Design and Construction of Vehicle Speed Detector Using IR Sensor and ARDUINO Microprocessor

This project focuses on the design and construction of a vehicle speed detection system using infrared (IR) sensors and an Arduino-based microcontroller (Atmega328). The system aims to enhance road safety by monitoring and reporting vehicle speeds on highways, particularly in areas prone to accidents due to over-speeding. With the increasing rate of road traffic accidents caused by reckless driving, especially on highways, this system serves as a preventive measure by alerting drivers when they exceed the designated speed limit. The proposed system utilizes two IR sensors placed at a fixed distance to calculate the speed of a passing vehicle based on the time taken to move between the
sensors. The Atmega328 microcontroller processes this data and displays the calculated speed on an LCD screen. A preset button allows users or traffic personnel to set the maximum allowable speed.When the detected speed exceeds this set limit, an audible alarm is triggered to alert the driver or the monitoring authority. This system is particularly beneficial for use by highway traffic enforcement agencies, as it provides real-time feedback and can help in monitoring traffic compliance. The simplicity, affordability, and accuracy of the design make it suitable for deployment in rural and urban highways alike. Overall, the project demonstrates a practical application of embedded systems and
sensor technology in promoting safer driving habits and reducing road traffic accidents
