a heater configured to heat an aerosol generating material to generate aerosol;
a memory storing a relationship between a plurality of current difference values and a plurality of heater temperature values as a lookup table; and
a controller configured to:
calculate a current flowing through the heater based on a predefined resistance of the heater and power supplied to the heater,
