Apparatus for generation aerosol from an aerosolizable medium, an article of aerosolizable medium and a method of operating an aerosol generating apparatus

An apparatus for generating aerosol from an aerosolizable medium, the apparatus comprising:

• a chamber for receiving an article, the article comprising:
• an aerosolizable medium, and
• an indicia;
• and
• an optical sensor arrangement for reading the indicia, wherein a surface of the optical sensor arrangement is positioned to contact the article received within the chamber in use.

An article comprising:

• an aerosolizable medium;
• and
• an indicia;
• wherein at least a portion of an outer surface of the article is compressible and configured to contact an optical sensor arrangement of an apparatus, the apparatus arranged to receive the article and to aerosolize the aerosolizable medium of the article, during insertion of the article into the apparatus for generating aerosol from an aerosolizable medium.

An apparatus for generating aerosol from an aerosolizable medium, the apparatus comprising:

• a chamber for receiving an article, the article comprising an aerosolizable medium and an indicia, wherein the chamber defines a longitudinal axis;
• and
• a sensor for reading the indicia received within the chamber in use, wherein the sensor is spaced from the chamber to define a gap between the sensor and the article received within the chamber in use, wherein the sensor is spaced from the chamber in a direction not parallel to the longitudinal axis,
• wherein the apparatus is configured to provide an airflow in a direction from the sensor to the chamber.
