Air Quality Monitoring app, is a numerical scale used to measure and report air quality in a specific area. The AQM provides information on how clean or polluted the air is and what associated health effects might be of concern to the public. The scale typically ranges from 0 to 500, with higher values indicating more significant air pollution and greater health risks.

Here's a breakdown of the AQI categories:

1) 0-50 (Good): Air quality is considered satisfactory, and air pollution poses little risk.
2) 51-100 (Moderate): Air quality is acceptable; however, for some pollutants, there may be a moderate health concern for a minimal number of people who are unusually sensitive to air pollution.
3) 101-150 (Unhealthy for Sensitive Groups): Members of sensitive groups (such as children, the elderly, and people with respiratory or heart conditions) may experience health effects. The general public is not likely to be affected.
4) 151-200 (Unhealthy): Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects.
5) 201-300 (Very Unhealthy): Health alert: everyone may experience more serious health effects.
6) 301-500 (Hazardous): Health warnings of emergency conditions will likely affect the entire population.
