1. An aerosol generating device comprising:
a heater configured to heat an aerosol generating material;
a battery configured to supply power to the heater;
a user input detection sensor configured to receive an input of a user;
a pressure detection sensor configured to sense pressure; and
a controller,
wherein the controller is configured to:
in response to the input of the user being sensed by using the user input detection sensor, obtain an initial pressure sensing value by using the pressure detection sensor; and
determine whether a puff of the aerosol generating device has occurred based on the initial pressure sensing value.
