A fall-detection device based on accelerometer is designed to safely and accurately monitor the user while still allowing complete privacy and security.Considering the characteristic of elderly people

a fall detection device hardware is designed based on accelerometer

using micro-sensors

digital data processing and wireless technologies.By utilizing acceleration values corresponding to the user’s body motion

a robust algorithm is developed to accurately detect a fall.During field experiment and analysis

this detection system can distinguish fall event from normal activities

and raise fall alarm automatically to get a shortened interval of the arrival of assistance.
