Abstract: An aerosol-generating device is disclosed. The aerosol-generating device of the disclosure includes a housing having an insertion space defined therein, a heater configured to heat a stick inserted into the insertion space, a puff sensor configured to detect a puff, a memory configured to store a temperature profile, and a controller. The controller determines, based on the interval between puffs detected in a first period among a plurality of periods in which the stick is heated, a setting value for a second period, which is a period after the first period among the plurality of periods. The controller adjusts power supplied to the heater in the second period based on the determined setting value. The setting value includes at least one of a target temperature of the heater or a heating time period.
