Abstract
Thailand now faces many environmental problems, particularly air pollution and particle pollution in many cities. These cities are economic cities and have industrial zones, congestion of people, and heavy traffic. Previous studies showed that levels of Carbon Monoxide (CO) or Nitrogen Dioxide (NO2) exceeded the standards at 30 ppm./hr. or 0.17 ppm./hr., respectively, in industrial zones, or congestion areas. People, who are living in these areas, are facing severe air pollution crisis. Moreover, people rely on the air quality reports but in fact air pollutants are still affecting the people health. People are not aware of the risks and do not keep themselves safe. The average air quality was reported by the Pollution Control Department in a particular area. Based on our survey results, we found that the air quality or the levels of pollution in certain areas is different from the AQI value reported by the department. People suggested that they did not regularly access a web site to see the air quality report. They did not know exactly what pollutants are in the air. They need to see real-time air quality information and request to see proactive air quality information to make people aware of pollution. We proposed the development of portable air quality monitor devices to solve problems. The devices are small. They can provide high-accuracy measurements and can be equipped with the vehicle or mobile unit. They can be used to measure air pollution levels in in certain areas and provide a real-time report. The data from each device is sent to cloud through a wireless network. Government or non-government agencies can make data-driven analysis and decisions, gain more benefits of sharing data, and utilize them with existing data. In this research, standard equipment was designed and developed. The Front-End and Back-End systems were developed to properly manage and store data, link to data sources and visualize data efficiently. The proposed solution in this research differs from prior research. This research serves the following purposes: (1) enhancing climate technology development and transfer, (2) developing open data platform for environmental sustainable development, and (3) serving the country's public health.
