Assignee: HALO SMART SOLUTIONS, INC.
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A device, comprising;
a particle detection sensor 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;
a processor;
a memory storing instructions that, when executed by the processor, cause the processor to:
generate a first sample histogram comprising particle measurement values in each of the plurality of bins, wherein the first sample histogram represents an ambient environment being evaluated and comprises the first and second particle measurement values as received from the particle detection sensor at a first time;
generate a second sample histogram comprising particle measurement values in each of the plurality of bins, wherein the second sample histogram comprises the first and second particle measurement values as received from the particle detection sensor at a second time different from the first time;
determine a distance of a source of a pollutant from the device based upon the first and second sample histograms;
determine, based on a comparison of the first sample histogram with a profile histogram, a match quality value for the presence of the pollutant in the environment;
upon the match quality value meeting or exceeding a threshold match value, generate a detected event notification.
