Abstract
A method of and a system for detecting a gas. A histogram of gas sensor outputs in the past is prepared to determine a gas detection threshold value from the histogram. The threshold value is determined, for example, based on the modal sensor output on the histogram. The threshold value is modified based on the width of distribution on the histogram since the width represents the degree of pollution of the background.
