Many people interested in indoor air quality monitoring since they spend a majority of their time indoors such as homes and offices. This paper proposes the effective indoor air quality monitoring system and it can gauge carbon dioxide, particulate matter and VOCs(Volatile Organic Compounds) which can be harmful to humans. The proposed system is composed of three main modules which are device, web server, and mobile application. In order to evaluate the performance, we tested two cases which are candle and smoke. We monitor the condition of indoor air quality with our mobile application. Also, we developed the information graphics to compare the condition of air quality between indoor and outdoor and this mobile application improves usability.
