도시철도 터널에서의 미세먼지 특성 파악 및 측정 장치 개발

Characteristic and Development of Measurement Device for Particulate Matters on the Subway Tunnels

Objective of this study was to characterize $PM_{10}$ sources on subway tunnels and development of simple particulate matters measuring device based on wireless sensor network. A new wireless sensor module, PMX, has been designed and manufactured to measure $PM_{10}$ and$PM_{2.5}$ simultaneously. The measurements have been conducted at a specific subway station on the Seoul metro line. The accuracy of the device was verified and compared with commercial measuring device based on weighting method.
