1. An apparatus, comprising: a housing including an interior area; at least one shelf positioned within the interior area of the housing; a door movable between a closed position that prevents access to the interior area of the housing and an open position that enables access to the interior area of the housing; a locking mechanism associated with the door and configured to engage or disengage the door relative to the closed position; an input component configured to receive unique identifiers; at least one weight sensor associated with the at least one shelf, the at least one weight sensor operable to measure a weight of one or more items positioned on the at least one shelf; an imaging device positioned proximate the door of the housing; one or more processors; and a memory storing program instructions that when executed by the one or more processors cause the one or more processors to at least: receive, from the input component, a unique identifier associated with a user; and in response to receipt of the unique identifier: initiate a session; instruct the locking mechanism to disengage the door such that the door is movable from the closed position to the open position; detect a movement of the door from the closed position to the open position; responsive to disengaging the door by the locking mechanism, instruct the at least one weight sensor to detect weight sensor data during the session; detect a movement of the door from the open position to the closed position; instruct the locking mechanism to engage the door such that the door is retained in the closed position; responsive to engaging the door by the locking mechanism, instruct the at least one weight sensor to stop detecting weight sensor data during the session; complete the session; and responsive to completion of the session, process the weight sensor data detected by the at least one weight sensor to determine one or more events during the session.
