    What’s the ultrasonic ranging transducer

    One can hear that the sound is generated by the vibration of the object. Its frequency of transducer for distance is in the range of 20HZ-20KHZ, the ultrasonic wave is more than 20KHZ, and the infrasound wave is lower than 20HZ. Commonly used ultrasonic frequencies are tens of KHZ-tens of MHZ. Since
