Abstract

The World Health organization (WHO) indicated that falls are the second leading cause of unintentional injury, deaths for those over 65 years old worldwide. Non-fatal injurious falls can not only cause disability or functional impairment, but also have psychological effects that reduce the range of Activities of Daily Living (ADLs).A combination of sensors such as accelerometer and ultrasonic sound sensor is a cost efficient method for fall detection. Arduino boards are used to detect the fall events based on threshold values. A pair of RF transmitter and receiver is used for wireless communication. Moreover in case of emergency sending an alert to the caregiver would help in timely medical aid. When the microcontroller in the Arduino board senses drastic changes from the threshold values of the sensors outputs, an emergency alert is sent as SMS to the caregiver through a GSM.
