The invention describes
software (including mathematical models implemented in
software) and related electronic circuits that can be used to combine data from local, inexpensive dust sensors (particle counters) with Internet-available rich data on pollutants, weather, optional household devices, sensors, and appliances to create a rich picture of the
local environment, shape that environment through non-trivial control of said household appliances and ventilation systems to reduce buildup of household dust on surfaces or reduce sensitive individuals'
exposure to specific pollutants, and monitor individuals'
exposure to pollutants. The
software might live in a smartphone (such as the inventors' iPhone prototype), related hardware devices (such as a
pollution sensor communicating via
bluetooth with the smartphone) or in heating / cooling
control system such as a common household
thermostat. In particular, advanced control of windows or inexpensive air filters within a common
forced air climate system to mitigate
air pollution inexpensively are envisioned.
