Device for collecting odor data and method for collecting odor data using the same

A method of collecting odor data, the method comprising:

• injecting a gas metered in an amount corresponding to a target concentration for a preset odor intensity into an odor measurement chamber;
• sensing, by internal odor sensors disposed in the odor measurement chamber, an odor of the gas, wherein the internal odor sensors are of different types from each other;
• sensing, by an external odor sensor, the odor of the gas during a process in which the gas injected into the odor measurement chamber sequentially flows through a first gas circulation line connected to an outside of the odor measurement chamber, the external odor sensor, and a second gas circulation line and returns back to the odor measurement chamber;
• and
• collecting, by a controller, data on the odor sensed by the internal odor sensors and the external odor sensor.

A system for collecting odor data, the system comprising:

• an odor measurement chamber comprising a gas injection hole, a discharge hole, and a return hole;
• internal odor sensors disposed in the odor measurement chamber, wherein the internal odor sensors are of different types from each other, and wherein the internal odor sensors are configured to sense an odor of a gas injected into the odor measurement chamber;
• an external odor sensor disposed outside the odor measurement chamber, wherein the external odor sensor is configured to sense the odor of the gas;
• a first gas circulation line having a first end connected to the discharge hole and a second end connected to the external odor sensor;
• a second gas circulation line having a first end connected to the return hole and a second end connected to the external odor sensor;
• and
• a controller configured to collect data on the odor sensed by the internal odor sensors and the external odor sensor.
