiling-mounted position, this sensor ensures full room coverage from above, eliminating the blind spots that are common with wall-mounted detectors. The result is seamless and intelligent automation of lighting, HVAC systems, alarms, and other smart devices—all based on the actual presence of a person rather than just motion. The device is fully integrated with Tuya and Smart Life platforms, enabling you to set up complex scenes, adjust sensitivity, and remotely manage all detection functions through your smartphone.
Ideal for energy-conscious automation, the sensor intelligently turns off devices when no one is present, significantly reducing power consumption without compromising comfort or safety. It’s discreet, silent, and blends seamlessly into any ceiling. Whether you're upgrading your smart lighting system, improving building energy efficiency, or adding a subtle layer of smart security, this ceiling-mounted mmWave radar detector offers a level of reliability that traditional PIR sensors can’t match.
Advanced mmWave radar detection
Uses millimeter wave technology to detect even the smallest human motions such as breathing or shifting position, offering far more accurate detection than PIR sensors.
360-degree ceiling-mounted coverage
Mounts on the ceiling to provide a complete top-down detection field that eliminates blind spots and detects presence anywhere in the room.
Tuya/Smart Life app integration
Works with the most popular smart platforms for full remote control, automation, and real-time presence monitoring from anywhere in the world.
Customizable sensitivity and range
Adjust detection distance, response time, and movement thresholds to fine-tune performance to your exact room size and usage preferences.
Energy-efficient automation
Ensures lights, fans, or air conditioners only run when people are present—automatically switching off when a room is vacant, saving energy intelligently.
Discreet and silent design
Ceiling mount design ensures low-profile visibility and silent, maintenance-free operation with no blinking lights or sounds.
Scene-triggered automation
Supports advanced scenarios like triggering hallway lighting when someone walks through at night or activating alarms when unauthorized presence is detected.
No hub required
Connects directly to your 2.4GHz WiFi network, allowing simple installation and setup through your existing smart ecosystem.

The Smart Human Presence Detector PIR – mmWave Radar Detection Sensor offers far superior performance compared to outdated motion sensors. It’s capable of detecting still, seated, or sleeping individuals by measuring micro-movements, a feature that traditional PIR devices simply cannot achieve. This means it continues to recognize presence even when someone is quietly reading, watching TV, or typing—situations where normal sensors would assume the room is empty and turn everything off.
Beyond presence sensing, its real power lies in automation flexibility. You can create sophisticated smart routines through the Tuya or Smart Life app—like having hallway lights gently switch on when someone enters, or an air purifier activate only when someone is in the room. This intelligent behavior makes your home or workspace feel more responsive and alive, while saving energy and enhancing safety.

Q: What’s the difference between mmWave radar and PIR sensors?
PIR sensors detect only heat-based motion, while mmWave radar detects fine human micro-movements, making it more accurate and suitable for presence detection even when there’s no motion.
Q: Can this sensor detect a sleeping person?
Yes. Its radar-based technology is sensitive enough to detect breathing and slight shifts, making it ideal for bedrooms or spaces where people may be inactive.
Q: Is a smart hub required?
No. It connects directly to your home WiFi and works with Tuya/Smart Life apps without the need for a separate hub.
Q: Can it trigger my other smart devices?
Yes. You can use it to trigger lights, plugs, alarms, or other devices via automation scenes in the Tuya app.
Q: How is it powered?
It can be powered via USB or AC connection, depending on the installation preference and model variant.
Q: Will it work with Alexa or Google Assistant?
Yes, through the Tuya platform. You can create scenes and routines that integrate with your voice assistants.
The Smart Human Presence Detector PIR – mmWave Radar Detection Sensor is a sophisticated upgrade for any smart space. With superior detection accuracy, wide coverage, and intelligent automation capabilities, it outperforms traditional motion sensors in every way. Perfect for home, office, hotel, or retail applications, it provides both convenience and energy efficiency while staying nearly invisible and completely silent.
