Abstract

The present teachings relate to an electronic cigarette, and an airflow sensor and a circuit included in the electronic cigarette. The airflow sensor may include a fixed conductive plate, a flexible conductive film, and a spacer located between the conductive plate and the conductive film. When inhaling is from a side of the conductive film, the conductive film moves away from the conductive plate. The circuit may include an acquisition module, a selecting module, and a controlling module. The acquisition module may determine a type of the airflow sensor. The selecting module may determine a voltage value based on the type of the airflow sensor and generate a control command corresponding to the determined voltage value. The controlling module may generate a control signal. The control signal may control whether to heat aerosol forming material included in the electronic cigarette.
