Abstract

An aerosol generating device includes an accommodation space into which an aerosol generating article is inserted, a heater configured to heat the aerosol generating article, an insertion detection sensor configured to detect whether the aerosol generating article has been inserted into the accommodation space, and a controller configured to provide a user with a notification through an output unit when it is detected that the aerosol generating article inserted into the accommodation space has been moved from the accommodation space through the insertion detection sensor during a heating operation of the heater. The heater maintains the heating operation of heating the aerosol generating article even while the notification is being provided.
