Ultrasonik Sens\u00f6r\u00fcn Bile\u015fenleri<\/h3>\n

Bir ultrasonik sens\u00f6r genellikle bir verici, bir al\u0131c\u0131 ve bir kontrol devresinden olu\u015fur. Verici, piezoelektrik bir kristal kullanarak elektrik enerjisini ultrasonik dalgalara d\u00f6n\u00fc\u015ft\u00fcr\u00fcr. Al\u0131c\u0131 ise, geri d\u00f6nen yank\u0131y\u0131 alg\u0131lar ve bunu elektrik sinyaline d\u00f6n\u00fc\u015ft\u00fcr\u00fcr. Kontrol devresi, vericiyi tetikler, yank\u0131n\u0131n al\u0131nma s\u00fcresini \u00f6l\u00e7er ve mesafeyi hesaplar.<\/p>\n

Verici taraf\u0131ndan \u00fcretilen ultrasonik dalga, havada yay\u0131l\u0131r ve bir engele \u00e7arpt\u0131\u011f\u0131nda geri yans\u0131r. Bu yans\u0131yan dalga, yank\u0131 olarak adland\u0131r\u0131l\u0131r.
