  Abstract

The fine particulate matters are associated with an increased risk of respiratory and cardiovascular deceases. The mass concentration of the fine particulate matter (PM2.5) can dramatically change, so it is necessary to continuously measure the PM2.5 mass concentration. In addition, aerosols can grow up by absorbing water in a high relative humidity. This hygroscopic growth can make an error to monitor the PM2.5 mass concentration. To lower relative humidity, the most of PM monitors include an indirect heating device, which is big and consumes a large electrical energy. This paper proposes the system architecture of the continuous PM monitor and the implementation method of a small direct heating device (is called Tiny Aerosol Conditioner), which is small, has a high energy-efficiency, can be made as a portable device. This continuous PM monitor periodically transmits measured data to a server through wireless LAN. The data can be protected from cloning attack and tempering by time-token constraint scheme and hashing. During 30 days with great changes of relative humidity, the proposed device was compared with the measured results of National Institute of Environmental Research of South Korea and was proven to be of high accuracy.
