Air Sensor technology advances and increasing availability in the consumer marketplace are changing the landscape of indoor air quality management. As air sensor technology evolves and becomes more widely used in relation to indoor air quality management, it is increasingly common for a sensor or a combination of sensors to be incorporated in equipment, appliances and other devices that measure, record, and/or display the concentration of certain pollutants or environmental conditions indoors. In addition, sensors are increasingly being used in devices to trigger an action, such as turning on an exhaust fan or air cleaner when pollutant concentrations or environmental conditions exceed a pre-defined level.
