TUYA Smart Human Radar Sensor with Wi-Fi Connectivity

The TUYA Smart Human Radar Sensor is an advanced device designed to monitor occupancy within indoor environments using high-precision millimeter-wave technology. Unlike traditional motion sensors that rely on infrared heat signatures, this radar-based solution detects subtle movements, including breathing, to identify human presence even when a person is stationary. It connects directly to your home network via 2.4GHz Wi-Fi, eliminating the need for external hubs or gateways, and integrates seamlessly with the Tuya Smart or Smart Life applications for comprehensive control.

Advantages

This sensor offers superior accuracy by distinguishing between static human presence and environmental noise. Its ability to detect micro-movements makes it highly effective for rooms where occupants may remain still for extended periods, such as offices or bedrooms. The device provides flexible configuration options, allowing users to adjust sensitivity, detection distance, and delay times directly through the mobile app. Furthermore, the radar signal is capable of penetrating glass partitions, offering versatile installation options. With its compact design and included mounting hardware, it is a practical solution for enhancing energy efficiency and security through automated device management.

Suitable for

• Automated lighting control in rooms where occupants remain stationary.
• Smart climate control systems for heating and ventilation based on real-time occupancy.
• Enhanced security monitoring to detect presence in sensitive areas.
• Energy management systems to reduce power consumption in unoccupied spaces.

When it may not be suitable

This device is designed for indoor use only and may not perform reliably in outdoor environments exposed to weather. It is also not suitable for areas with high levels of mechanical vibration or moving machinery, which could potentially interfere with the radar signal and cause false detections.

Key specifications

• Power supply: DC 5V / 1A via USB Type-C
• Wireless connectivity: 2.4GHz Wi-Fi
• Stationary detection range: 0 to 600 cm
• Moving detection range: 0 to 1000 cm
• Detection angle: Greater than 90 degrees
• Illuminance sensing range: 0 to 3000 lux
• Dimensions: 60 x 60 x 12 mm

How to use

To begin, connect the sensor to a 5V power source using the provided USB cable. Download the Tuya Smart or Smart Life app on your smartphone and ensure your 2.4GHz Wi-Fi network is active. Use the app to pair the device, utilizing the integrated Bluetooth functionality for a faster setup process. Once connected, mount the sensor in your desired location using the included bracket or adhesive tape, ensuring it has a clear line of sight to the area you wish to monitor. Within the app, you can then configure sensitivity settings and create automation routines to trigger other smart devices based on occupancy status.

What to consider before purchase

• A 5V USB power adapter is not included and must be acquired separately.
• The device requires a stable 2.4GHz Wi-Fi connection for full functionality.
• Ensure the mounting location is free from large metal objects that could obstruct radar waves.

Usage recommendations

For optimal performance, position the sensor at a height that provides a clear view of the target area and avoid placing it directly behind thick concrete walls or metal enclosures, as these materials may block the radar signal.
