1. Connect the provided USB cable to the device's USB port and plug the other end into a 5V-1A USB power adapter (not included) or a computer USB port.
2. The device will automatically power on and begin displaying readings. It is recommended to keep the device plugged in for continuous operation due to the 2400 mAh lithium battery powering three sensors.
3. Allow the device to stabilize for approximately 30 seconds to obtain initial accurate readings.

3.2 CO2 Idiwọn

For optimal accuracy, especially upon first use, calibrate the CO2 sensor in an open, well-ventilated environment (e.g., outdoors).

1. Rii daju pe ẹrọ naa ti wa ni pipa.
2. Take the device to an outdoor area with fresh air.
3. Simultaneously press and hold the three buttons on the device for 200 seconds. The display will indicate calibration in progress.
4. Once calibration is complete, the device will return to normal operation.

The large LCD screen displays real-time readings for CO2 concentration, temperature, and humidity. A multi-color bar visually indicates the CO2 level status.

• CO2 (ppm): Carbon Dioxide concentration in parts per million.
• Temperature (℃/℉): Ibaramu otutu.
• Ọriniinitutu (%): Ojulumo ọriniinitutu.
• Aworan itan: Displays historical CO2 data over time.

4.2 CO2 Concentration Stages and Alarm

The device categorizes CO2 levels into three stages, indicated by color changes on the display and an audible alarm when thresholds are exceeded:

• Deede Stage: 400-700 ppm (Green indication)
• Warning Stage: 700-1500 ppm (Yellow indication)
• Dangerous Stage: 1500-5000 ppm (Red indication)

4.3 Customizing Alarm Thresholds

You can customize the CO2 concentration value at which the alarm will trigger.

1. Double-press the designated button (refer to Figure 2 for button layout) to enter the alarm setting mode.
2. Use the UP/DOWN buttons to adjust the desired CO2 alarm value.
3. Press the button again to confirm and save the setting.
