Abstract:

The electronic nose is a high-tech product developed to simulate the olfactory organs of animals. As the core component of the electronic nose, the gas sensor converts information such as composition and concentration into electrical signal by reacting with the gas to be measured. The sensors can realize the fast, sensitive and real-time detection of harmful gases in the environment. This article introduces the basic principles and application fields of semiconductor, electrochemical, and infrared gas sensors, focusing on the research progress of gas sensors in recent years, and prospects for their future development.

Key words: Gas sensing, Semiconductor sensor, Electrochemical sensor, Infrared gas sensor
