Ultrasonic Range Finder AR831

As the ultrasonic point to strong, energy consumption slow the spread in the medium distance, and therefore the instrument is often used in ultrasonic distance measurements, such as range finders and material level measurement instrument and so on can be achieved by ultrasound. The use of ultrasonic testing is often more rapid, convenient, easy to compute and easy to do real-time control and measurement precision to achieve the requirements of industrial and practical, and therefore with the development of mobile robots it has also been widely used.
