Operation of Gyro sensor and 3-axis Accelerometer : Scc 1300 gyro combo sensor

By George Mucheru

Abstract

The purpose of this study is to show how Electronics MEMS Technology is able to solve automotive stability problems to eliminate accidents by use of Accelerometer and Gyro-scope sensors. This study shows how MEMs Technology broad portfolio of automotive accelerometers, gyroscopes and other sensors, helps automotive designers tackle the most demanding in-vehicle sensing applications such as roll-over protection, hill start assist and vehicle stability control. The study starts with background information and then focuses more on operation of gyro-accelerometer sensor, SCC1300 sensor. It also provides detailed study of accelerometers, gyroscopes and other MEMS sensors used in the automotive industry. An SCC 1300 demo kit was used for gyro-accelerometer analysis for the purpose of this study. The kit was fastened on to a motorbike, and then interfaced to a laptop running the graphical user interface software, then the motorbike accelerated and the data captured was recorded in a graph. In a continuous acceleration test, the accelerometer gave an output of X=0.17g, Y=0.10g and Z=0.76g [1g=9.8m/s2], while for the same moment the gyroscope gave 0.22°/s. In real applications, these results would be typical inputs to the automotive Electronics control unit (ECU), which when processed is sent to other processes for corrective action. The results compares well with the one printed in the manufacturer’s website
