With the improvement of living standards, the whole society's awareness of environmental protection, people are more and more concerned about the health of the living environment, more and more concerned about the air quality of life, and more and more demanding for the provision of environmental information. Whether the air quality has begun to deteriorate, which places are deteriorating, the degree of deterioration, how the development trend, experts are concerned about it, the people are concerned about it, and more concerned about it. The public release of air quality conditions through media communication is not only conducive to the openness and transparency of environmental protection work, but also helps to promote public awareness of environmental protection and participation in environmental protection work.

Most areas still use manual sampling and laboratory analysis as the main means of atmospheric monitoring, which cannot timely and accurately monitor the real-time emission of pollutants, making it difficult for environmental management personnel to map out the actual situation of all polluted areas in a short period of time, as well as to monitor and deal with all kinds of sudden sources of pollution and polluted sites in an immediate and accurate manner. With the use of air quality monitoring system, can be very good to help people understand the situation within the atmospheric environment, to help the relevant departments to carry out monitoring and management of atmospheric monitoring.

The significance and purpose of air quality monitoring is mainly reflected in the following aspects:

1. Understanding the Dynamic Changes of Air Pollution: Air pollution is a complex and dynamic process that is affected by a variety of factors. Conducting air quality surveys can monitor changes in air quality in real time and understand the sources and composition of air pollution, so as to better understand and respond to air pollution problems.

2. Early Warning and Prevention of Air Pollution: Through air quality monitoring, we can detect and warn of air pollution in a timely manner and remind people to take appropriate protective measures. At the same time, it also provides a scientific basis for pollution prevention and control, so that more targeted measures can be taken to reduce the impact of air pollution on human health and the environment.

3. Raising Public Awareness of Environmental Protection: The results of air quality monitoring can make the public more aware of the problem of air pollution and raise the level of importance attached to environmental protection. Through the real-time release of data, it can make more people pay attention to and participate in environmental protection actions, and jointly contribute to the improvement of environmental quality.

4. Providing Bases for Policy Formulation: Data from air quality monitoring can be used not only for the formulation of environmental protection policies, but also for assessing the effects of policy implementation. By comparing and analyzing data from different time periods and different regions, the effect of policy implementation can be understood, providing a basis for policy adjustment and optimization.

5. Promoting the Construction of Green Buildings and Healthy Places: The goals of green, healthy and sustainable development can be better achieved by taking air quality issues into account in building design and place planning. For example, the introduction of a real-time air quality monitoring system can provide a better understanding of the indoor air quality situation, so that appropriate measures can be taken to improve the indoor environment.

Overall, air quality monitoring is of great significance and purpose for us to understand and tackle air pollution problems, to raise environmental awareness and to promote sustainable development.
