Abstract: Measuring distance between two objects accurately is very difficult task. Generally we have to carry a measuring apparatus with us all for measuring the distance between two objects. Many systems are designed for measuring the distance but they all lack the accuracy, such as ultrasonic sensor based distance measurement unit. Which uses ultrasonic sensor and a microcontroller for measuring the distance between two objects after measuring the distance it displays the information on a display screen connected with the microcontroller. But the measured distance is not accurate because there are many factors which affects the accuracy of the system by affecting the speed of sound in air. In this paper these factor are discussed and what changes are needed for improving the accuracy of system.
