Abstract: An air quality measuring device that includes a first chamber, a second chamber, a third chamber, and a fourth chamber. The first chamber includes a first inlet configured to receive a first airflow, a first outlet configured to receive a first portion of the first airflow, and a second outlet configured to receive a second portion of the first airflow. The second chamber includes a second inlet configured to receive the first portion of the first airflow and a first sensor disposed within the second chamber. The third chamber includes a third inlet configured to receive the second portion of the first airflow and a second sensor disposed within the third chamber. The fourth chamber includes a fourth inlet configured to receive the second portion of the first airflow and a third sensor disposed within the fourth chamber.

Abstract: A method of monitoring a heating, ventilation, and air conditioning (HVAC) system to detect installation location of at least one indoor air quality (IAQ) monitor. The method includes monitoring, by a controller, operation of the HVAC system, determining, by the controller, whether power exists at a duct terminal of the at least one IAQ monitor and responsive to a determination that the power exists at the duct terminal of the at least one IAQ monitor, configuring, the at least one IAQ monitor as being installed within a ductwork.
