Air quality monitoring system and method

An air quality monitoring system configured to detect an air quality metric for a plurality of volumetric regions, the system comprising:

• a multiplexor configured to receive a plurality of air samples from each of the plurality of volumetric regions, the multiplexor comprising:
• a multiplexor housing having a base that defines a multiplexor sensor outlet and a cover that defines a plurality of multiplexor inlets in fluid communication with the plurality of volumetric regions, wherein the plurality of multiplexor inlets comprises a first multiplexor inlet that corresponds a measured volumetric region;
• a rotatable core defining a first core inlet;
• a power unit in electrical communication with the rotatable core and configured to rotate the rotatable core, such that the first core inlet is aligned with the inlet associated with the measured volumetric region;
• a sensor pack comprising:
• a sensor pack housing defining an interior cavity and a sensor pack inlet in fluid communication with the multiplexor sensor outlet and a sensor pack outlet;
• and
• at least one sensor disposed within the interior cavity, the at least one sensor configured to measure an air quality metric of the selected air sample;
• a sensor airflow line collectively defined by the multiplexor and the sensor pack, the sensor airflow line configured to fluidly couple one of the volumetric region inlets, the first core inlet, the multiplexor sensor outlet, the sensor pack inlet, the interior cavity, and the sensor pack outlet;
• and
• a controller in electrical communication with each of the power unit and the sensor pack, the controller configured to direct the power unit to actuate the multiplexor rotatable core between a plurality of positions to thereby align the respective multiplexor inlet with the sensor airflow line.
