Abstract
Air quality monitoring has become essential for understanding the impact of pollutants on health and the environment.
This paper explores the implementation of Arduino-based sensors in air quality monitoring, providing an affordable and
effective solution for tracking pollutants such as PM2.5, NO2, and CO2. The system comprises interconnected components,
including sensors for particulate matter, temperature, humidity, and volatile organic compounds, supported by real-time data
visualization platforms like ThingSpeak. These sensors enable real-time data collection, analysis, and visualization, allowing
users to identify pollution sources and make informed decisions for pollution reduction. The integration of IoT platforms enhances
spatial resolution and accessibility of air quality data, offering valuable insights for personal, scientific, and regulatory
applications. The study highlights the advantages of using cost-effective, portable sensors for improving environmental monitoring
and supporting sustainable urban development.
