  • Patent number: 11944124
    Abstract: An aerosol generating device may include a heater configured to heat an aerosol generating material, a battery configured to supply power to the heater, and a controller. In addition, the aerosol generating device may further include a user input detection sensor configured to receive a user's input and a pressure detection sensor configured to sense pressure. The controller may, in response to the user's input being sensed by using the user input detection sensor, obtain an initial pressure sensing value by using the pressure detection sensor. In addition, the controller may determine a reference pressure value based on the initial pressure sensing value and determine whether a puff of the aerosol generating device has occurred based on the reference pressure value.
