3. Setup

3.1 Initial Charging

1. Before first use, fully charge the device. Connect the provided USB cable to the monitor's USB port and to a 5V, 1A USB power adapter (not included).
2. The battery indicator on the LCD screen will show charging status. Once fully charged, the indicator will show a full battery icon.

3.2 Placement

• Place the monitor in an area where you wish to measure air quality. Avoid placing it directly next to windows, air vents, or heat sources, as this may affect readings.
• Ensure the ventilation holes on the device are not obstructed to allow for accurate air sampling.
• The device can be placed on a flat surface or mounted on a wall using the integrated mounting holes on the back.

4. Operating Instructions

4.1 Powering On/Off

• To power on: Press and hold the power button located on the side of the device until the LCD screen illuminates.
• To power off: Press and hold the power button until the screen turns off.

4.2 Automatic Monitoring

Once powered on, the device will automatically begin monitoring CO2, temperature, and humidity. No manual calibration is required at startup. Readings will be displayed in real-time on the LCD screen.

5. Understanding the Display

The LCD screen provides clear, real-time data for various air quality parameters.

• CO2 Concentration (PPM): The central large number indicates the current CO2 level in parts per million (PPM).
• Color Ring Indicator: A colored ring around the CO2 reading visually represents the CO2 level:
  • Green: Indicates good air quality (low CO2).
  • Yellow: Indicates moderate CO2 levels.
  • Orange/Red: Indicates high CO2 levels, suggesting a need for ventilation.
• Temperature: Displays the ambient temperature in degrees Celsius (°C).
• Humidity: Shows the relative humidity (RH) percentage.
• Battery Indicator: Located at the top right, this icon shows the current battery charge level.

7. Maintenance

7.1 Cleaning

To clean the device, gently wipe the exterior with a soft, dry cloth. Do not use abrasive cleaners, solvents, or immerse the device in water. Ensure the ventilation holes remain clear of dust and debris.

7.2 Battery Replacement

The device is equipped with a replaceable 18650, 3.7V/1200mAh battery. If battery performance degrades significantly, you may replace it with a new battery of the same model and specifications, or a higher capacity 18650 battery. Ensure proper polarity when replacing the battery.

8. Troubleshooting

• Device does not power on:
  • Ensure the device is fully charged. Connect it to a power source using the USB cable.
  • Verify the battery is correctly installed if it has been removed or replaced.
• Inaccurate or fluctuating readings (CO2, Temp, Humidity):
  • Ensure the device is placed in a stable environment, away from direct airflow (fans, open windows), heat sources, or high humidity areas.
  • Check that the ventilation holes are not obstructed.
  • Restart the device by powering it off and then on again.
  • Allow the device to stabilize for a few minutes after powering on or moving it to a new location.
• Short battery life:
  • The device's battery life can vary depending on usage and environmental factors. For continuous monitoring, it is recommended to keep the device connected to a power source via the USB cable.
  • Consider replacing the 18650 battery with a new one, potentially with a higher capacity, if the current battery's performance has significantly degraded.
