Automotive Vibration Analysis Using ESP8266 Microcontroller

A significant role in electronics and not only is represented by the vibration’s variable. The paper aims to present an electronic solution for measuring and recording vibrations on a Secure Digital (SD) card. The data collected on the SD card can be used to analyze the condition of the vehicle engine by performing a vibration analysis. The hardware solution is based on an ESP8266 microcontroller, an accelerometer sensor, display and SD memory card. With the proper software the hardware can be turned into an Internet of Things (IoT) solution for future research. This paper covers the implemented hardware solution, real time data reading and processing, data storing using an SD memory card and testing on different car engines. After testing, differences were observed in the vibrations generated by an engine operating in normal parameters compared to a used engine or one with technical problems. Based on vibration analysis a preventive maintenance program can be made for different engines and not only.
