碩士 === 國立臺東大學 === 進修部教育行政碩士班(夜間) === 104 === In this study, we have utilized four groups of low-cost, simple, and convenient devices for monitoring the concentration of PM2.5. These devices use Arduino compatible board LinkIt ONE binding dust sensors, with Wi-Fi wireless transmission. The PM2.5 monitoring data in different classrooms is uploaded to the cloud server MCS. According to the school’s daily schedule, and with regard to aggregated data and analysis, the findings are concluded as: 1) Indoor PM2.5 density increased significantly because of the activities of students in the classroom, especially during cleaning activities; 2) During cleaning activities, PM2.5 density in basement classrooms increased much more than that in second floor classrooms; 3) Compared to when students enter the classrooms with shoes, PM2.5 density is significantly lower when the shoes are taken off in the same classroom; 4) PM2.5 density in wood-floor classrooms is obviously lower than that in terrazzo-floor classrooms.
