High-precision Ultrasonic Ranging System

摘要：

The ultrasound is easy to transmit and has good reflection. Its speed is far less than the speed of flight. So this paper designs an ultrasonic ranging system based on STC89C52RC. This system can be effective in the range of about 372 cm. After repeated test, the measurement error can be less than 1 cm. So this system can be applied to intelligent avoidance and vehicle transportation and other systems.

关键词： SCM ultrasound send receive ranging temperature compensation.
