    Abstract: A method of counting the number of puffs using an aerosol generating device is disclosed. The may include obtaining a first start time which is a time when a pressure measured by a sensor included in the aerosol generating device decreases below a first reference pressure value; obtaining a first end time which is a time when the pressure measured by the sensor reaches the first reference pressure value after the first start time; determining whether a first period, which is a period between the first end time and the first start time, is longer than or equal to a first reference period; and increase the number of puffs by one based on the first period being longer than or equal to the first reference period.

    Abstract: An aerosol generating device includes: a liquid storage configured to store an aerosol generating material; a first residual amount detection sensor and a second residual amount detection sensor respectively arranged on a first inner surface and a second inner surface that face each other among inner surfaces of the liquid storage; a third residual amount detection sensor and a fourth residual amount detection sensor respectively arranged on a third inner surface and a fourth inner surface of the liquid storage that face each other and are different from the first inner surface and the second inner surface of the liquid storage; and a controller configured to measure a remaining amount of the aerosol generating material based on a first detected value output by the first residual amount detection sensor and a second detected value output by the second residual amount detection sensor.

    Abstract: An aerosol generating device includes: a cartridge including a liquid storage and an atomizer; and a main body including a battery, a puff sensor, and a controller configured to perform pulse width modulation (PWM) control for supplying power from the battery to the atomizer, wherein the controller performs the PWM control at a first duty ratio during a puff period and performs the PWM control at a second duty ratio lower than the first duty ratio during a non-puff period between puff periods.

    Abstract: An aerosol generating device includes: a first cartridge configured to accommodate a first material and including a delivery hole that is configured to deliver an aerosol generated from the first material; a second cartridge including a plurality of chambers that are each configured to accommodate a second material through which the aerosol delivered from the first cartridge passes and is discharged to the outside, wherein a position of the second cartridge with respect to the first cartridge is changeable so that at least one of the plurality of chambers corresponds to the delivery hole; a position sensor configured to generate a signal by detecting a position of at least one of the plurality of chambers with respect to the delivery hole; and a controller configured to identify a usage chamber based on the signal of the position sensor.
