Abstract: An aerosol-generating device is disclosed. The aerosol-generating device of the present disclosure includes a heater configured to heat an aerosol-generating substance, a battery configured to supply electric power to the heater, a sensor disposed adjacent to the battery and configured to output a signal, and a controller. The controller determines the distance between the sensor and the battery based on a change in a signal received from the sensor. When the distance between the sensor and the battery is shorter than a predetermined reference distance, the controller performs control such that supply of electric power from the battery to the heater is interrupted.

Abstract: An aerosol-generating device and an operation method thereof are disclosed. The aerosol-generating device of the disclosure includes a heater, a power supply circuit for supplying power to the heater, a puff sensor, and a controller. The controller controls the power supply circuit such that the heater is heated in a first period during which a puff is detected. Upon determining that the intensity of the puff detected in the first period is equal to or less than a predetermined reference intensity, the controller controls the power supply circuit such that first power is supplied to the heater in a second period subsequent to the first period. Upon determining that the intensity of the puff detected in the first period exceeds the reference intensity, the controller controls the power supply circuit such that second power, which is higher than the first power, is supplied to the heater in the second period.
