Air pollution monitoring in IoT

With the rapid development of the Internet of Things (IoT) technology, people's lives have become more intelligent, and the application of IoT in the field of environmental monitoring is particularly important. Air quality is one of the most important environmental indicators in people's lives, so the application of IOT in air quality monitoring and early warning has attracted much attention.

Air quality monitoring technology under the environment of the Internet of Things

The air quality monitoring technology under the environment of the Internet of Things mainly includes sensor technology, data transmission technology, and big data analysis technology.

1. Sensor Technology

Sensors are the key components for air quality monitoring in the IoT environment. Through sensors, the concentration information of various air pollutants, such as PM2.5, carbon dioxide, ozone, etc., can be obtained in real-time. With the continuous development of sensor technology, the size of the sensor is getting smaller and smaller, and the accuracy is getting higher and higher. At the same time, the sensors can automatically collect data and transmit the data to the cloud platform for real-time analysis.

2. Data transmission technology

In the IoT environment, the transmission of air quality monitoring data needs to rely on wireless communication technologies, such as cellular networks, Wi-Fi, Bluetooth, and so on. These technologies can transmit the data collected by the sensors to the cloud platform or cell phone terminals. At the same time, the Internet of Things can also use wireless sensor network technology to build a wide coverage air quality monitoring network and realize data sharing between multiple sensors.

3. Big data analysis technology

Under the environment of the Internet of Things, a large amount of air quality data obtained needs to be effectively analyzed and processed. With the help of big data analysis technology, valuable information, such as spatial and temporal distribution and change trends of air quality, can be mined from the massive data. This information is important for formulating effective environmental protection policies and responding to environmental emergencies.

Air Quality Monitoring and Early Warning System under the Internet of Things Environment

The air quality monitoring and early warning system under the environment of the Internet of Things can realize real-time monitoring, early warning, and traceability functions, provide people with accurate air quality information, and help them make scientific decisions.

1. Real-time monitoring

Sensors can collect air quality data in real-time and transmit them to the cloud platform through wireless communication technology. On the cloud platform, air quality monitoring data can be displayed and monitored in real time and can be tracked and managed at any time.

2. Early warning function

Based on big data analysis technology, the air quality monitoring and early warning system can predict future air quality trends based on historical and real-time data, and issue early warning information in advance. When the air quality indicators exceed the predetermined threshold, the system will automatically issue an alert to remind people to take appropriate protective measures.
