Abstract: An aerosol generating device includes a main body including a main body portion having an accommodation space into which an aerosol-generating article is inserted; a cap detachably coupled to the main body; a cartridge detachably coupled to the main body portion; a first sensor configured to detect whether the cap is attached or detached; a second sensor configured to detect whether the cartridge is attached or detached; a third sensor configured to detect a remaining amount of liquid in the cartridge; and a microcontroller electrically connected to the first sensor, the second sensor, and the third sensor. The microcontroller wakes up when a measurement value detected by the first sensor changes to a preset value or more and determines whether the cap is attached or detached, when it is determined that the cap has been removed from the main body, the microcontroller detects whether the cartridge is detached or not using the second sensor during a preset grace time, but when the microcontroller does not detect attachment or detachment of the cartridge during the grace time, the microcontroller switches to sleep mode when the grace time elapses, and during the sleep mode, the microcontroller wakes up when the measurement value detected by the third sensor changes to a preset value or more, and re-detects whether the cartridge is attached or detached using the second sensor.
