Wireless Fall Sensor with GPS location for Monitoring the Elderly

Abstract

Fall is the most consequential cause of injury in elderly that may lead to death sometimes, most of the deaths occurs due to the late response after the fall transpires. Elder people living in rural areas face this astringent issue and as the medical centres are very infrequent at those places, doctors cannot attend on them immediately, so this elderly fall detection system provides functionalities to notify the fall information to the server automatically which reduces the burden of caretakers who need to avail them perpetually. The amelioration of low performance utilizing a accelerometer at wrists and the inconvenience of sensor attached to a waist was concentrated on by integrating the efficacious motion sensing technology involved IMU like MPU-6050 which gives digital output from which Acceleration, Velocity and Quaternion data are observed and compared and additionally changing the sensor location from a waist to wrists. The fall detection system server is the web application server; it allows the doctor at medical centre to monitor the real- time fall in the webpage. Once the fall information is received, the server updates the fall information on the page automatically. By this way the doctor who is attending on, can know the health status of his patient immediately by the notification on the webpage whenever there is an emergency.
