Abstract
This project focuses on the design and implementation of a speed measurement system for moving objects using two infrared (IR) sensors and a microcontroller (such as Arduino). The system works by detecting the time interval an object takes to move between two fixed positions. By knowing the distance between the sensors and measuring the time taken, the speed is calculated using the basic formula: Speed = Distance / Time. This system is useful in applications such as monitoring vehicle speed, sports training, and industrial automation. It provides a low-cost, accurate, and real-time solution for measuring speed.

Introduction
Speed measurement of moving objects plays a crucial role in various domains such as traffic monitoring, sports, and robotics. Traditional methods using radar or LIDAR are often expensive and complex. This project proposes a cost-effective solution using simple IR sensors and a microcontroller. By placing two IR sensors at a known distance apart, the system measures the time taken by an object to move from one sensor to another. This time data is used to compute the speed. The system is portable, simple to implement, and suitable for educational, experimental, and practical applications.
