Abstract: An indoor air quality (IAQ) system for sensing and controlling air quality within a structure is provided. The IAQ system includes a plurality of air quality sensor modules configured to sense IAQ parameters and remotely located within the structure. The IAQ system also includes an IAQ control hub including (i) a communication interface communicatively coupling the IAQ control hub to the plurality of air quality sensor modules and (ii) memory holding instructions that cause a processor to receive the IAQ parameters from the plurality of air quality sensor modules and if one of the IAQ parameters is outside a predetermined IAQ parameter range corresponding to the one of the IAQ parameters, request adjustment of control settings of a heating, ventilation, and air conditioning (HVAC) system to shift indoor air quality toward the predetermined IAQ parameter range.
