Harmful atmospheric pollutants have been attributed to causing adverse weather conditions and health problems, which are particularly prevalent in more populated global regions, such as megacities. Nongovernmental and international agencies throughout the world have likewise called for increased awareness and action to effectively counter the increased rates of air pollution, as the consequences seem ominous. Meanwhile, in several major urban landscapes such as Saudi Arabia, no modern apparatus or efficient systematic mechanisms exist for the qualitative detection of dangerous pollutants and gases. The current counterparts for hazardous gas measurements are expensive, bulky and cumbersome to set up. Thus, sensor devices that are portable and quicker at obtaining ambient air measurements are desirable to fill the current gap in effective air pollution monitoring. Our objective in this research was to better understand and explore relatively cost-effective, flexible and dynamic sensors in real-time monitoring that can function efficiently in modern day environments and regions. The suitability of these new age sensors were analyzed for gases such as nitrogen dioxide (NO2), sulfur dioxide (SO2), carbon monoxide (CO), particle pollution (PM2.5, PM10), and ozone (O3). The study area was Riyadh, Saudi Arabia.
