| Abstract: | Based on the Hall-effect sensor the present paper introduces an overall design scheme of speed measurement and alarm system controlled by MCU. The design focuses on hardware structure, software implementation, physical ideas and working principles. The system was used to conduct experimental testing and validation. The result shows that the system＇s accuracy is high and alarm functions are sensitive. We recommend that this system be installed in all wheeled motor vehicles. |
