Abstract

An aerosol generating device and a controlling method thereof are provided. An aerosol generating device includes: a battery configured to supply power for generating an aerosol from an aerosol generating material; a converter configured to convert a supply voltage from the battery into a constant voltage of a predetermined level; a heater configured to heat the aerosol generating material using the supply voltage; a detection circuit configured to detect a change in resistance of the heater by applying the constant voltage output from the converter and performing a current sensing on the heater with a resistance value; and a controller configured to control the heater for generating the aerosol by switching between a monitoring mode for performing the detection of the change in the resistance of the heater using the constant voltage and a heating mode for heating the heater using the supply voltage.
