Setup

1. Unpacking: Carefully remove the air quality meter and all accessories from the packaging.
2. Initial Charge: Before first use, fully charge the device using the provided USB Type-C cable. Connect the cable to the meter's Type-C port and the other end to a DC5V 1A USB power adapter (not included) or a computer USB port. The charging indicator will show the charging status.
3. Power On: Press and hold the power button located on the side of the device for a few seconds until the LCD screen illuminates.
4. Placement: Place the meter in an area where you wish to monitor air quality. Ensure it is not placed directly next to air vents, windows, or sources of significant pollution (e.g., cooking fumes, chemical storage) for accurate readings. Allow the device to stabilize for a few minutes after powering on.

Operating Instructions

Real-time Monitoring

Upon powering on, the device will automatically begin real-time monitoring and display various air quality parameters on its 2.8-inch HD screen. The display provides a comprehensive overview of your indoor air quality at a glance.

Figure 3: Real-time Air Quality Monitoring. The device's screen shows current temperature, humidity, AQI, and detailed readings for various particulate matter (PM2.5, PM1.0, PM5.0, PM0.3, PM10), CO2, CO, HCHO, C6H6, and TVOC.

• Temperature & Humidity: Displayed at the top left and right corners respectively.
• AQI (Air Quality Index): A composite index providing an overall assessment of air quality, often color-coded for quick understanding.
• Particulate Matter (PM): Readings for PM2.5, PM1.0, PM5.0, PM0.3, and PM10 are shown in µg/m³.
• Gases: CO2 (ppm), CO (ppm), HCHO (mg/m³), C6H6 (mg/m³), and TVOC (mg/m³) concentrations are displayed.
• Color-Coded Display: The display uses different colors to indicate the air quality status for various parameters, making it easy to interpret the current environmental conditions.

Data Recording and Analysis

The meter features advanced data recording capabilities, allowing you to track air quality trends over time.

• Particulate Ratio Recording: The device can record the ratio of PM0.3, 0.5, 1.0, and 2.5 particles before and after a 1-minute interval, useful for observing immediate changes.
• Historical Data Curves: View data curves for PM2.5, HCHO, TVOC, and CO2 to understand concentration trends over 24 hours.
• Data Storage: The device can store data records for up to one year.
• Data Export: Connect the device to a computer via the USB Type-C cable to export stored records as TXT files for further analysis.
