The project has finished the goals as planned. Regarding the volunteer program, the project has finished the following works. (1) We proposed a basic goal for our volunteering activity, that is, ‘enhance people’s awareness about the PM2.5 emission and establish citizenship behavior regarding air pollution’. (2) We have held many promotion activities about air pollution control in the five townships to encourage people to be the frontier of air pollution control. (3) In order to reduce the air pollution in the traditional market, we have cooperated with the volunteer to develop a bike and a shopping cart equipped with the PM2.5 sensor. Regarding the maintenance of the IoT system, the following works have been completed: (1) All of the existing monitoring points have been maintained and their PM2.5 sensors have been upgraded to the newest version. (2) We have maintained the whole system and handled any emergency of the system 7/24. (3) We have provided real-time data every 10 minutes online. (4) A sectional calibration method for PM2.5 sensor has been applied to get calibration parameters for each section based on the sensor data of the past year.
