Abstract

The present invention relates to an aerosol-generating device for heating an aerosol-forming substrate that is capable to form an inhalable aerosol when heated. The device comprises a cavity for removably receiving at least a portion of an aerosol-generating article comprising the aerosol-forming substrate to be heated. The device further comprises an electrical heating arrangement comprising an electronic circuitry and a heating element operatively coupled to the electronic circuitry for heating the aerosol-forming substrate when the aerosol-generating article is received in the cavity. In addition, the device comprises a controller comprising a temperature sensor configured to output a signal indicative of the temperature or a temperature increase of at least one portion of the electronic circuitry during operation of the heating arrangement. The controller is configured to detect the presence, absence, or displacement of the article in the cavity in response to the signal indicating that the temperature or the temperature increase has breached a predefined temperature threshold or a predefined temperature increase threshold, respectively. The invention further relates to an aerosol-generating system comprising such a device as well to a method for detecting the presence, absence, or displacement of an aerosol-generating article in a cavity of an aerosol-generating device.
