3pcs US-100 Ultrasonic Ranging Module with Temperature Compensated Sensor Dual Mode Serial Port

Characteristic The US 100 ultrasonic ranging module can provide 2cm 450cm non contact distance sensing function wide working voltage self contained temperature sensor to correct the ranging result and also has GPIO serial port and other communication methods The dog is stable and reliable The module includes a transmitter receiver and control circuit which is a piezoelectric sensor that is fabricated using electrostrictive phenomena An alternating voltage is applied to the piezoelectric material S lice such as quartz crystal piezoelectric ceramic lead bismuth titanate etc to cause it to generate electrostrictive vibration to generate ultrasonic W aves The resonance is generated when the frequency of the applied alternating voltage is equal to the natural frequency of the wafer and the ultrasonic W ave generated at this time is the strongest Piezoelectric ultrasonic receivers generally operate using the inverse effect of an ultrasonic generator The structure is basically the same as that of an ultrasonic generator and sometimes the same transducer is used as both a generator and a receiver When the ultrasonic W ave acts on the piezoelectric wafer the wafer is stretched and contracted and alternating charges are generated at the two interfaces of the wafer and then converted into a voltage and amplified to be sent to the measuring circuit and finally recorded or displayed Electrical parametersUS 100 ultrasonic ranging moduleOperating VoltageDC 2 4V 5 5VQui
