Abstract
An aerosol delivery device includes at least one housing, a heating element, a sensor, and a microprocessor coupled to the heating element and the sensor. The at least one housing encloses a reservoir configured to retain an aerosol precursor composition. The sensor is configured to produce measurements of differential pressure between an ambient atmospheric pressure and a pressure caused by airflow through at least a portion of the aerosol delivery device. The sensor is also configured to convert the measurements of differential pressure to corresponding electrical signals. The microprocessor is configured to receive the corresponding electrical signals and operate in an active mode only in an instance in which the differential pressure is at least a 10 threshold differential pressure. The microprocessor in the active mode is configured to control the heating element to activate and vaporize components of the aerosol precursor composition.
