1. A cartridge for an e-vaping device, the cartridge comprising:
a reservoir including a pre-vapor formulation, the reservoir defining a central channel;
a dispensing interface within the central channel and configured to draw the pre-vapor formulation from the reservoir;
a heating element coupled to the dispensing interface, the heating element configured to heat the drawn pre-vapor formulation to generate a vapor;
a gasket adjacent an end of the reservoir; and
an infrared sensor within the central channel and coupled to the gasket, the infrared sensor configured to measure a temperature of at least a portion of the heating element within a field of view, the field of view directed to the central channel.
