Abstract
In this design, a brake pad detection system is developed using the microcontroller STC89C52 along with a potentiometer and ADC0832 module to measure the thickness of the brake pads and provide alarm functionality. The system measures the thickness of the brake pads and triggers a sound and light alarm when the thickness falls below the user-defined minimum value, indicating the need for replacement.During the research and design phase, the STC89C52 microcontroller is chosen as the core controller of the system. It is combined with a potentiometer and ADC0832 module to accurately measure the thickness of the brake pads. Users can conveniently set the minimum thickness value by adjusting the potentiometer to meet the requirements of different brake pads. Additionally, an LCD1602 display module is used to present the measured data visually to the user.The design and implementation of the brake pad detection system were successfully completed. Experimental results confirm that the system can accurately measure the thickness of the brake pads and trigger a sound and light alarm when the thickness falls below the minimum value, ensuring safe vehicle operation. The significance of this project lies in providing a simple and practical solution for brake pad detection, enabling timely monitoring of brake pad wear for vehicle maintenance personnel and preventing accidents caused by worn brake pads. Moreover, by utilizing a microcontroller and related modules in the design, the project showcases the potential application of microcontrollers in the field of vehicle safety, providing valuable references for research and development in related areas.
