Abstract
This paper proposes a simple sensor system development for supporting elderly people, and the constructible method of a senior-friendly community using it, and verifies these significance and reactions of people involved in this pilot program. We have developed the sensor system with excellent cost performance by using a low cost sensor and sharing the internet line and access fee among the elderly single population. These sensors unit are able to interact with weak radio wave. If the behavior of the elderly is not detected over a setup time, each sensor unit which is installed at the entrance of each room flashes LED of all sensor units to communicate with each other. These illuminations is converted to noticeable light, send a strongly information of the abnormal elderly state to neighbors and passers. At the same time, this system will notify by e-mail in real-time to support staff and officials. Major role of this system behave as a trigger to widely contact a network of community members.
