Design and manufacture of air quality measurements based on arduino ATmega 2560 using dust ZH03A laser sensor

This study aims to design an air quality measuring instrument that is more efficient, relatively cheaper and can be carried because it has a smaller shape and size compared to the existing tools in the Meteorology, Climatology and Geophysics Agency (BMKG). The main processor uses the Arduino ATmega 2560 microcontroller. This microcontroller functions as a processor for PM2.5 and PM10 concentrations which are the output of the ZH03A sensor. The design results are calibrated with a standard tool, namely BAM1020 which is owned by the BMKG air quality sector to measure air quality. The calibration results obtained that the average value issued by the reference tool which is used as a standard compared to the ZH03A sensor in the design results for PM 2.5 is 6.5 µm / m3, and for the average value of PM1.0 is 2.8 µm / m3 the calculated Air Pollution Standard Index (ISPU) value is 126 µm / m3 including the medium category according to the Air Pollution Standard Index.
