As a continuation of the environment-sensing IoT (Internet of Things)-related projects during 2017-2019, the project has assisted the Environmental Protection Administration in building a micro sensor-based smart environment management system. As of the end of Oct. 2020, much work had been completed, including evaluation of the development of IoTs, both in Taiwan and abroad, collection of related domestic and foreign literature and information on foreign practices, as reference for deployment plans in the future, and tracking of domestic sensor deployment, including sensor brands; completion of survey-station comparisons for indigenous PM2.5, NO2, and O3 sensing modules, calibration of the correlation between sensing components and survey stations with ANN (artificial neural network) algorithm, with post-calibration data R2 topping 0.6; sensing data calibration and testing, data fusion, and attenuation analysis in expanding interpretation and application of environment sensing data, showing absence of obvious attenuation for most sensors and significant identification ability of mobile sensors for high polluting vehicles and road-side high polluting sources, conducive to the construction of basic regional-environment data; deployment and operation/maintenance of 10,200 sensors nationwide, in collaboration with municipal governments; continuing promotion of exchanges between private and public sectors, including discussion for deployment strategy and improvement measures, assistance for municipal governments in checking the operation and maintenance of sensors and data quality, plus tailor-made planning and implementation; setup of dedicated office which has compiled its own SOP (standard operation procedures) and Q＆A and established 2021-2025 target for air-quality IoT; completion of the preliminary report on the 2017-2020 implementation results and analysis of the international air-sensing development trend. Therefore, since its onset in Feb. 2020, implementation rate of the project has reached 100%, meeting the condition for the compilation of a final report. In sum, completed works include analysis of the international IoT development trend, improvement of indigenous sensor technology, expanded interpretation and application of environmental sensing data, integrated verification of the execution result of environment sensing IoT, assistance for municipal governments in the establishment of sensing IoT, setup of dedicated office for pushing sensor industry and application, improving sensing data quality and application efficacy, coordination of the efforts of industry, government, and academic in the development of IoT technology, and materialization of smart city and environment-related law enforcement. With Taiwan as the verification field, the project has contributed to environment-related smart law enforcement and made local people aware of the function of environment sensing IoT in environmental governance.
