Air Quality Monitoring

Air quality monitoring is the measurement and tracking of airborne pollutants: particulate matter (PM2.5, PM10), gases (NO2, O3, CO), and other indicators. Systems integrate sensors, wireless transmission, data storage, and visualization to provide real-time or near-real-time air quality intelligence. Applications: smart cities (public health warnings), industrial sites (EPA/EU compliance), research networks (atmospheric science), and consumer apps (personal exposure alerts). Data is typically stored in time-series databases (InfluxDB) and visualized in dashboards (Grafana, custom web apps).
