Tuya mmWave Human Presence Sensor

Tuya mmWave Human Presence Sensor
Zigbee or Wi-Fi · Radar-Based Detection · Replaces PIR

This mmWave radar human presence sensor provides true presence detection, not just motion. Unlike PIR sensors, it can detect stationary occupants (sitting, sleeping, working) using millimeter-wave radar technology.

Ideal for smart lighting, HVAC automation, energy savings, and security, this sensor integrates with the Tuya / Smart Life ecosystem and is available in Zigbee and Wi-Fi variants.

Key Features

• mmWave Radar Detection – Detects presence even without movement
• Superior to PIR – No false “vacant” states when occupants are still
• Wide Detection Coverage – ~90° field of view
• Luminance Sensor – Enables light-aware automations
• Two Variants Available:
  • Zigbee version (recommended for reliability and low latency)
  • Wi-Fi version (direct cloud connection)
• Tuya / Smart Life Compatible
• CE / FCC / RoHS Certified

Typical Use Cases

• Smart lighting that stays on while occupied
• Bathroom and bedroom automation
• Desk / office occupancy detection
• HVAC optimization
• Security and presence-aware alerts

Technical Specifications

• Detection Technology: mmWave radar
• Detection Angle: ~90°
• Detection Range: Up to ~6 m
• Connectivity: Zigbee or Wi-Fi (variant-dependent)
• Light Sensor: Yes
• Certifications: CE, FCC, RoHS

What’s Included

• 1× mmWave Human Presence Sensor
• Mounting hardware (if supplied by manufacturer)

Notes

• Zigbee version requires a compatible Zigbee hub
• Wi-Fi version connects directly to Tuya Cloud
• Not a Home Assistant–native device without Tuya integration
• Power method depends on model revision

This sensor is the correct choice when PIR is not good enough.
