Urban air quality monitoring systems work by using a network of sensors placed throughout urban areas to continuously monitor various air pollutants, such as particulate matter, nitrogen dioxide, ozone, and sulfur dioxide. These sensors collect real-time data on air quality levels, which is then transmitted to a central database where it is analyzed and made available to the public. By monitoring air quality in this way, authorities can identify pollution sources, assess the impact of emissions, and take action to improve air quality for residents.
