3. Operating Instructions
3.1 Understanding the Display
The 2.8" TFT display provides a clear overview of all monitored parameters. Readings are updated in real-time.

Figure 4: Detailed view of the monitor's display, highlighting the various air quality indicators and their values.
The display typically shows:
- Temperature and Humidity: Current environmental conditions.
- AQI (Air Quality Index): An overall indicator of air quality.
- PM2.5, PM10, PM0.3: Particulate matter concentrations in µg/m³.
- CO2: Carbon Dioxide levels in ppm.
- CO: Carbon Monoxide levels in ppm.
- HCHO: Formaldehyde levels in mg/m³.
- TVOC: Total Volatile Organic Compounds in mg/m³.
- Battery Indicator: Shows current battery level.
- WiFi Status: Indicates connection status.
3.2 Interpreting Readings and Alarm System
The monitor uses color-coded indicators (e.g., Good, Slight, Moderate, Serious) to help interpret air quality levels at a glance. A dual-level alarm system provides visual alerts when pollutant levels exceed predefined thresholds, prompting users to take action such as ventilation.
3.3 Tuya WiFi Integration (Smart App Control)
The MT13W can connect to the Tuya Smart app for remote monitoring and advanced features. Refer to the Tuya Smart app's instructions for pairing the device and accessing its full capabilities, including historical data and custom alerts.

- Avoid fully discharging the battery frequently to extend its life.
- If storing the device for an extended period, charge it to about 50% and recharge every few months.
5. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low battery or power button not pressed correctly. | Charge the device for at least 30 minutes. Press and hold the power button firmly for 3-5 seconds. |
| Inaccurate readings. | Device not calibrated, placed in an unsuitable location, or sensor obstruction. | Perform a manual calibration in fresh air. Relocate the device away from drafts or direct pollutants. Ensure ventilation grilles are clear. |
| Cannot connect to Tuya WiFi. | Incorrect WiFi password, device too far from router, or network issues. | Verify WiFi password. Move the device closer to the router. Ensure your WiFi network is 2.4GHz (5GHz networks are often not supported by smart home devices). Restart your router and the monitor. |
| Battery life is shorter than expected. | Frequent use of high-power features, aging battery, or extreme temperatures. | Ensure the device is fully charged. Avoid operating in extreme temperatures. If the issue persists, contact customer support. |
