1. An aerosol delivery device comprising:
a power source configured to provide an output voltage;
an aerosol production component powerable to produce an aerosol from an aerosol precursor composition;
a sensor configured to produce measurements of atmospheric air pressure in an air flow path through at least a portion of the aerosol delivery device;
a switch coupled to and between the power source and the aerosol production component; and
processing circuitry coupled to the sensor and the switch, and configured to at least: determine a difference between the measurements of atmospheric air pressure from the sensor, and a reference atmospheric air pressure; and only when the difference is at least a threshold difference,
output a signal to cause the switch to switchably connect and disconnect the output voltage to the aerosol production component to power the aerosol production component for an aerosol-production time period, the switch caused to switchably connect and disconnect the output voltage to adjust power provided to the aerosol production component to a power target that is variable according to a predetermined relationship between the difference and the power target,
wherein the threshold difference is set to reflect a minimum deviation from the reference atmospheric air pressure caused by a puff action of using the aerosol delivery device by a user.
