With the development of industrial civilization and cities, while creating huge wealth for mankind, energy consumption is also continuing to increase, and the pressure to prevent and control air pollution continues to increase. There are various sources of air pollution. Industry, catering industry, and construction industry can all pollute the atmosphere. Good ambient air is one of the important indicators of people’s quality of life. With the debate surrounding climate change, air pollution is increasingly becoming a major concern in many cities around the world.
In recent years, Internet of Things (IoT) technology has developed rapidly, linking various sensors with objects used in daily life, exchanging information through the network, and providing various service needs, such as smart transportation, smart homes, disaster monitoring, etc. It makes life more and more convenient and gradually changes our lifestyle. Currently, IoT technology is also widely used to improve ambient air quality.
Today, smart cities based on the concept of sustainable development are actively fighting air pollution. Many cities are moving towards smarter infrastructure or solutions such as traffic monitoring to help solve this problem. They are implementing green legislation to create greener spaces. For example, Paris is expanding its car-free zone and Tokyo is further investing in renewable energy to become more sustainable and resilient, and has already achieved tangible results. income.
While heavily polluted cities like Delhi and Beijing are using smart sensors to alert residents when air pollution levels are high, this is not a fundamental solution to the problem. IoT is providing better pollution data than ever before, which can be used to drive actionable initiatives. For example, in the Swedish city of Uppsala, a Green IoT project is monitoring air pollution in real time through wireless sensors on buses. Create integrated solutions for environmental sensing systems. With this sensor data, government agencies can use the data to control traffic to make informed city planning decisions, such as steering vehicles around high-pollution areas.
Reducing pollution is critical to the future of smart cities and doesn’t require much technology. The European Environment Agency (EEA) reports that electric vehicles have a positive impact on air pollution compared with equivalent petrol or diesel cars, and many cities are already setting an example by promoting increased use of electric vehicles.
On the other hand, the industrial environment monitoring system is used to establish a grid monitoring system based on pollutants to collect real-time statistics on monitoring equipment data in each factory area and monitoring point. It is combined with advanced technologies such as the Internet of Things, intelligent collection systems, geographic information systems, and dynamic icon systems. technology to monitor harmful gases such as nitrogen oxides, four gases and two dusts in industrial production, control unorganized emissions from pollution sources, reduce industrial pollution, and provide reliable data information and scientific auxiliary management decisions for customized energy-saving and emission reduction plans.
Through IoT sensors, governments have the ability to help reduce pollution by changing traffic routes and urban planning. Additionally, advances in technology are making low-power wide area network (LPWAN) sensors a low-cost alternative to fixed monitoring systems, making them an increasingly attractive option. Many cities have already taken the first steps to integrate IoT solutions into their ecosystems and are realizing long-term benefits as a result. Ultimately, understanding the sources, causes, and trends of pollution will allow cities to control air pollution and effectively curb climate change, and that’s where IoT comes in!
