1. An aerosol-generating device comprising:
a cigarette insertion detection sensor configured to detect insertion of a cigarette into an accommodation space of the aerosol-generating device;
a heater configured to heat the cigarette inserted in the accommodation space;
at least one temperature sensor configured to measure temperatures of at least two locations inside the aerosol-generating device, wherein the at least one temperature sensor includes at least two of a first thermistor placed adjacent to a front surface or a rear surface of battery configured to supply power to the heater, a second thermistor placed between the heater and the battery, or a temperature/humidity sensor placed near a lower surface of the battery; and
a controller configured to determine whether the aerosol-generating device is in an overheated state based on the temperatures measured by the at least two of the first thermistor, the second thermistor, and the temperature/humidity sensor when the insertion of the cigarette is detected by the cigarette insertion detection sensor, and control the heater to suspend a heating operation until the overheated state is finished based on the overheated state being detected.
