ultra sonic range finder
The ultrasonic ranger is a sophisticated device that uses sound waves to measure the distance of an object. Primary functions of this such as testing the proximity of things, observing whether obstacles exist before a car gets there and providing precise information for distance. Technology of the ultrasonic ranger includes its high-frequency sound waves and measurement of time taken to get an echo back, so that it can calculate distance with precision. This technology is compact, tough and often has sophisticated algorithms to cope with many environmental factors. A multiplicity of applications are possible for the ultra sonic ranger, including autonomous vehicles and robotics as well as industrial automation and parking assistance systems.
