Tuya 4InOne Presence Detector - WiFi Zigbee PIR MmWave Motion Sensor Smart Homes

Tuya WiFi / Zigbee 4-in-1 Human Presence Detector – Smart mmWave Radar Motion Sensor

Meet a next‑level presence detector that blends PIR sensing with mmWave radar to accurately detect people and movement. Designed for homes and small offices, it powers intelligent scenes via ZigBee and optional WiFi, empowering true smart home automation with reliable occupancy detection.

• 4-in-1 Sensing: Detects human presence, static presence (like someone seated or sleeping), micro motion, and full motion using mmWave radar for nuanced occupancy awareness.
• Connectivity: ZigBee 3.0 core with optional 2.4G WiFi; works with Tuya Smart/Smart Life apps. A ZigBee hub is recommended for stable, whole‑home control.
• Detection Range & Angle: Stationary range 0–600 cm and moving range 0–1000 cm, with a 120° detection angle and up to 9.5 m sensing distance via mmWave radar.
• Illuminance Sensor: Light sensing from 0–3000 Lux to drive daylight‑aware automation and scene linking with other smart devices.
• Power & Environment: DC 5V / 1A supply; low standby current (<70 mA); operable from -10°C to 55°C and 0–95% RH.
• Easy Installation: Includes double‑sided tape for wall mounting and a rotatable bracket (optional) for flexible positioning.
• App & Scene Automation: Seamlessly integrates with Tuya Smart and Smart Life, enabling occupancy‑based automations and intelligent scene linkage with lights and other devices.
• Certifications: CE, FCC, UL certifications ensure safe, dependable operation across environments.

The sensor serves as a powerful occupancy sensor in smart home ecosystems, helping you reduce energy waste and improve comfort. By combining mmWave radar accuracy with traditional PIR sensing, it detects both movement and static occupancy—so lights, climate control, and other devices respond precisely when someone is present. The illuminance data adds another layer of control, letting your automations adapt to changing daylight and maintain ideal ambiance throughout the day.

Frequently Asked Questions

1. Q: What does 4‑in‑1 mean for this human presence detector?
   A: It combines PIR-based human presence, static occupancy detection, micro motion, and full motion tracking using mmWave radar, making it a versatile occupancy sensor for smart homes.
2. Q: Do I need a ZigBee hub to use this sensor?
   A: A ZigBee hub is strongly recommended for stable, whole‑home control. The device supports ZigBee 3.0 and works with Tuya ZigBee hubs for centralized automation.
3. Q: Is WiFi supported, and is it required?
   A: Yes, WiFi (2.4G) is optional. You can use ZigBee as the primary protocol and add WiFi for broader app access if desired.
4. Q: What is the detection range and angle?
   A: Static detection up to 600 cm, moving detection up to 1000 cm, with a 120° angle. MmWave radar contributes to accurate range and quick recognition.
5. Q: Can this sensor detect someone who is sitting or lying still?
   A: Yes—the 4‑in‑1 design includes static presence detection, so even non‑moving occupants can be recognized for appropriate automation.
6. Q: How does the illuminance sensor affect automation?
   A: The 0–3000 Lux sensor allows daylight‑aware scenes, so lights or shading can adjust automatically based on ambient brightness.
7. Q: Which apps work with this sensor?
   A: It integrates with Tuya Smart and Smart Life apps, enabling scene linkage and occupancy routines that tie into your broader smart home automation.
8. Q: What’s the difference between 5.8G and 24G radar for this product?
   A: 24G radar (as used here) offers shorter detection distances with higher accuracy (often around ±10 cm) and faster processing, which suits typical household use better than longer‑range 5.8G variants.
9. Q: How do I install the sensor?
   A: Mount on a wall using the included double‑sided tape or the optional rotatable bracket, then pair via the Tuya app or ZigBee hub. The device is powered by DC 5V and comes with a USB‑C cable for easy setup.
10. Q: What power supply does it require?
    A: DC 5V / 1A power supply; the unit draws under 70 mA in active mode and includes a 2 m USB‑C cable for connection.
11. Q: Is this sensor suitable for all rooms?
    A: Yes, it’s designed for indoor use with an operating range of -10°C to 55°C and 0–95% RH, ideal for living rooms, hallways, bedrooms, and offices.
