System for Inexpensive Characterization of Air Pollutants and Inexpensive Reduction of Indoor Dust

摘要

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.
