System for monitoring and controlling indoor air quality

An air quality management controller configured to interface with pre-existing HVAC hardware or electrical components to power a HVAC fan or air exchanger to an on position or an off position and for wireless connection to one or more electronic devices or air quality sensors, said air quality management controller comprising one or more sensors for measuring air quality or levels of air contaminants and being operatively connected to one or more components of a HVAC system which has or uses an ultraviolet light (UV) light source as part of a light activated air filtration system, said air quality management controller configured to monitor and interact with a HVAC system control unit based on threshold values set relating to air quality of or levels of containments in a predetermined area, said air quality management controller configured to control at least operation of said UV light source, determine or monitor life cycle or operational status of said UV light source, and to move air to interact with at least said light activated air filtration systems based on said monitoring of said predetermined area, said air quality management controller comprising a zero point crossing detector which detects when power is on or off operatively connected to and sending information to a central processing unit (CPU), said CPU configured to monitor said zero point detector information through an interrupt, wherein activity is stopped if a power stoppage is detected and the time of said power stoppage is recorded;

• said air quality management controller further configured to communicate alert levels or other information relating to one or more functions of said HVAC system or said air quality management controller to one or more electronic devices or networks.

A method of managing indoor air quality within a predetermined area comprising:

• monitoring a predetermined area for levels of air contaminates;
• determining if said predetermined area is in need of air quality management based on detected levels of contaminants within said predetermined area;
• using an air quality management controller interfaced with pre-existing HVAC hardware or electrical components to activate a HVAC fan or air exchanger independently of activation of a said HVAC fan or air exchanger through a HVAC control unit, said air quality management controller comprising one or more sensors for measuring air quality or levels of air contaminants and being operatively connected to one or more components of a HVAC system which has or uses an ultraviolet light (UV) light source as part of a light activated air filtration system, said air quality management controller configured to monitor and interact with a HVAC system control unit based on threshold values set relating to air quality of or levels of contaminants in a predetermined area, said air quality management controller configured to control at least operation of said UV light source, determine or monitor life cycle or operational status of said UV light source, and to move air to interact with at least said light activated air filtration systems based on said monitoring of said predetermined area, said air quality management controller comprising a zero point crossing detector which detects when power is on or off operatively connected to and sending information to a central processing unit (CPU), said CPU configured to monitor said zero point detector information through an interrupt, wherein activity is stopped if a power stoppage is detected and the time of said power stoppage is recorded;
• said air quality management controller further configured to communicate alert levels or other information relating to one or more functions of said HVAC system or said air quality management controller to one or more electronic devices or networks.
