Abstract
A device for detecting the presence of pollen in the air, including a measuring chamber isolated from external light, an arrangement configured to drive an air flow through the measuring chamber, and a light source emitting a light beam in a direction of propagation through the air flow, into the measuring chamber. The device includes at least four photosensitive sensors configured to measure the luminous flux diffused by the illuminated air flow, in four different directions, a clock, at least two meteorological sensors, and at least one computer capable of determining the nature of a pollen particle present in the air from the data measured by the photosensitive sensors, the clock and the meteorological sensors.
