I wonder if flow cytometry would work? Have a venturi on mild suction, designed to flow a jacket layer around the perimeter, and a laser to detect forward and side scatter. That gives you size and complexity. That plus location, time, wind, and season could probably give you a very useful signal. If not in the home, certainly if the data was sent to central system, a la weather stations.
