Road conditions play a crucial role in ensuring the safety and comfort of commuters. Potholes, humps, and uneven road surfaces pose significant risks, leading to accidents, vehicle damage, and increased maintenance costs. This project aims to develop an automated road condition monitoring system using an Arduino Uno as the main controller. The system incorporates ultrasonic and IR sensors to detect potholes and humps, while an ESP32-CAM module captures images of detected road irregularities. A GPS module determines the exact location of these hazards, and a GSM module sends alerts with location details to a registered mobile number. A MEMS sensor is used to detect uneven road surfaces and abnormal vibrations. When the system detects potholes, humps, or uneven road conditions, it automatically stops the vehicle and alerts the driver through a buzzer. Simultaneously, the ESP32-CAM captures images of the affected road area and stores them on an MMC/SD card for future reference. All detected data, including images and GPS coordinates, are also stored on the SD card for analysis and maintenance purposes. The current system status and detected conditions are displayed on an LCD screen, providing real-time updates to the user. The entire system is programmed using Embedded C language, ensuring efficient and automated operation. This smart road condition monitoring and maintenance system can significantly improve road safety, support timely road maintenance, and reduce accident risks caused by damaged or uneven road surfaces.
