Abstract: The present invention relates to a disaster safety system using a combined beacon and a method for processing thereof. Various low-power sensors are combined with the combined beacon, which measures various environmental information for an installation place through a wireless communication network. The combined beacon supports, for example, Bluetooth and Bluetooth smart standards. The combined beacon combines sensors required by a user to measure and collect the environmental information for the installation place. The disaster safety system is provided to measure and collect various environmental information for the installation place in real time by using a combined beacon in which a plurality of sensors is combined and provide the environmental information to a smart device of a user and collect, analyze, and monitor the environmental information and predict and determine whether a disaster occurs at the installation place.
