Product characteristics:

US-015 ultrasonic ranging module can provide2cm-400cm non-contact distance sensing function, ranging accuracy can reach0.5mm, including the transmitter, receiver and control circuit, it is a kind of piezoelectric sensor, which is made by the electroscaling phenomenon. The piezoelectricity material sections (such as quartz crystal, piezoelectricity ceramic, lead titanate barium and the like) to apply an alternating voltage, they are made to produce the electrostrictive vibration ultrasonic. When the frequency of the applied alternating voltage is equal to the inherent frequency of the wafer and resonance is generated, then the ultrasonic wave generated is the strongest. Piezoelectric ultrasonic receiver generally uses the inverse effect of ultrasonic generator to work. Its structure is basically the same as that of Ultrasonic Generator. Sometimes, the same transducer is used as both generator and receiver. When the ultrasonic wave acts on piezoelectricity wafer, the wafer stretches and stretches. Alternating charges are generated on the two interfaces of the wafer and then converted into voltage, which is amplified and sent to the measuring circuit, and finally recorded or displayed.
