6. Understanding Readings and Alarms
6.1 Air Quality Indicators
The monitor uses a color-coded system to indicate air quality levels for various parameters:
- Verde: Boa qualidade do ar.
- Amarelo: Moderate pollution.
- Laranja: Má qualidade do ar.
- Vermelho: Unhealthy air quality.

Imagem 6.1: Example of the multicolor indicator for PM2.5 levels.
6.2 Reference Table for Air Pollution Grades
Refer to the table below for specific concentration ranges corresponding to each air quality grade.
