Odor measurement device, control device, and odor determination method

An odor measurement device comprising:

• a sensor having an adsorption film that adsorbs an odorous substance and outputting a signal corresponding to adsorption of the odorous substance on the adsorption film;
• a housing chamber that houses the sensor;
• a first pump configured to supply a first gas containing an odorous substance to the housing chamber;
• a second pump configured to supply a second gas for desorbing the odorous substance from the adsorption film to the housing chamber;
• and
• a control device including:
• a determination unit configured to measure the odorous substance on the basis of information on an output signal of the sensor in a desorption process in which the odorous substance is desorbed from the adsorption film, and
• a control unit capable of sequentially executing a first mode in which the first gas is supplied to the housing chamber and a second mode in which the second gas is supplied to the housing chamber and the odorous substance is measured by the determination unit.
