Title:
AIR QUALITY DETERMINING SYSTEM, AIR QUALITY DETERMINING METHOD, AND SENSOR MODULE
Document Type and Number:
WIPO Patent Application WO/2022/114158
Kind Code:
A1
Abstract:
The present disclosure addresses the problem of suppressing a deterioration in the determination accuracy of the air quality state. An air quality determining method according to the present disclosure includes a temperature control step, an acquisition step, a determination step, and an output step. In the temperature control step, the temperature of a sensitive portion (2) which is exposed to a sample gas is controlled to vary in accordance with a temperature variation pattern including at least one each of a rising temperature period in which the temperature of the sensitive portion (2) rises, and a falling temperature period in which the temperature of the sensitive portion (2) falls. In the acquisition step, an electrical characteristic value of the sensitive portion (2) exposed to the sample gas is acquired. In the determination step, a trained model (MD1) for determining the air quality state of the sample gas is used to determine the air quality state of the sample gas on the basis of a variation in the electrical characteristic value. In the output step, the determination result obtained in the determination step is output.
