Air Quality Monitoring: Engineering Smart Sensors
Ariowachukwu Divine Sopruchi
ABSTRACT
Air quality monitoring plays a crucial role in safeguarding public health and environmental sustainability. The increasing levels of air pollution due to industrialization and urbanization have necessitated the development of advanced monitoring technologies. Smart sensors, equipped with Internet of Things (IoT) capabilities, offer real-time, cost-effective, and scalable solutions for detecting airborne pollutants. This paper examines the principles of sensor technology, including electrochemical and optical sensors, their integration with IoT, and the development of smart air monitoring systems. Applications of these sensors in urban, industrial, and remote settings are examined, highlighting their role in data-driven decision-making for air quality management. Challenges such as sensor calibration, standardization, and data security are also discussed. Finally, emerging trends, including artificial intelligence (AI) integration for predictive analysis, are reviewed, emphasizing the future of air quality monitoring systems in achieving sustainable environmental health.
Keywords: Air quality monitoring, smart sensors, Internet of Things (IoT), electrochemical sensors, pollution detection, environmental sustainability.
