Design and analysis of air quality monitoring system PM₁₀ and PM_2.5 integrated with weather parameters (a case study on Margonda Raya street Depok)

An observation of air quality is very important related to the increasing pollution in Indonesia resulted from the use of motor vehicles, industrial activities, wildfires, and others. It triggers the increase of PM₁₀ and PM_2.5 particulate pollutants in the atmosphere. Meteorological factors influence the fluctuation of PM₁₀ and PM_2.5 concentration. The solution to overcome the problem is the design of IoT-based PM₁₀ and PM_2.5 digital monitoring system that is integrated with parameters of temperature, humidity, wind speed and direction. The design system consists of sensor hardware ZH03A laser dust sensor, SHT11 temperature and humidity sensor, and JL-FS2 wind speed and direction. Data were processed on Arduino ATMega2560-based microcontroller and then sent to the server using internet so that they could be displayed on website. The information system on the website was developed using PHP and HTML. The device had been tested with calibration and comparison methods. As the results of the research, the device could be operated properly and the measuring results were displayed on web in real time to provide air quality information. The correlation of PM source concentrations with meteorological parameters is that temperature (positive correlation), wind speed (positive correlation), relative humidity (negative correlation) and based on the direction of wind, the area is dominated by west winds.
