1. An aerosol generating device comprising:
a cartomizer comprising:
a cartridge configured to store an aerosol generating material; and
an atomizer configured to vaporize the aerosol generating material;
an accommodation space accommodating the cartomizer,
at least one pair of electrodes arranged in positions contacting one side of the cartridge, the electrodes are arranged on an inner surface of the accommodation space;
at least one pair of bottom electrodes arranged on a bottom surface of the cartridge;
a sensor configured to measure capacitance of the electrodes and the bottom electrodes; and
a controller configured to:
detect the remaining amount of the aerosol generating material based on the capacitance of the electrodes; and
correct the detected remaining amount of the aerosol generating material according to a tilt of the cartridge detected based on the capacitance of the bottom electrodes.
