The increasing number of road accidents caused by undetected path holes and vehicle imbalance poses a significant threat to road safety.

This paper presents the design and implementation of an Automatic Path Hole Detection and Alert System using Raspberry Pi Pico as the microcontroller.

The proposed system is mounted on a robotic vehicle equipped with an ultrasonic sensor and an accelerometer to detect path holes and vehicle imbalance, respectively.

Upon detection, the system will send SMS to the concerned user and also triggers a buzzer and a red LED to alert the user of potential hazards.

This real-time detection and alert mechanism aim to reduce accidents and enhance vehicle safety, especially in environments with poor road conditions.

The effectiveness of the system is validated through a series of experiments, demonstrating its potential for practical deployment in autonomous vehicles and road safety monitoring systems.

• Detect Path Holes: Utilize an ultrasonic sensor to accurately detect path holes on road surfaces in real-time.
• Identify Vehicle Imbalance: Employ an accelerometer to monitor and identify any imbalance in the vehicle caused by uneven road surfaces or sudden changes in terrain.
• Provide Immediate Alerts: Implement a buzzer and red LED to instantly alert the driver of detected path holes or vehicle imbalance, enabling prompt corrective actions.
• Enhance Road Safety: Reduce the risk of accidents and vehicle damage by providing real-time hazard detection and alerts to drivers.
• Develop a Cost-Effective Solution: Use Raspberry Pi Pico as the microcontroller to create an affordable and efficient system for road condition monitoring.
• Facilitate Easy Integration: Design the system to be easily integrated into existing vehicles or autonomous systems for widespread application.
• To send the alert messages to the concerned person.
