1. An aerosol generating device comprising:
a first heater configured to heat a liquid composition accommodated in a liquid storage of a vaporizer;
a puff sensor configured to detect a pressure change in the aerosol generating device; and
a controller configured to:
determine states of a plurality of sections constituting a puff pattern representing a pressure change over time, based on a signal received from the puff sensor, and
control an operation of the first heater, based on the states of the plurality of sections,
wherein the plurality of sections include a first section and a second section following the first section, and the controller is further configured to start the operation of the first heater based on the first section being determined as a pressure maintaining state and the second section being determined as a pressure falling state.
