1. An integrated apparatus for measuring internal temperature and dust of a vehicle, the integrated apparatus comprising:
a main body provided with a main flow path including an inlet and an outlet to receive air through the inlet and to discharge the air through the outlet;
a fan motor provided in the main body and configured to forcibly blow indoor air of the vehicle through the main flow path;
a temperature sensor configured to measure the internal temperature through the air drawn into the main flow path, as the fan motor is driven; and
a dust sensor provided with a subsidiary flow path branching off from the main flow path, wherein the dust sensor is configured to allow a part of the air drawn into the main flow path to flow in the subsidiary flow path to determine a dust concentration in the air drawn into the subsidiary flow path,
wherein the subsidiary flow path is formed in a “U” shape, and
wherein a light outlet hole is formed at a bottom of the U-shaped subsidiary flow path and a light of a light source radiates through the light outlet hole, after the light passes over a light receiver.
