Design and Implementation of an Accidental Fall Detection System for Elderly

With the dramatically increasing of world population, the caring of elderly person becomes a globally concerned problem. The old want an independent living space and their family members need to work, so an intelligent old person surveillance system is in urgent need. An accidental fall detection system for elderly is constructed to detect whether an old person has fallen down and inform his or her family members through public mobile service, so as to get the elderly helped in time. This fall detection system is created using microcontroller technology as the heart of the system, the accelerometer as to detect the sudden movement or fall and the Global System for Mobile (GSM) modem, to send out message to the receiver without any participation of the person who needs help. The system designed can detect the accidental fall of people accurately and send a message originally edited to supposed family members. And it can be furthered used in a broad application field. This report covers the introduction of the project which includes the objectives and the proposed plan. The literature review covers the background theory of individual components essentials for the project. The hardware and software design and integration shows the stages advancement of this system. Finally this report concludes with the results and discussion.
