Claim 27:
28. A computer-implemented method, comprising:
receiving, by a computing device, first and second particle measurement values as received from a particle detection sensor, wherein the particle detection sensor 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 measures a first particle measurement value for particles of a first size, and wherein a second bin of the plurality of bins measures a second particle measurement value for particles of a second size, wherein the second size is larger than the first size, wherein the first and second particle measurement values of the first sample histogram are measured at a plurality of intervals over a time span;
generate, by the computing device based on the received first and second particle measurement values, a first sample histogram comprising an array of particle measurement values in each of the plurality of bins, wherein the first sample histogram represents an ambient environment being evaluated;
determine a distance of a source of the pollutant from the device based solely upon the first and second particle measurement values over the time span;
determine, based on a comparison of the first sample histogram with a profile histogram, a match quality value for the presence of a pollutant in the environment; and
upon the match quality value meeting or exceeding a threshold match value, generate a detected event notification.
