Abstract
An aerosol generating device, including an inductance channel, includes: a heater configured to generate an aerosol by heating a cigarette; a cigarette insertion space into which the cigarette is inserted; a first inductance channel; a second inductance channel; and a controller configured to generate a control signal by using information received from the first inductance channel and the second inductance channel, wherein the controller measures, when an amount of a change in frequency of current flowing through the first inductance channel exceeds a first reference value due to an object adjacent to the cigarette insertion space, an amount of a change in frequency of current flowing through the second inductance channel and controls, when the measured amount of the change in frequency of the current is less than a second reference value, a power supply to the heater to be started.
