Abstract
An electronic cigarette with a sensor assembly in an isolated and protected location includes a heating member and a cigarette holder having an air suction port opened to the air outside. The sensor assembly includes an inductive chamber. An open end of the inductive chamber is in air communication with the air suction port. The heating member is arranged outside of the inductive chamber. Inhalations on the electronic cigarette cause decrease of air pressure in the inductive chamber, the resulting reduced air pressure being sensed by the sensor assembly, which is located in the inductive chamber.
