7. A device comprising:
a dispensing interface configured to hold a pre-vapor formulation;
a heating element coupled to the dispensing interface, the heating element configured to heat the pre-vapor formulation held within the dispensing interface, the heating element extending along an outer surface of the dispensing interface;
a conductive element extending through an interior of the dispensing interface, wherein the dispensing interface is configured to establish a bridge electrical circuit between the heating element and the conductive element when an amount of pre-vapor formulation held within the dispensing interface is greater than or equal to a threshold amount; and
a sensor wire coupled to the dispensing interface separately from the conductive element and the heating element, the sensor wire being configured to carry an electrical signal propagating through the bridge electrical circuit.
