System and method of obtaining smoking topography data

A smoking topography circuit of an electronic smoking article, the circuit comprising:

• at least one sensor configured to detect user interaction with the smoking article;
• a battery configured to supply power to the smoking article;
• a processor configured to detect a smoking event based an output of the at least one sensor, collect data associated with the smoking event, arrange the data in a pattern that defines the smoking event by at least a shift in battery voltage;
• and
• memory configured to record the data pattern in a structured format.

A method of generating smoking topography data for an electronic aerosol smoking article including at least a battery, an aerosol generator including a heating element to produce a smoke stream, and a processor, the method comprising:

• determining an occurrence of a smoking event through at least one sensor that measures user interaction with the smoking article;
• capturing a battery voltage at a start and an end of a smoking event;
• and
• generating a data structure that defines the smoking event with respect to a change in battery voltage at the start and end of the smoking event.

The method of claim 26, comprising:

• generating a second interrupt when the puff release event is detected;
• and
• stopping the first timer upon generation of the second interrupt;
• and
• starting a second timer upon generation of the second interrupt to measure a duration until a next puff start event.
