Figure 5.1: The sensor is powered by AAA Alkaline batteries. Ensure batteries are installed correctly.
5.2 Tải ứng dụng và tạo tài khoản
- Tải xuống Tuya thông minh or Cuộc sống thông minh Tải ứng dụng từ cửa hàng ứng dụng trên điện thoại thông minh của bạn (iOS App Store hoặc Google Play Store).
- Đăng ký tài khoản mới hoặc đăng nhập nếu bạn đã có tài khoản.
5.3 Ghép nối thiết bị
- Hãy đảm bảo điện thoại thông minh của bạn được kết nối với mạng. Mạng WiFi 2.4 GHz. The sensor does not support 5GHz WiFi.
- Mở ứng dụng Tuya Smart hoặc Smart Life.
- Nhấn vào biểu tượng "+" ở góc trên bên phải để thêm thiết bị.
- Select "Security & Video Surveillance" > "PIR Detector" or search for "Motion Sensor".
- Follow the on-screen instructions to put the sensor into pairing mode (usually involves pressing and holding a reset button until an indicator light flashes).
- Confirm the indicator light is flashing rapidly in the app and enter your 2.4GHz WiFi password.
- Wait for the device to connect. Once connected, you can rename the sensor and assign it to a room.
5.4 Gắn cảm biến
- Choose a suitable location for mounting. Consider areas where human movement is expected, such as hallways, entryways, or rooms.
- Ensure the chosen location is within the sensor's detection range (up to 6 meters) and has a clear line of sight.
- Làm sạch bề mặt lắp đặt kỹ lưỡng.
- Peel off the protective film from the double-sided adhesive provided.
- Attach the adhesive to the back of the sensor and then firmly press the sensor onto the desired wall or surface.
6. Hướng dẫn vận hành
6.1 Giám sát từ xa qua ứng dụng
Once paired, you can monitor the sensor's status and receive alerts directly on your smartphone through the Tuya Smart or Smart Life app. The app will display real-time notifications when motion or presence is detected.
6.2 Adjusting Sensor Parameters
Within the app, navigate to the sensor's settings to customize its behavior:
- Độ nhạy PIR: Adjust the sensitivity level (e.g., Low, Middle, High) to prevent false alarms or ensure detection of subtle movements.
- Keep Time (Cooldown Time): Set the duration for which the sensor remains in a 'triggered' state after detection. This prevents repeated triggers within a short period. The shortest setting can be 30 seconds, and the longest 120 seconds.
- Báo động chuyển động: Enable or disable motion detection alerts.
- Lower Battery Notification: Turn on/off alerts for low battery status.
- SMS/Phone Notification: Configure additional notification methods (may require subscription or specific regional services).

6.3 Scene Linkage with Other Smart Devices
Leverage the Tuya ecosystem to create smart scenes:
- In the app, go to the "Smart" or "Automation" section.
- Create a new automation.
- Set the condition: "When device status changes" > select your motion sensor > "Motion detected".
- Set the action: "Run the device" > select another Tuya-compatible device (e.g., a smart light, smart curtain, or smart alarm) > define the action (e.g., "Turn On", "Open").
- Hãy lưu lại quy trình tự động hóa.
7. Bảo trì
7.1 Thay thế pin
When you receive a low battery notification from the app, or if the sensor's performance degrades, replace the AAA Alkaline batteries promptly. Refer to Section 5.1 for battery installation instructions.
7.2 Vệ sinh
To ensure optimal performance, periodically clean the sensor's lens with a soft, dry cloth. Avoid using abrasive cleaners or solvents, as these can damage the device.
KHAI THÁC. Xử lý sự cố
- Sensor not detecting motion:
- Check battery level in the app and replace if low.
- Ensure the sensor is mounted correctly and has a clear line of sight.
- Adjust PIR sensitivity settings in the app to a higher level.
- Hãy nhận thức được cooldown time (Keep Time) setting. If the sensor was recently triggered, it will not re-trigger until the cooldown period has passed. This is normal operation.
- Thường xuyên xảy ra báo động giả:
- Adjust PIR sensitivity settings in the app to a lower level.
- Ensure the sensor is not facing direct sunlight, heat sources, or areas with significant air currents (e.g., near vents), which can cause false triggers.
- Sensor offline in app:
- Check your home's 2.4GHz WiFi network status.
- Ensure the sensor is within range of your WiFi router.
- Kiểm tra mức pin và thay thế nếu cần thiết.
- Try restarting the sensor by removing and reinserting batteries.
- If issues persist, try re-pairing the device with the app (refer to Section 5.3).

9. Lưu ý quan trọng và thông tin an toàn
- Thiết bị này yêu cầu Mạng WiFi 2.4 GHz for connectivity. It is not compatible with 5GHz WiFi networks.
- The sensor has a built-in cooldown time (Keep Time) after each detection. During this period, the sensor will not re-trigger, even if further motion is detected. This is a standard feature to conserve battery life and prevent excessive notifications. The cooldown time can be adjusted in the app from 30 to 120 seconds.
- Không để thiết bị ở nơi có nhiệt độ quá cao, ánh nắng trực tiếp hoặc độ ẩm cao.
- Để thiết bị tránh xa các trường điện từ mạnh.
- Thiết bị này chỉ được sử dụng trong nhà.
- Không tự ý tháo rời hoặc sửa chữa thiết bị. Hãy liên hệ với bộ phận hỗ trợ khách hàng nếu phát sinh vấn đề.
