MEMS Accelerometer based Low-Cost Collision Impact Analyzer

Accident impact analysis helps to minimize losses such as death, injuries and property damage due to vehicle collision on road. An efficient impact analyzer is capable of accumulating and processing large amount of data very quickly. Hardware and software both plays important role to collect, process and store large amount of data within a very short period of time. MEMS accelerometers are cost effective and offer better performance with high functionalities compared to conventional piezoelectric accelerometers. The purpose of this paper is to conduct in-depth analyses of low-cost impact analyzer. Hardware and software consideration to implement a low cost impact analyzer (LCIA) are discussed. To simulate the accident, the system has been dropped from a certain height. With time-stamp, the tested data was recorded into microSD card and later the data was analyzed in computer and discussed.
