| Abstract: | Ultrasonic range-finding sensors usually consist of piezoelectric transducers and transmltting/receiving circuits, and their performances are directly affected by the impedance characteristics of the piezoelectric transducers. For the purpose of getting stronger echoes and extending the effective range-finding distance, the impedance characteristics are analyzed and tested in this paper, and the impedance matching circuit is designed and its functions are testified experimentally. |
