WARNING DETECTOR FOR WARNING OF EXCESSIVELY HIGH POLLUTION OF THE AIR WITH PARTICLES AND, IN PARTICULAR, VIRUSES OF A CERTAIN SIZE

摘要

The invention relates to a warning detector for warning of excessively high pollution of the air with particles and, in particular, viruses of a certain size, wherein the warning detector comprises a sensor unit designed to determine a concentration of vibration-fragmentable particles of a certain target diameter in the air by determination of a difference between a first light scatter at a first sample of the air and a second light scatter at a second sample of the air, wherein the particles in the first sample are uninfluenced and the particles in the second sample have been fragmented by a vibration, and wherein the warning detector comprises a reporting unit designed to report the concentration in the air with the particles when the concentration of a predetermined threshold has been reached.
