3. Product Features
- Bezel-Less LED Screen: The device features a 3.5-inch LED screen with a minimalist design, ensuring clear and easy-to-read data display.
- High-Precision NDIR Sensor: Equipped with an advanced Non-Dispersive Infrared (NDIR) sensor for accurate CO2 detection. It also monitors temperature (14°F-140°F) and humidity. Note that CO2 levels naturally fluctuate, so readings will vary.
- 3-in-1 Air Quality Monitoring: Simultaneously displays CO2 concentration, temperature, and humidity. Readings are presented clearly with a 3-color indicator and facial expressions to denote air quality levels.
- Automatic Alarm Function: An audible alarm is triggered when the CO2 reading exceeds 1000ppm. This function can be quickly turned on or off using the designated function key.
- Long Battery Life & USB Charging: The built-in battery provides over 10 hours of standby time on a full charge. The device can also be powered in real-time via the included USB charging cable.
- Portable and Easy Operation: Designed for portability, this palm-sized detector features a simple one-button operation for switching on/off. It is suitable for use in various indoor environments.
4. Setup Guide
- Initial Charge: Before first use, fully charge the device using the provided USB cable and a compatible USB power adapter (not included). The battery indicator on the screen will show charging status.
- Power On/Off: Press and hold the power button (usually located on the top or side) for a few seconds to turn the device on or off. The screen will illuminate upon startup.
- Placement: Place the monitor in the desired location, ensuring good air circulation around the device for accurate readings. Avoid placing it near vents, windows, or direct heat sources.

5. Operating Instructions
- Reading the Display: The large LED screen displays the current CO2 concentration in parts per million (ppm), temperature in °F/°C, and relative humidity percentage.
- CO2 Indicator: The device uses a 3-color indicator (green, yellow, red) and corresponding facial expressions to visually represent CO2 air quality levels.
- Green (Happy Face): Normal CO2 levels (typically 400-999 ppm).
- Yellow (Neutral Face): Warning CO2 levels (typically 1000-1999 ppm).
- Red (Sad Face): Dangerous CO2 levels (typically 2000-5000 ppm).
- Alarm Function: When CO2 levels exceed 1000 ppm, the device will emit an audible alarm. To toggle the alarm sound on or off, press the designated function key.
- Temperature Unit Switch: If applicable, a button may be available to switch between Celsius (°C) and Fahrenheit (°F) temperature units.

6. Understanding CO2 Readings and Health Effects
Understanding the CO2 levels displayed by your monitor is crucial for maintaining a healthy indoor environment. The following table outlines typical CO2 concentration ranges and their potential effects:
| CO2 Concentration (ppm) | Potential Effects / Air Quality |
|---|---|
| 400-999 ppm | Fresh air, smooth breathing. Generally considered good air quality. |
| 1000-1999 ppm | Air may feel stuffy or "muddy." Some individuals may start to feel drowsy or experience mild discomfort. Ventilation is recommended. |
| 2000-5000 ppm | Can lead to headaches, drowsiness, sluggishness, inability to concentrate, rapid heartbeat, and mild nausea. Immediate ventilation is advised. Prolonged exposure should be avoided. |
Common sources of elevated CO2 include human respiration, industrial emissions, second-hand smoke, and general air dust. Regular monitoring and ventilation are key to maintaining optimal indoor air quality.

7. Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the device. Do not use abrasive cleaners, solvents, or immerse the device in water.
- Storage: When not in use for extended periods, store the device in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Care: To prolong battery life, avoid fully discharging the battery frequently. Charge the device regularly, especially if it will be stored for a long time.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Inaccurate CO2 readings / Fluctuating readings | CO2 levels naturally change; device may be near a vent or window; sensor calibration needed. | Ensure device is in a stable environment. Allow time for sensor to stabilize. If persistent, refer to manual for calibration steps (if available) or contact support. |
| Device not powering on | Low battery; charging cable not connected properly; device malfunction. | Charge the device fully. Ensure USB cable is securely connected. If problem persists, contact customer support. |
| Alarm not sounding | Alarm function is turned off; CO2 levels below alarm threshold. | Check if the alarm function is enabled. Verify CO2 levels are above 1000 ppm. |
If you encounter issues not listed here or if the suggested solutions do not resolve the problem, please contact KOPUO customer support for assistance.
