## Abstract

An aerosol-generating system (50) has an optical sensor (23) disposed on a portion of an exterior surface of the aerosol-generating system. The optical sensor is configured to output sensor data. A controller (29) is operably coupled to the optical sensor. The controller is configured to manipulate one or more operating parameters of an aerosolizer element of the aerosol-generating system based on the optical sensor data.
