Abstract: Disclosed is an aerosol generating device including a heater configured to generate an aerosol by heating an aerosol generating substance; and a controller configured to control a current supplied to the heater without using feedback control such that the heater is heated to a pre-set reference temperature, and when the heater is heated to the reference temperature, control the current by using feedback control such that the heater is further heated from the reference temperature to a target temperature, based on a difference between a temperature of the heater and the target temperature.

Abstract: An aerosol-generating device and an operation method thereof are 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 capacitance sensor including an electrode disposed adjacent to the insertion space, and a controller. The controller sets a unit time for which charging and discharging of the electrode are monitored once, calculates a time for which charging and discharging of the electrode are completely performed once based on the set unit time, and determines whether the stick is inserted into the insertion space based on the calculated time. The unit time exceeds a predetermined period of time for which charging and discharging of the electrode are completely performed once in response to insertion of the stick.

Abstract: An aerosol-generating device and an operation method thereof are disclosed. The aerosol-generating device of the disclosure includes a heater configured to heat an aerosol-generating substance, a puff sensor configured to detect a puff, and a controller configured to process a signal from the puff sensor. The controller determines a first frequency corresponding to a first puff time period and a second frequency corresponding to a second puff time period, which is longer than the first puff time period, filters the signal from the puff sensor based on the first frequency and the second frequency, and adjusts the power supplied to the heater based on the result of filtering. The first frequency is a frequency lower than the second frequency.
