Development of local area alert system against particulate matters and ultraviolet rays based on open IoT platform with P2P

Special attention needs to be paid to particulate matters and ultraviolet rays since they may cause diseases such as respiratory ailment and skin troubles when the exposure level is excessive. To reduce damages by environmental elements in Korea, the Korean Meteorological Agency provides environmental information real-time. However currently environmental information services are based on the administrative districts, there is a limitation in providing information on particulate matters and ultraviolet rays in the neighborhood efficiently. Besides, particulate matters or UV dosimeters that were released recently are operated individually and thus it is difficult to measure various environmental elements simultaneously. This study proposes a neighborhood particulate matters and ultraviolet rays warning system that utilizes a P2P-based open IoT platform in order to provide users with information on harmful environmental elements efficiently. The proposed system establishes an open IoT platform that manages collectively IoT smart devices capable of measuring particulate matters and ultraviolet rays, the measured data, and RSS data provided by administrative institutes. In addition, this system provides alerts based on the level of particulate matters and ultraviolet rays in utilization of a smart-phone application that provides environmental information, contributing to maintaining users’ healthy life patterns.
