Claim 13:
14. A system, comprising:
a plurality of networked particle detection sensors, each of which is operable to detect a range of particle measurements in each of a plurality of bins, wherein a first bin of the plurality of bins for each of the plurality of particle detection sensors measures a first particle measurement value for particles of a first size, and wherein a second bin of the plurality of bins for each of the plurality of particle detection sensors measures a second particle measurement value for particles of a second size, wherein the second size is larger than the first size;
a processor;
a memory storing instructions that, when executed by the processor, cause the processor to:
generate a series of first sample histograms comprising an array of particle measurement values in each of the plurality of bins for each of the plurality of particle detection sensors, wherein the series of first sample histograms represents an ambient environment being evaluated, wherein the array for each of the plurality of particle detection sensors comprises the first and second particle measurement values as received from each of the plurality of particle detection sensors;
determine a distance of each of the plurality of particle detection sensors to a source of a pollutant within the environment based upon sensor measurement values consisting of the particle measurement values in each of the plurality of bins over a time span;
determine, based on a comparison of the series of first sample histograms with a profile histogram, a match quality value for each of the plurality of particle detection sensors for the presence of the pollutant in the environment; and
upon the match quality value for at least one of the plurality of particle detection sensors meeting or exceeding a threshold match value, generate a detected event notification.
