12. An aerosol-generating device comprising:
an elongated container comprising an inner wall and an outer wall, wherein the inner wall defines an insert space configured to accommodate insertion of an aerosol-generating member, and wherein a chamber configured to store liquid is defined between the inner wall and the outer wall;
a wick disposed at an end of the insert space;
a heater configured to heat the wick;
a passage formed between the insert space and the wick; and
an infrared sensor disposed adjacent to the container and configured to emit infrared light through the inner wall and outer wall and detect a value based on the infrared light reflected by the aerosol-generating member inserted in the insert space.
