Abstract: As atmospheric air quality is worsening day by day as climate changes, indoor air quality
is also influenced by daily activities as well. Nowadays, particulate matters from various domestic
sources are emitted, transformed by sunlight and transported into Korea from overseas. Due to these
reasons, there have been high demands to monitor and improve air quality as functions of contaminant
concentration and type that enables us to track its source and transport. In this study, spectral sensor
to reveal wavelength and chromameter to show chromaticity values of reflected light of specific
particles were utilized. Five different type of particulate matters were observed to elucidate the
relationship between property of particulate matter and detected light spectrum and optimum
approach to assist current sensor was suggested.
