1. An air quality monitoring system at a site having a private communications network adapted to carry data traffic, the air quality monitoring system comprising:

  • at least one sensor assembly programmed to collect air quality data at the site, the sensor assembly comprising;

    first and second air quality sensors adapted to measure a level of an air quality attribute, the first and second air quality sensors being coupled to a microprocessor and a data storage device;

    a communications device coupling the microprocessor to the private communications network;

    a public communications network coupled to the private communications network;

    an archiving and processing system at a remote data collection site comprising a controller programmed to automatically acquire over the public communications network air quality data from one or more sensor assemblies and to automatically store air quality data in a database;

    wherein the microprocessor is programmed to adjust sensor data from the first air quality sensor in response to sensor data collected by the second air quality sensor.
