More Information
Summary:An exhaled gas detector includes: a gas detection element configured to measure a specific gas; and an analysis unit configured to analyze a signal output from the gas detection element. The gas detection element measures the specific gas in an exhalation of non-drinking time and generates a first reference signal value. The analysis unit calculates a first threshold value on the basis of the first reference signal value. The gas detection element measures the specific gas in an inspection gas and generates a first measurement signal value. The analysis unit determines that the inspection gas is identified with an exhalation of a person by determining that the first measurement signal value has exceeded the first threshold value.
