Claim 15:
16. A method of controlling an aerosol-generating device, the aerosol-generating device comprising a heating element in an air flow passage extending in a first direction, the method comprising:
measuring 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;
measuring a second temperature at a second position along the air flow passage, wherein the second position is spaced apart in the first direction from the first position, 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;
measuring 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
controlling an operational parameter of the device, based on the measured first temperature, the measured second temperature, and the measured third temperature, the operational parameter being a parameter that affects operation of one or more components of the aerosol-generating device.
