Abstract-Every 11 seconds, an older adult is treated in the emergency room for a fall; every 19 minutes, an older adult is injured from a fall. Falls are the leading cause of fatal injury and the most common cause of non-fatal trauma- related hospital admissions among older adults. If the elderly fall, it will be difficult for them to request for help. The main objective of this project is to design a fall protection sensor system at affordable cost for the elderly. The system can acknowledge a free fall such that the fall can be protected by an inflated air bag. The implementation combines both hardware and software that work seamlessly in detecting and protecting a fall at home. The input from the 3-axis sensor accelerometer (ADXL335 orADXL345) and gyroscope will be fed to the microcontroller which will detect the fall and further input to the driver circuit to inflate the air bag according to the algorithm coded using EMBEDDED C
