Device for measuring odor and method for measuring odor using the same

A method of measuring an odor, the method comprising:

• causing air containing the odor to flow to a flow guide pipe connected between an inlet and an outlet of a prechamber;
• measuring, by a first sensor mounted to the inlet and a second sensor mounted to the outlet, a temperature and a humidity of the air;
• controlling, by a controller, a first temperature/humidity controller mounted to the prechamber to perform a heating operation or a cooling operation based on the temperature and the humidity of the air measured by each of the first sensor and the second sensor;
• adjusting the temperature and the humidity of the air flowing through the flow guide pipe to reference values through the heating operation or the cooling operation of the first temperature/humidity controller, wherein the first temperature/humidity controller comprises:
• a first heater mounted to the prechamber, the first heater being configured to heat the air flowing through the flow guide pipe in order to adjust the temperature and the humidity of the air;
• and
• a first cooler mounted to the prechamber, the first cooler being configured to cool the air flowing through the flow guide pipe in order to adjust the temperature and the humidity of the air;
• supplying the air adjusted in the temperature and the humidity to an interior of an odor sensor chamber connected to the outlet;
• and
• sensing, by an odor sensor mounted in the odor sensor chamber, the odor contained in the air introduced into the odor sensor chamber.

A device for measuring an odor, the device comprising:

• a prechamber comprising an inlet and an outlet provided in respective end portions thereof;
• a flow guide pipe disposed in the prechamber and connected between the inlet and the outlet in a predetermined pattern to allow air containing the odor to flow therethrough;
• a first sensor mounted to the inlet, the first sensor being configured to measure a temperature and a humidity of the air entering the flow guide pipe;
• a second sensor mounted to the outlet, the second sensor being configured to measure the temperature and the humidity of the air discharged from the flow guide pipe;
• a first temperature/humidity controller mounted to the prechamber, the first temperature/humidity controller being configured to adjust the temperature and the humidity of the air flowing through the flow guide pipe;
• an odor sensor chamber connected to the outlet via a connection pipe;
• and
• an odor sensor mounted in the odor sensor chamber, the odor sensor being configured to sense the odor contained in the air discharged from the flow guide pipe,
• wherein the predetermined pattern of the flow guide pipe connected between the inlet and the outlet is a helical pattern, a zigzag pattern, or a spiral pattern in order to secure a heating time or a cooling time for adjustment of the temperature and the humidity of the air.
