1. An aerosol generating device comprising:
a housing including an opening for receiving a cigarette including a susceptor;
an induction coil arranged around the opening;
a controller arranged on a printed circuit board in the housing, the controller being configured to control a battery to supply power to the induction coil;
a battery temperature sensor sensing a battery temperature of the battery; and
a temperature sensor connected to the printed circuit board and configured to sense a temperature of a point adjacent to the opening,
wherein the controller is configured to obtain a susceptor temperature of the susceptor, and detect abnormal operation of the aerosol generating device based on at least one temperature of the battery temperature sensed by the battery temperature sensor, the temperature sensed by the temperature sensor, and the susceptor temperature of the susceptor.
