The problem of urban pollution has received widespread attention from people now, and scientists have been working hard to solve the problem of urban air pollution for many years, allowing people to breathe fresh air. However, it seems that air pollution is becoming increasingly serious so far.

1Grid based air quality detectoroverview

The YT-AQI grid based air quality monitoring micro station is a new type of online multi parameter monitoring system for air quality produced by Yuntang Keqi Company based on the 13th Five Year Plan and local air pollution monitoring and control policies. It strictly monitors 13 parameters including four gases (CO, SO2, NO2, O3), two dust (PM2.5, PM10), meteorological five parameters (temperature, humidity, wind speed, wind direction, air pressure), and optional TVOC in accordance with national standards, and visualizes the data through a big data analysis platform to achieve remote monitoring, remote warning, and strict prevention and control of pollution sources.
