    Abstract: An IAQ sensor module includes: a sensor configured to measure an amount of an item in air, the item being one of particulate matter, volatile organic compounds, and carbon dioxide; a minimum module configured to selectively store the amount of the item as a minimum value of the amount when a mitigation device has been on for at least a predetermined period, the mitigation device being configured to decrease the amount of the item in the air when on; a storing module configured to selectively store the minimum value as an initial minimum value; an offset module configured to determine a drift offset for the sensor based on a difference between the minimum value and the initial minimum value; and an adjustment module configured to determine an adjusted amount of the item in the air at the IAQ sensor module based on the amount and the drift offset.

    Abstract: An indoor air quality (IAQ) system for a building includes an IAQ sensor that is located within the building and that is configured to measure an IAQ parameter, the IAQ parameter being one of: a relative humidity (RH) of air; an amount of particulate of at least a predetermined size present in air; an amount of volatile organic compounds (VOCs) present in air; and an amount of carbon dioxide present in air. A mitigation module is configured to: selectively turn on a mitigation device based on a comparison of the IAQ parameter with a first threshold; and selectively turn off the mitigation device based on a comparison of the IAQ parameter with a second threshold. A thresholds module is configured to: set the first and second thresholds to predetermined default values; and selectively adjust at least one of the first and second thresholds.

    Abstract: A condition identification module is configured to, based on output from the at least one of a microphone and a camera, indicate an occurrence of a user having a physical condition. A correlation module is configured to, based on the occurrence of the user having the physical condition and at least one of a temperature of air, a relative humidity of air, an amount of particulate of at least a predetermined size present in air, an amount of VOCs present in air, and an amount of carbon dioxide present in air, selectively identify the presence of a correlation between the occurrence of the user having the physical condition and the at least one of the temperature, the RH, the amount of particulate, the amount of VOCs, and the amount of carbon dioxide.
