Claim 0:
1. An aerosol-generating device, comprising:
an air inlet;
an air outlet;
an air flow passage extending in a first direction between the air inlet and the air outlet;
a heating element in the air flow passage;
a first temperature sensor configured to measure a first temperature at a first position along the air flow passage, wherein the first position is a position at the heating element and the first temperature is a temperature of the heating element at the first position;
a second temperature sensor spaced apart in the first direction from the first sensor configured to measure a second temperature at a second position along the air flow passage, wherein the second position is a position downstream of the heating element and the second temperature is an ambient temperature of the air flow passage at the second position;
a third temperature sensor configured to measure a third temperature at a third position along the air flow passage, wherein the third position is a position upstream of the heating element and the third temperature is an ambient temperature of the air flow passage at the third position; and
a controller configured to control an operational parameter of the aerosol-generating device based on the measured first temperature, the measured second temperature, and the measured third temperature.
