Abstract—Distance measurement of an object in the path of a person, equipment, or a vehicle, stationary or moving is used in a large number of applications such as robotic movement control, vehicle control, blind man’s walking stick, medical applications, etc. Measurement using ultrasonic sensors is one of the cheapest among various options. In this paper distance measurement of an obstacle by using separate ultrasonic transmitter, receiver and a microcontroller is presented. The experimental setup and results are described and explained.
Index Terms—Corrections in distance measurement, distance measurement, microcontroller, sewer blockage detection, sewer inspection system, robotics, and ultrasonic sensors.
