Aerosol generating device and system including the same

Abstract

An aerosol-generating device and a system including the same are disclosed. The aerosol-generating device of the disclosure includes an insertion space, a heater for heating a stick, a stick detection sensor, a display, and a controller. The stick detection sensor includes a first inductance channel and a second inductance channel disposed so as to respectively correspond to a first region and a second region of the insertion space. The controller determines the type of stick based on at least one of a signal corresponding to the first inductance channel or a signal corresponding to the second inductance channel. When the determined type of stick is the same as a predetermined type, the controller supplies power to the heater, and when the determined type of stick is different from the predetermined type, the controller outputs a screen corresponding to the determined type of stick on the display.
