Tuya Smart Human Presence Sensor WiFi ZigBee & Lux Detection
Tuya Smart Human Presence Sensor with Luminance Detection
Transform any space into a truly intelligent environment with this advanced Tuya Smart Human Presence Sensor. Using precision millimeter-wave radar technology, it detects both active movement and subtle micro-motion — so your smart home automations respond accurately whether you're moving around or sitting quietly. Built-in luminance (lux) sensing adds an extra layer of intelligence, enabling light automation based on real ambient conditions, not just a timer.
Available in Wi-Fi (2.4GHz) and ZigBee 3.0 variants, this sensor integrates seamlessly into the Tuya Smart / Smart Life ecosystem and works with popular platforms including Amazon Alexa and Google Home.
Made in Mainland China.
Key Features
- Dual Detection Modes: Detects both macro movement (up to 1,000 cm / ~33 ft) and stationary micro-motion (up to 600 cm / ~20 ft) for accurate occupancy sensing.
- Built-in Luminance Sensor: Measures ambient light from 0–3,000 Lux to enable context-aware lighting scenes.
- Wide Detection Angle: Greater than 90° coverage for thorough room monitoring.
- Real-Time App Notifications: Instantly pushes alerts to the Tuya Smart app and triggers custom automation scenarios.
- Adjustable Radar Parameters: Customize micro/macro motion detection distance and sensitivity via the app to fit your specific space.
- Multi-Scene Automation: Works with smart switches, lights, and other Tuya-compatible devices — lights turn on when presence is detected and off when the room is vacant.
- Flexible Mounting: Available in wall-mounted (5V 1A) or ceiling-mounted (80–240V) configurations.
- Wide Compatibility: Ideal for bedrooms, living rooms, offices, conference rooms, hotels, and more.

Frequently Asked Questions
Q: What is the difference between the Wi-Fi and ZigBee versions of this human presence sensor?
A: The Wi-Fi version connects directly to your 2.4GHz home Wi-Fi network with no additional hub required, making setup quick and straightforward. The ZigBee 3.0 version requires a compatible ZigBee hub (such as a Tuya ZigBee gateway), but offers lower power consumption, faster response times, and a more stable mesh-network connection — ideal for larger smart home setups with multiple devices.
Q: Can this Tuya presence sensor detect someone who is sitting still?
A: Yes! Unlike basic PIR motion sensors, this radar-based sensor uses micro-motion detection technology to identify even very subtle movements, such as breathing or minor body shifts, within a range of up to 600 cm (~20 ft). This makes it highly effective for detecting stationary occupancy — perfect for smart lighting that should stay on while you're sitting at a desk or watching TV.
Q: Which smart home platforms are compatible with this sensor?
A: This sensor is fully compatible with the Tuya Smart and Smart Life apps (iOS and Android). Through the Tuya ecosystem, it also supports voice control via Amazon Alexa and Google Home, as well as integration with other Tuya-compatible smart devices like switches, lights, and thermostats.
Q: How is the luminance (lux) detection useful?
A: The built-in light sensor measures ambient brightness levels (0–3,000 Lux) and can be used to create conditional automations — for example, only turning on lights when a person is detected AND the room is below a certain brightness threshold. This helps avoid unnecessary lighting during the day and makes your smart home significantly more energy-efficient.
