The frequency of the ultrasound that people can hear is 20Hz~2KHz, that is, audible sound waves. The sound beyond this frequency range, the ultrasound below 20Hz is called low-frequency sound wave, and the ultrasound above 20KHz is called ultrasound (ultrasound), the frequency of general speaking .T

Product IntroductionThis URM06 ultrasonic module distance measuring sensor is designed by DFRobot based on senscomp's 6500 ultrasonic electrostatic transducer, with a measuring distance of up to 10 meters. It is the ultrasonic sensor with the longest measurement distance, the smallest angle and the

The propagation path of the ultrasonic waves is called a channel. The additive noise of the channel is mainly determined by the undulating noise, ultrasonic transducers sensor in turn can be regarded as Gaussian white noise. Since additive noise is considered to only affect the reception of the sign

When ultrasonic distance measurements transducers are made on the tree barriers in transmission corridors, most of the crowns in the corridors are not a smooth surface, the canopy is non-specular reflection of the signal from the ultrasonic detector, ultrasonic absorption effect is large, and the si
