摘要:By analyzing the causes of ultrasonic distance measurement error, through the use of temperature compensation, and increasing the measured time interval to the microsecond level, ultrasonic ranging circuit can achieve the millimeter level. After the circuit design and construction, the ultrasonic range finder was calibrated from 1cm to 21cm. The measurement results show that in the scope of work, the linearity reached 0.999623; the measurement of the ultrasonic range finder achieved the millimeter level. © (2012) Trans Tech Publications, Switzerland.
