Background:

There are many kinds of sensors, which are widely used in daily life in recent years. For example, in artificial intelligence, smart city and other builders are playing an irreplaceable role. Gas sensor is an important branch of sensor family. Commonly understood, the gas sensor is to collect information such as gas composition and concentration in the air. Analysis is converted into data that can be directly used by researchers, instruments, computers, etc.

Through the continuous development of sensor technology, more and more gas sensors appear, semi-conductive gas sensors, solid electrolyte gas sensors, contact combustion gas sensors, electrochemical gas sensors, optical gas sensors and so on have sprung up in the market. Nowadays, a wide variety of gas sensors are widely used in industry and environmental monitoring.

Application of gas sensor in industry：

In industry, gas sensors are mainly used in the petrochemical industry to detect carbon dioxide, nitrogen oxides, sulfur oxides, ammonia, hydrogen sulfide and chlorine and other harmful gases. The semiconductor and microelectronics industries detect highly toxic gases such as organic solvents and phosphoane. The power industry detects the hydrogen produced in the metamorphic process of power transformer oil.

Application of gas sensor in industrial environment monitoring：

In environmental monitoring, gas sensors are mainly used to monitor air quality. Sensors are used to detect air quality, temperature and humidity, nitrogen oxides, sulfur oxides, hydrogen chloride and other gases that cause acid rain. Detection of carbon dioxide, methane, nitrous oxide, ozone, freon and other greenhouse gases. Detection of ozone - depleting gases such as ozone and freon; Detection of ammonia, hydrogen sulfide and gas unpleasant gas, etc. In the construction of environmental Internet of things, gas sensor is playing a vanguard role. In recent years, the environment on which human beings live has been severely damaged. Effective protection of the environment requires the establishment of environmental monitoring system. In this case, building an environmental Internet of things becomes necessary. As a necessary sensor for environmental detection, gas sensor will contribute to the construction of environmental Internet of things.

The role of gas sensors in life：

In life, gas sensors can also monitor indoor air quality. It can be used in air conditioning, fresh air system, smart home, air purifier and so on. In addition, it can also be used in the kitchen to detect gas leaks, such as natural gas, or in appliances such as microwave ovens. Automatic control of microwave cooking food by detecting the gas generated during cooking.

Air Quality Monitoring System：

Air quality monitoring station, grid air environment monitoring system, micro air monitoring station are used to provide products for real-time and accurate monitoring of outdoor air pollutants. The air quality monitoring station adopts an integrated sensor, which is light and small, beautiful in appearance, and easy to install. It can be calibrated according to the site, and customers can choose corresponding products according to specific needs or environments. The air quality monitoring system is used to provide products for real-time and accurate monitoring of outdoor air pollutants. The air quality monitoring system integrates "Four Gas and Two Dust" (SO2, NO2, CO, O3, PM2.5, PM10) sensors combined with wireless communication technology to achieve real-time data monitoring, and collect environmental big data on the "cloud platform" to provide a network The grid platform provides a data foundation.

Future development of gas monitoring equipment

With the continuous improvement of people's living standards and the increasing attention to environmental protection, the monitoring of air pollution, industrial waste gas and the quality of food and living environment have put forward higher requirements for gas sensors. In the future, gas sensors should focus on the research and development of new gas sensitive materials and production processes, and develop new materials with high sensitivity, high selectivity and high stability. Nowadays, the successful application of nano, thin film technology and other new material development technologies provides a good prerequisite for the integration and intelligence of gas sensors, and the development of intelligent automatic gas sensors that can detect a variety of gases is also a major development direction in the future.

Gas sensor is a bridge between artificial intelligence and information. High-performance gas sensor can greatly improve the level of information collection, processing and deep processing. Through real-time monitoring, the hidden dangers in the environment, industrial production and life can be found in time to achieve effective safety supervision and prevent them from happening. At present, gas sensors occupy a large proportion of the market share, with the innovation of technology, the advent of new products, gas sensors will open up more markets, in all kinds of fields we will see more gas sensors.
