摘要：

ultrasonic ranging system USES AT89C51 as the main controller, the dynamic scanning method is used to implement LED digital tube digital display, complete the ultrasonic driving signal with single-chip microcomputer timer. Ultrasonic directivity is strong, energy consumption slow, in the medium transmission distance is farther, thus the ultrasonic often used for distance measurement.
