【Abstract】 Gas sensors are classified into electrical, optical, electrochemical sensors and the others according to their mechanism of work. The working mechanism and the detecting range and the features of various gas sensors are discusses in the issue. It also discusses the development in discovering new gas elements, making new gas sensors of integrated elements and multifunction, researching the structure and working mechanism of gas sensors. The developing trends of gas detectors on smaller, more intelligent and more common in detected gases, detecting range and detecting ways are put forward in the article.更多还原
