Patent attributes
An air sampling system configured to detect an air quality metric for a plurality of volumetric regions is disclosed. The system comprises an air sample return unit, an air flow controller, and at least one sensor. The air sample return unit is configured to independently transfer air from the plurality of regions as a plurality of air samples. The air flow controller is configured to receive each of the plurality of air samples and selectively direct a selected sample to a sensor supply line and the remainder of the samples to a sample purge line. The at least one sensor is configured to measure an air quality metric of the selected sample and communicate the air quality metric to a controller. The remainder of the air samples are directed to the air sample return unit throughout operation.
