• Single chip microcomputer of ultrasonic sensor

  Ultrasound refers to mechanical waves with a frequency higher than 20 kHz. In order to use ultrasonic waves as a detecting means, it is necessary to generate ultrasonic waves and receiving ultrasonic waves. The device that performs this function is an ultrasonic sensor, which is customarily called a

• 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

• Advantages and disadvantages of ultrasonic sensors

  A pulse (emission wave) generated by the high-frequency pulse generator is applied to the ultrasonic sensor probe to excite the piezoelectric crystal to oscillate to generate ultrasonic waves. Ultrasonic waves propagate to the inside of the workpiece at a certain speed. A part of the ultrasonic wave
