Abstract
Commercial air quality monitoring systems can measure PM10 very precisely and accurately but are expensive to procure and maintain. The research objective was to design a portable, easy-to-handle, real-time PM10 monitor using a particle counter PPD42NS, cyclone separator, vacuum pump, temperature, relative humidity, and air pressure sensors types BMP085 and DHT22. A comparative study of meteorological factors between Vantage Pro 2 and the BMP085 and DHT22 sensors shows a positive linear correlation. The sensor was used to correct the air sample flow rate in the PM10 concentration formulation. The air sample flow rate is stabilized at 0.7 L min−1 so that the cyclone separator can work optimally. The particle size analyzer (PSA) analysis results show that the cyclone separator can separate particles less than ten microns in size at locations with low, medium, and high PM10 conditions. PM10 obtained from the separation process was measured with a PPD42NS particle counter and was successfully converted into mass concentration using a mathematical formula on the microcontroller. The PM10 monitoring system was tested for 24 hours in the wood processing area with a concentration of PM10 278.5 μg cm−3, which was categorized as unhealthy.
