JSN-SR0T4-2.0 ultrasonic distance measuring module can provide 20cm-600cm non-contact distance sensing function, ranging accuracy up to 2mm; module includes transceiver ultrasonic sensor and control circuit. It is a piezoelectric sensor made using electrostrictive phenomena. An alternating voltage is applied to a piezoelectric material slice (for example, a quartz crystal, a piezoelectric ceramic, a lead titanate titanate, etc.) so that it generates electrostrictive vibration and generates ultrasonic waves. When the frequency of the applied alternating voltage is equal to the natural frequency of the wafer and resonance occurs, the generated ultrasonic wave is the strongest. Piezoelectric ultrasonic receivers generally use the inverse effect of ultrasonic generators to work. Their structure is basically the same as that of ultrasonic generators. Sometimes they use the same transducer as both the generator and the receiver. When the ultrasonic wave acts on the piezoelectric wafer to make the wafer expand and contract, an alternating charge is generated on the two interfaces of the wafer and then converted into a voltage and then amplified and sent to a measuring circuit for recording or displaying.
