Abstract

A method of monitoring user puff activity of an aerosol-generating system (1, 100) comprising a heating element (2a, 102a) for generating an aerosol from an aerosol-forming material is described. The method includes controlling a power operation of the heating element at regular time intervals for maintaining a target temperature by switching a power supply from the power source (4, 104) to the heating element (2a, 102a) between a high power and a low power, calculating a first value indicative of the power operation over a first consecutive set of the time intervals, and a second value indicative of the power operation over a second consecutive set of the time intervals starting after the first consecutive set, and determining that a puff has either started or ended if an absolute difference between the first value and the second value is greater than a predetermined threshold.
