With the vigorous development of Internet technology, the application of Internet of Things technology is spreading across all major fields. This project combines air pollution sensors with Internet of Things applications to create air pollution monitoring and immediate response effects, creating smart monitoring and technology law enforcement to control air pollution Purpose. Taichung City has set up 350 air quality micro-sensors to measure items mainly including PM2.5, temperature and humidity, etc. (TVOC is also added). At the same time, 20 sets of wind speed and direction meters are set up around the industrial zone and 10 sets of green energy equipment are set up. On some sensors. In order to ensure the quality of the sensed data, through quarterly inspections and parallel attachment comparisons, the sensors with obviously poor data quality are simply overhauled or replaced on-site to maintain data quality standards. Since the sensor was officially launched on January 7, 109, the complete rate of uploaded data has reached more than 90%, achieving the purpose of effective data upload. In order to enable the general public, government agencies, enterprises, and non-governmental organizations to become more familiar with the air quality sensor activities promoted by the government, the two air quality sensor awareness announcements have been completed on August 14 and 27, 109. The guide will also use the sensor to promote the production of the video, and inform the public about the real-time query function of Taichung's exclusive sensor mobile webpage and the air pollution warning hazard, so that the public can be more familiar with the exclusive web query method, so that the public can know the status of empty products And health protection methods. According to statistics, as of December 31, 109, the review report, the mid-term report review, the sensor migration operation, and the monthly inspection of the sensor clusters and the first and second quarter inspections during the execution period have been completed within 90 days from the performance of the contract. Monthly work report (completed from May 109 to December 109), completion of 2 air quality awareness promotion sessions, 3 promotional scripts and videos, valid data of monthly sensing data and data quality integrity rate of 90 % Or more (98.44% in May, 98.93% in June, 97.72% in July, 95.64% in August, 98.49% in September, 95.42% in October, 97.17% in November, 95.20% in December) and monthly data creation and analysis Data application and dedicated air quality micro-sensor webpage maintenance, the cumulative total progress is 100% completed.
