MEASUREMENT OF DISTANCE OF AN OBSTACLE USING ULTRASONIC SENSOR WITH FPGA

Abstract

This paper presents a new way to measure the distance of an obstacle using an ultrasonic sensor with FPGA. As the wired measurements may not be accurate due to manual errors but here we use non-wired device i.e., ultrasonic sensor to measure the distance of an obstacle that present in front of the sensor. Ultrasonic sensor is interfaced with the FPGA board to decode and display the measured distance of the obstacle.
