With the development of the economy and the improvement of material living standards, cars have begun to enter households in large numbers in China, and underground garages have become a necessary supporting facility for real estate construction projects. At the same time, automobile exhaust has become the main source of air pollution in large cities, and underground parking garages have also become one of the main sources of air pollution in real estate projects. Due to the fact that underground parking garages are places where urban people enter and exit daily, mechanical air supply and exhaust systems are equipped in the design to ensure air quality inside the garages. However, their operating conditions are not satisfactory. Multiple studies and experiments have shown that underground parking garagesCO、NOXreachPM2.5Dust and other pollutants significantly exceed the standard and have a negative impact on human health activities. Implementing effective and targeted environmental monitoring plans for underground parking garages in public places such as residential areas plays an important role in improving urban air quality, enhancing the quality of life in residential areas, and developing smart environment construction for urbanization.

Osen underground garage grid based micro air monitoring station focuses on underground garage pollution sources: carbon monoxide, nitrogen compoundsPM2.5、PM10Monitor indicators such as meteorological five elements, and establish unmanned real-time monitoring automatic monitoring stations to obtain continuous online air quality monitoring data in a timely manner.

System functional features:

1、Equipped with cloud based automatic online calibration function, it automatically corrects sensor drift and environmental interference without the need for on-site manual calibration.

2、Adopting a louver stack design, suitable for various weather conditions, ensuring no dead corners in air circulation and no temperature difference between inside and outside.

3、Can simultaneously monitor gas parameters and inhalable particulate matter, and display monitoring values on the data platform;

4、Tool free disassembly, convenient for point migration and equipment maintenance.

5、Adopting imported high-sensitivity sensors, with fast response time, high resolution, good linearity, and detection offline capabilityppbGrade;

6、The combination of microcontroller technology and network communication technology, using data storage function, not only provides convenient data query methods; It can also be done throughUSBThe interface transfers the data to the computer, and uses the supporting upper computer software to automatically calculate the daily average, monthly average, pollution index, generate various graphical data labels, and print them;

7、Adopting internal lithium battery power supply and external solar power supply to solve problems such as wiring and power connection

8、Stable performance, high accuracy, easy operation, easy maintenance, and power-off protection function;
