1. A method of sensing temperature of air in a passenger area of a fuselage, the method comprising:
blowing primary air through an air distribution inlet via an environmental control system;
drawing secondary air from the passenger area of the fuselage into a cabin air inlet, wherein the cabin air inlet is coupled to the air distribution inlet through a duct and the secondary air is passively drawn into the cabin air inlet and to the duct due to a pressure difference present in the duct; and
sensing, by a temperature sensor coupled to the duct and positioned downstream of the cabin air inlet along an airflow path of the secondary air, a temperature of the secondary air drawn in through the cabin air inlet and flowing through the duct,
wherein the duct comprises:
a plurality of barrels positioned downstream of the air distribution inlet and the temperature sensor, within which the primary air mixes with the secondary air, and
a plurality of nozzles disposed within the duct, coupled to the air distribution inlet, and configured to accelerate the primary air before the primary air enters the plurality of barrels.
