Abstract
Cities around the globe are facing ever-increasing challenges to air quality, posing serious risks to public health due to high levels of particulate matter and various pollutants. Addressing these challenges requires a multifaceted strategy, including strict regulations, sustainable urban planning, and adopting cleaner technologies. To tackle these issues, we developed a portable personal air monitor designed to effectively assess environmental conditions. This innovative device incorporates a range of sensors and a filtration system to measure concentrations of different pollutants. What sets it apart is its unique design inspired by the human lung, utilizing a diaphragm vacuum pump to mimic the natural breathing rate. The filtration system employs filter paper capable of capturing microorganisms, which can then be cultured and analysed. This feature provides valuable insights into the microbial makeup of the air, enhancing our understanding of environmental health dynamics. Integrated sensors cover a wide spectrum, detecting particulate matter such as PM2.5, PM10, and PM1.0, as well as gases like CO, CO2, NO2, TVOC, and parameters such as humidity and temperature. This comprehensive array of sensors enables a thorough assessment of environmental pollutants and their associated health impacts. A user-friendly interface, facilitated by a Bluetooth module, offers real-time feedback on air quality parameters by receiving data from the Arduino processing unit. Additionally, an SD card module stores data for later analysis and reference across various locations. This device is powered by a battery, making it portable and convenient for use in diverse settings.
