Abstract— Multiple tri-axial acceleration sensor devices for joint sensing of injured body parts, when an accidental fall occurs. The model transmitted the information fed by the sensors distributed over various body parts to the computer through wireless transmission devices for further analysis and judgment, and employed cognitive adjustment method to adjust the acceleration range of various body parts in different movements .The concept of a fall is in the common sense, it is difficult to describe it precisely, and thus to specify its means of detection. If person was injured, he/she will take some time to recovery and then they will try to walk, at that time there are lots of possibilities to fall down, which we can monitor in receiving side by RF receiver. The accelerating sensors values goes abnormal then alert system (buzzer) will alert in the receiving side .The main focuses on designing a system that prevents a patient from falling down when he/she is unconsciousness. Two accelerating sensors are used to detect the position of patient who has met an accident and these sensors can be placed at different places of the body. If any abnormal activity occurs in any region, AIRBAG will be opened to prevent the person from falling. This information will be displayed in Liquid crystal display as well as PC. Front and Back fall detection is detected using x axis of accelerating sensor and Left and Right fall detection is detected using y axis of accelerating sensor.
