L'invention concerne un système de génération d'aérosol qui utilise un matériau de base contenant une source d'aérosol et/ou une source d'arôme pour générer un aérosol à inhaler par l'utilisateur, le système de génération d'aérosol comprenant une unité de détection d'informations de corps vivant qui détecte des informations de corps vivant relatives à l'utilisateur et une unité de commande qui commande le fonctionnement de l'unité de détection d'informations de corps vivant. L'unité de commande commande la fréquence de détection des informations de corps vivant par l'unité de détection d'informations de corps vivant.
