Feasibility of an IoT based Operational Air Quality Monitoring System for Sri Lanka

Lower-cost air quality sensors, Internet of Things (IoT) technology, advancements in air quality and wind modeling, and tools for rapid information dissemination via Internet portals, social media, and smartphones provide an opportunity for such work. An operational system for air quality monitoring in Western Sri Lanka has been developed, aiming to provide authoritative information on air quality, its sources, impacts, and mitigation options in Sri Lanka. The system's objectives include providing detailed current and recent air quality information, serving as a resource for training, research, and research in air quality, facilitating communication of air quality information specific to affected audiences, and supporting advocacy and policy decisions to promote clean air in Sri Lanka. Real-time and historical data are obtained remotely using 24 low-cost pm2.5 sensors, which are connected online to display the current air quality status at selected locations. The monitoring devices are subject to fault-rectification, and data from all instruments are displayed on a website. The website provides information on air quality, compiling publicly available data, using modeling approaches combining wind and weather stations, and employing advanced IT tools for data processing, visualization, and visualization using IoT technology. The website is available in Sinhala and Tamil, along with an introductory section. This effort has provided a proof-of-concept in four of nine provinces of the use of an IoT-based operational air quality monitoring system, which provides usable information. The system was recognized by the Information and Communication Technological Agency of Sri Lanka in 2020 with a competitive award. The system's website, www.clean.lk, is a resource for air quality information, providing real-time and historical data, as well as information on air quality, its sources, impacts, and mitigation options in Sri Lanka. The website is accessible through various platforms, including Internet portals, social media, and smartphones. The system's objectives include providing authoritative information on air quality, its sources, impacts, and mitigation options in Sri Lanka, as well as serving as a resource for training, research, and research in air quality.
