1. An aerosol generating device comprising:
a liquid storage configured to store an aerosol generating material;
a first residual amount detection sensor and a second residual amount detection sensor respectively arranged on a first portion and a second portion of the liquid storage;
a third residual amount detection sensor and a fourth residual amount detection sensor respectively arranged on a third portion and a fourth portion of the liquid storage, the third portion and the fourth portion being different from the first portion and the second portion; and
a controller configured to:
start measuring a remaining amount of the aerosol generating material when a difference between a first detected value output by the first residual amount detection sensor and a second detected value output by the second residual amount detection sensor is included within a predetermined reference range; and
measure the remaining amount of the aerosol generating material based on the first detected value and the second detected value.
