Abstract
An aerosol-generating device is disclosed. The aerosol-generating device includes a first container accommodating an aerosol-generating substance, a heater heating the aerosol-generating substance, a second container configured to be rotatable and including chambers, a rotation detection sensor sensing rotation of the second container, and a controller. The controller determines any one of the chambers to be an application chamber through which an aerosol passes based on a signal received from the rotation detection sensor, and determines usage of a chamber determined to be the application chamber. The heater is heated to a first temperature or higher when the usage is equal to or greater than a first reference and less than a second reference, and is heated to a second temperature or higher when the usage is equal to or greater than the second reference and less than a third reference. The second temperature is higher than the first temperature.
