Aerosol generating apparatus for detecting insertion of aerosol generating article and operation method thereof

An aerosol generating system comprising:

• an aerosol generating device including formed therein a first accommodation space including a susceptor and having an aerosol generating article inserted therein;
• and
• a cradle including formed therein a second accommodation space having the aerosol generating device accommodated therein,
• wherein the aerosol generating device includes:
• a battery charged by power received from the cradle while the aerosol generating device is accommodated in the second accommodation space;
• an induction coil configured to form a magnetic field within the first accommodation space by receiving power from the battery;
• and
• a controller electrically connected to the induction coil,
• wherein the controller is configured to:
• measure an amplitude of a voltage applied to the induction coil;
• when the measured amplitude of the voltage is less than or equal to a predefined value, determine that the aerosol generating article is inserted into the first accommodation space;
• and
• when determining that the aerosol generating article is inserted into the first accommodation space, heat the susceptor by controlling the induction coil to form the magnetic field.
