Abstract
Embodiments of a sensor device, method and system employ one or more particle detection sensors to collect particle measurement values in a plurality of particle bins collecting particles of different sizes, generate a histogram representing the particle measurement values and determine based on a comparison of the histogram with a profile histogram for a pollutant, a match quality indicative of whether the pollutant is present in the environment. In various embodiments, a location of a pollutant is also determined according to the determined match quality.
