The aged are faced with increasing risk for falls. The aged have the easily fragile bones than others. When falls have occurred, it is important to detect this emergency state because such events often lead to more serious illness or even death. The system, for detection of emergency situation, was developed using bi-axis gyro sensor in this paper as follows. The signals were acquired from the bi-axis gyro sensor, and then transmitted to the PC through bluetooth module. This system can classify the human activity, and also detect the emergency state like falls. The our study was performed to detect the correct falls. The output of gyro sensor signal was compared and evaluated by changing a various posture after attaching a bi-axis gyro sensor module on the chest. The newly developed system has some important features such as portability and convenience. One of the main advantages of this system is that it is available at home healthcare environment. The implemented system can detect the falls. so it will be widely used in emergency situation.
