Abstract
A cartridge for an e-vaping device includes an infrared sensor configured to measure infrared radiation emitted by at least a portion of a heating element coupled to a dispensing interface in the cartridge. The field of view of the infrared sensor may encompass an entirety of the heating element. The infrared sensor may be an infrared light emitting diode. The e-vaping device may include control circuitry configured to determine the temperature of the heating element based on sensor data generated by the infrared sensor and control the electrical power supplied to the cartridge based on the temperature of the heating element. The control circuitry may control the electrical power to maintain the temperature of the heating element below a threshold temperature. The control circuitry may determine the heating element temperature based on accessing at least a portion of the sensor data stored at a storage device in the cartridge.
