When any one particular of them surpasses their protected array, an air high-quality inform is activated.
What is an air high-quality alert?
The AQI is divided into five groups, centered on the stage of pollutants in the air and the corresponding wellbeing hazard they pose. As a measurement device, the AQI spans from to 500.
