4.3 Unit Switching (°C/°F)
The device supports switching between Celsius (°C) and Fahrenheit (°F) for temperature readings. Consult the device's physical buttons or on-screen menu (if applicable) for instructions on how to toggle this setting. Typically, a short press of a specific button or a menu option will allow you to change the unit.
4.4 Auto Calibration
The Coiliiot Air Quality Monitor features auto-calibration for its sensors, particularly the CO2 sensor. This function helps maintain measurement accuracy over time. For optimal performance, ensure the device is occasionally exposed to fresh outdoor air for a short period to allow the CO2 sensor to recalibrate to baseline levels.
5. Display Information
The monitor's display provides a comprehensive overview of current air quality. Below is a guide to understanding the various indicators and their corresponding air quality levels.

5.1 Air Quality Indicators
The display includes a multi-color indicator (typically green, yellow, red) to quickly assess overall air quality. Specific numerical values for each parameter are also shown.
5.2 Parameter Thresholds and Levels
The following table outlines the general thresholds for different air quality parameters, categorized into Good, OK, and Poor levels. These thresholds are based on common indoor air quality guidelines.
| Parameter | GOOD | OK | POOR |
|---|---|---|---|
| CO2 | <450 ppm | 450-1500 ppm | >1500 ppm |
| PM1.0/PM2.5/PM10 | <50 µg/m³ | 50-150 µg/m³ | >150 µg/m³ |
| TVOC | <0.3 mg/m³ | 0.3-1.0 mg/m³ | >1.0 mg/m³ |
| HCHO | <0.08 mg/m³ | 0.08-0.3 mg/m³ | >0.3 mg/m³ |
| Temperature | 64°F - 75°F | <60°F or >80°F | |
| Humidity | 30% - 60% RH | <30% RH, >60% RH | |
| AQI | 0 - 100 | 101 - 200 | 201 - 500 |
6. Maintenance
6.1 Cleaning the Device
To maintain optimal performance and appearance, regularly clean the exterior of the monitor with a soft, dry cloth. Do not use abrasive cleaners, solvents, or immerse the device in water. Ensure the sensor vents are free from dust and obstructions.
