Integrated device for measuring internal temperature and dust of vehicle

An integrated apparatus for measuring an interior temperature and dust of a vehicle includes: a main body unit provided with a main flow path including an inlet and an outlet configured to receive and discharge air therethrough; a fan motor unit provided in the main body unit and configured to forcibly blow indoor air of the vehicle through the main flow path; a temperature measuring unit configured to measure an internal temperature by air sucked into the main flow path when the fan motor unit is driven; and a dust sensing unit provided with an auxiliary flow path branched from the main flow path, in which the dust sensing unit is configured to allow a portion of the air sucked into the main flow path to flow in the auxiliary flow path to determine a dust concentration in the air sucked into the auxiliary flow path.
