Smart home for elderly care using optimized number of wireless sensors

We describe a novel in-home monitoring system designed to for elder-care application. The statistics shows that there is increasing number of elderly people around the world and this isn´t going to change. In developing contries like India, because of growing busy life style, many elderly people are being forced to live alone or put in a rest home or other sheltered living arrangement by their children. Causing the elderly vulnerable and losing their independence. We developed a smart-system consists of optimum number of wireless sensors that includes current, bed, and water flow sensors. The sensors provide information that can be used for monitoring elderly by detecting abnormality pattern in their active daily life. The system will generate early warning message to care giver, when an unforeseen abnormal condition occurs. It will also, analyze the gathered data to determine residents behaviour. Instead of using many number of sensors, the importance of positioning the optimal number of intelligent sensors close to the source of a potential problem phenomenon, where the acquired data provide the greatest benefit or impact has been discussed.
