Aiming at problem of high power consumption

limited range of alarm and inconvenience for carrying existing in fall detection devices

a fall detection system is designed based on MPU6050

using Arduino and Android.A parallel threshold algorithm based on data fusion is proposed

which achieves accuracy of 97. 6 % and specificity of99. 2 % as shown by the simulation test of five subjects. Experiments show that the proposed algorithm and scheme can achieve accurate detection and timely location and alarming of human body fall

as well as portability.
