1. Ultrasonic transducer, what kind of pulse does it need to generate or obtain ultrasound? And, how is the resonance frequency determined?
In an piezoelectric ultrasonic transducer, the pulse required is a high-frequency pulse signal, and is determined by its driving frequency. As for the determination of the resonant frequency of the transducer, the manufacturer of the product can be directly inquired, or the impedance analyzer can be used for detection, and the circuit can be used for detection. You can select a suitable method according to the actual situation.
2. How to detect the impedance of the ultrasonic transducer? And, what is the impact of the capacitance of the ultrasonic transducer?
Ultrasonic transducer distance is better than the impedance of the transducer. If it is to be detected, it is relatively simple to use an impedance analyzer. If you don't have one, you can take a look at the acoustic measurement experiment, which has some corresponding methods for specific operations. As for the capacitance of the ultrasonic transducer, because it is only the performance, it will affect the specific aspect of the transducer matching.
3. What is the operating voltage of the ultrasonic transducer? The operating voltage of the arduino ultrasonic range sensor model cannot exceed 120 volts. Moreover, on the receiving signal of the transducer, it mainly depends on three specific aspects of its emission voltage, emission distance, and reflective surface in the transducer.
