Falls in elderly people have been recognized as a major health problem in aging population. Falls are identified as a major health risk not only for the elderly but also for people with neurodegenerative diseases, such as epilepsy, and are considered as a major obstacle to independent living. Fast detection of falls would not only decrease the health risks by enabling quick medical response; but also make independent living a safe option for the elderly. In this paper we propose e-Fall detector consists of the development of an accurate, accelerometer based fall detector. The device worn on the leg uses a fall detection algorithm, which senses the body orientation of the wearer. An Inertial Measurement Unit (IMU) consist of an accelerometer, a gyroscope and a magnetometer. There are distinct kinematics characteristics during falls, accelerometer sensor senses the different patterns of fall and gyroscope detects the orientation change of the body when the patient's body fails to get aligned with the sensor. The combined use of an accelerometer and gyroscope helps in distinguishing the sudden fall from the normal day-to-day activities which could be achieved by a single sensor with the appropriate kinematics measurements and detection algorithms. A microcontroller interface allows the setting of threshold values after prior calibration of the accelerometer. When the orientation change of the patient is detected, the percentage of fall is calculated from the readings of the accelerometer. Once it exceeds the threshold value, the microcontroller initiates an alarm to represent the elderly patient's fall. This helps the caregivers to prevent unnecessary injury of elderly people
