Description: Abstract : Principle and structure of ultrasonic distance measurement instrument by master of MCU are intro2 duced. With the control of MCU to operate the time2keeping ,distance from target to original point is gained using product with the time of ultrasonic transmitting both to the target and reflecting back and the speed of ultrasonic which transmits in the air. And system structure ,circuit philosophy and programming are also specified. In the process of data , temperature compensation and adjustment of amendment ammount are used , so the instrument system has features : ease of control , stability of operation , highness of precision and distinctness of programme process ,etc.
Key words : microprocessor control unit (MCU) ultrasonic sensor distance measurement temperature com2 pensation
