1. A method of monitoring air quality, the method comprising:
receiving, at a centralized processing device and from a plurality of sensors located in a vehicle, signals indicative of values for one or more air quality parameters for air in the vehicle;
assigning, by the centralized processing device, time stamps to each of the values for the one or more air quality parameters;
determining, by the centralized processing device and based on the time stamps, a change in the one or more air quality parameters over a period of time;
comparing, by the centralized processing device, the change in the one or more air quality parameters over the period of time against a threshold value; and
generating, by the centralized processing device, an output based on a determination by the centralized processing device that the change in the one or more air quality parameters is greater than or equal to a threshold value.
