Abstract

A gas detection system includes a sensor unit that outputs a voltage corresponding to a concentration of a specific gas, a supply unit, and a control unit. The supply unit is capable of supplying a sample gas and a purge gas to the sensor unit. The control unit controls the supply unit to alternately supply the sample gas and the purge gas to the sensor unit. The control unit acquires a voltage waveform output by the sensor unit and detects a type and concentration of a gas contained in the sample gas, using a multiple regression analysis using characteristics of the voltage waveform as explanatory variables.
