La solution, selon l'invention, porte sur un dispositif d'inhalation comprenant : une unité d'alimentation électrique servant à accumuler et à fournir de l'énergie électrique ; une unité de chauffage destinée à chauffer un matériau de base contenant une source d'aérosol de façon à générer un aérosol ; et une unité de commande servant à commander l'alimentation électrique de l'unité d'alimentation électrique à l'unité de chauffage sur la base d'une condition de chauffage, la condition de chauffage comprenant un profil de chauffage qui représente des informations destinées à définir des variations de transition dans la température cible qui est une valeur cible de température de l'unité de chauffage, et des informations pour définir une période de chauffage représentant une durée pendant laquelle le matériau de base est chauffé et une période de non-chauffage représentant une durée pendant laquelle le matériau de base ne doit pas être chauffé, et l'unité de commande effectue une commande sur l'alimentation électrique de l'unité de chauffage tout en commutant alternativement entre la période de chauffage et la période de non-chauffage de sorte à augmenter la température de l'unité de chauffage à la température cible.
