Abstract
A session control system for a device includes at least one processor and a memory coupled to the at least one processor. The memory is configured to store instructions. The at least one processor is configured to execute the instructions to cause the session control system to detect when a session has started, start a session timer, increment a puff variable when an airflow sensor detects that a puff has been taken, monitor the session timer against a time threshold and the puff variable against a puff threshold, and in response to a session threshold being met, end the session. The session timer is configured to measure a length of the session and the puff variable corresponds to a total number of puffs taken.
