School air quality monitoring station

The school air quality monitoring station, as the name suggests, is an air quality monitoring station installed in the school, which monitors the concentration and change rules of pollutants in the campus air and issues early warning information to teachers and students in time, so that teachers and students can take timely measures to deal with it.

School air quality monitoring station FT-WZ02 according to the standard construction, according to the national standard for four gases (CO, SO2, NO2, O3), two dust (PM2.5, PM10), meteorological five ginseng (temperature, humidity, wind speed, wind direction, air pressure), optional TVOC, multiple parameters monitoring, And the data is visually displayed through the big data analysis platform to achieve the goal of remote monitoring, remote warning, and strict prevention and control of pollution sources.

The system is designed and developed based on Internet of Things technology. It is composed of sensor nodes, data transmission module and monitoring center. It adopts modular structure and can easily expand functions. The sensor nodes include temperature sensor, humidity sensor, dust sensor and pollutant sensor, etc. The data transmission module includes GPRS, 4G transmission and other network transmission devices; The monitoring center includes two parts, the server and the client, which are responsible for data collection, analysis and calculation, display alarm and storage of historical data.

With the development of social economy and the improvement of scientific and technological level, people's lifestyle has undergone great changes, and higher requirements have been put forward for education. Therefore, schools must pay attention to air quality monitoring. At present, many areas in China have established school air quality monitoring stations with primary and secondary schools as the main places. Through the practice of these years, it is found that the school air quality monitoring data is not only related to the health of teachers and students, but also affects the protection of the local environment, so it is of great significance to strengthen the construction of school air quality monitoring stations.
