Gas sensors come in a wide variety of types and are widely used

Among the gas sensors currently in use, there are mainly four categories: semiconductor, electrochemical, catalytic combustion, and infrared. Their working principles are different, and their functional characteristics each have their own advantages.

Semiconductor gas sensors have a wide range of applications, are easy to use, and are widely applied in fields such as household gas detection and smart home appliances. They are currently the most widely used type of gas sensors.

Electrochemical gas sensors are highly suitable for detecting low-concentration toxic gases, as well as non-toxic gases such as oxygen and alcohol. Currently, they are mainly applied in various industrial fields and road traffic safety detection areas.

Catalytic combustion gas sensors are suitable for the detection of combustible gases and are mainly used in the coal mining field to detect gas.

Infrared gas sensors are suitable for detecting gases such as methane and carbon dioxide. In current practical applications, carbon dioxide products are more commonly used and have a wider range of applications. They are mainly applied in fields such as HVAC and indoor air quality monitoring, industrial process and safety protection monitoring, and agricultural and livestock production process monitoring.

Environmental monitoring with gas sensors has become an urgent need for environmental protection

The increasingly urgent demand for environmental protection, coupled with the continuous development of sensor technology itself, is driving environmental monitoring to become one of the first highlight applications to be implemented in the vertical field of the Internet of Things (IoT). Gas sensors, water environment detection sensors, soil pollution detection sensors, etc. have become the "three cornerstones" for establishing environmental monitoring systems and are receiving increasing attention from all sectors of society and the state.
