Abstract
At this time, most houses for persons with disabilities are not yet equipped with a disaster mitigation system. It may be difficult for persons with disabilities to be able to save themselves when a disaster occurs. Therefore, in this study, a system for disaster mitigation, especially fires in the residence of a child with cerebral palsy, has been successfully designed. The optimal placement of the wireless sensor network is decided based on a behavioral architectural analysis using the DepthMapX-0.7.0 software. Behavioral architecture assessment begins by observing patterns of daily activities and a simulation of human movement in the house to find out the most frequent activity places used by children with cerebral palsy. Based on the test results with DepthMapX-0.7.0, it can be concluded that the optimal location of the sensor node points is in the child's bedroom, kitchen, and TV room. The designed wireless sensor network consists of three sensor nodes and a gateway node. Data sampling is performed every 15 seconds. If a fire is identified, the buzzer will emit a warning signal. In addition, the child's family can monitor home conditions from the ThingSpeak.com website and Telegram.
