Road Condition Monitoring with Use of MEMS Based Unit

The paper deals with the design and use of smart unit for real-time road condition monitoring. The basis is three-axis accelerometer, gyroscope and magnetometer based on MEMS technology, which provides its data to the main microcontroller. As a communication interface for data providing, the high-speed CAN bus was used. The reason was an easier way to implement in the car and achieve a higher frequency of data provision. The result of this work is the determination of the critical sections of the measured route.
