Inspection and analysis of particulate matter exposure in construction by using individual measuring instrument

Abstract

At present, air pollution is considered an important environmental problem in Thailand, which can be observed from PM 2.5 that have exceeded the standard. This is due to changing lifestyles, population growth and constructions throughout Bangkok area and perimeter, especially the building construction, building renovation and building extension. These constructions cause air pollution and noise that affects workers and people living in the construction area, and it leads to health concerns. The large instrument, which is installed at one point, has been used for measuring dust in the construction area. This study aims to propose
a real-time air pollution and noise monitoring system in building construction projects by using IoT (Internet of Things) technology and air quality sensors to be installed with workers. This will let us know the concentration of air pollution and noise that the operator receives per day, also the activities that cause air pollution and noise pollution exceeds the standard. Then, the instrument was evaluated for functionality and discrepancy of the air quality sensor by comparing it with other standard instruments. The experiment in a small scale shows that the system can provide real-time values quickly and accuracy, also it is convenient to install and measure air pollution and noise pollution
