1. A device for detecting the parameters of an aerosol, in particular in an inhalation therapy device, comprising a. a transmitting means i. which is disposed on a body that at least partially surrounds an aerosol resting area, and ii. which emits radiation into said aerosol resting area through a translucent material;
- b. a first receiving means, i. which is disposed on the body (that at least partially surrounds said aerosol resting area, ii. which is disposed in relation to said transmitting means so as to primarily receive transmission radiation, and iii. which emits a first analysis signal that corresponds to the intensity of the received transmission radiation;
c. a second receiving means, i. which is disposed on the body that at least partially surrounds said aerosol resting area, ii. which is disposed in relation to said transmitting means so as to primarily receive scattered radiation, and iii. which emits a second analysis signal that corresponds to the intensity of the received scattered radiation; and
d. a control means, to which the first and second output signals are supplied and which analyses the first and second output signals in order to determine the parameters of an aerosol in said aerosol resting area.

Abstract
The invention relates to a device for detecting the parameters of an aerosol, in particular in inhalation therapy devices, whereby light is shone through a translucent material but not through a transparent material in a detection region and is detected and analysed by means of two receivers.
