Tragbares System zur Messung der Aussenluftqualität mit Arduino

The recent occurrence of haze in Malaysia has prompted the public to become more aware of the current air quality in their surroundings. Air pollution can have serious effects on human health and the environment. The Air Pollutant Index (API) in Malaysia is measured by the Ministry of the Environment using stationary and expensive monitoring stations, known as Continuous Air Quality Monitoring Stations (CAQMs), which are only set up in areas with high population density and significant industrial activities. Furthermore, Malaysia has not included particulate matter smaller than 2.5 µm (PM2.5) in the API measurement system. In this book, we present a cost-effective and portable air quality measurement system equipped with an Arduino Uno microcontroller and four inexpensive sensors. It is capable of measuring the concentration of carbon monoxide (CO), ground-level ozone (O3), and particulate matter (PM10 & PM2.5) in the air and converting the measurements into API values. The measured API value was compared with the current API value recorded by the Department of Environment (DOE) at several locations. The results of the experiment demonstrate that this air quality measurement system is reliable and efficient.
