    摘要: A gas detection device and a method for detecting a gas where gas information including concentrations of gas components in a mixed gas, concentration, presence of specific gas components and the like is detected by measuring, e.g., the output voltages of a plurality of gas sensors having different gas selectivities. The gas selectivities, as a characteristic constant of the specific gas sensor, was previously determined. The measured output voltages and gas selectivities are then used for solving plural simultaneous equations for gas concentrations.
