Abstract
An air sampling system is configured to detect an air quality metric for a plurality of regions. The sampling system comprises an air sample unit and an air sensor in fluid communication with a sensor supply line and configured to measure the air quality metric. A controller is configured to control the air sample unit to selectively direct a selected sample of a plurality of air samples to the sensor supply line. The controller is further configured to control the air sample unit to direct the remaining air samples to a sample purge line bypassing the sensor supply line. The controller is further configured to change the selected sample over time among the plurality of air samples such that the air quality metric is identified for the plurality of regions.
