Aerosol generating device

Abstract

An aerosol generating device includes a body including an insertion space to accommodate an aerosol generating article, a heater configured to heat the aerosol generating article accommodated in the insertion space, an inductive sensor configured to generate a sensing value according to a distance to a magnetic object, and a controller electrically connected to the inductive sensor and configured to determine a degree of proximity of the magnetic object to the body by comparing the sensing value with a reference value as a reference for determination, wherein the controller is further configured to calibrate the reference value based on the sensing value such that the reference value maintains a certain difference from the sensing value.
