The main work items actually completed in this project and the summary of the results are as follows: 　1.Complete the deployment detailed planning and data application analysis method report. 　2.Complete the deployment of 500 sensor stations. 　3.Data analysis for the sensor after deployment, including: 　　A. The real-time border sensor data of the border counties and cities obtained from the EPA IoT platform are incorporated into the team's analysis platform for integrated analysis. 　　B. Interface with the fire information on the EMIC platform of the Fire Department, and provide automatic positioning and trend graph presentation of the affected sensors in the analysis platform of the team. 　　C. Assist in the sensor data analysis of temporary events in the agency, including fireworks and temple fairs, and auxiliary analysis of the sentiment of the industrial zone built in 2018 to 2019. 　　D. The line warning information also prompts the location and information of the controlled pollution sources around the incident site for inspection. The personnel can refer to it in real time, and can filter the more suspicious controlled pollution sources on the map according to the filtering conditions during the post-analysis. 　　E. Discussion on the setting of warning thresholds for odor sensing. 4.Plan the following year (2021) to continue the practice of air quality sensing the actual benefits of the Internet of Things built in this plan.
