\u00c7al\u0131\u015fma Prensibi<\/strong><\/p>\n\n\n\n

Dijital s\u0131cakl\u0131k sens\u00f6rleri, farkl\u0131 teknolojilere dayanabilir, ancak en yayg\u0131n kullan\u0131lan sens\u00f6r t\u00fcrlerinden biri “DS18B20” tipi 1-Wire sens\u00f6rlerdir. Bu tip sens\u00f6rlerin \u00e7al\u0131\u015fma prensibi a\u015fa\u011f\u0131daki gibidir:<\/p>\n\n\n\n

    \n
  1. Termal \u0130letkenlik<\/strong>: Dijital s\u0131cakl\u0131k sens\u00f6rlerinin temel \u00e7al\u0131\u015fma prensibi termal iletkenliktir. Sens\u00f6r\u00fcn i\u00e7inde bulunan termal iletken malzeme, s\u0131cakl\u0131k de\u011fi\u015fikliklerine kar\u015f\u0131 duyarl\u0131d\u0131r.<\/li>\n\n\n\n
  2. Dijital \u0130leti\u015fim<\/strong>: DS18B20 gibi dijital s\u0131cakl\u0131k sens\u00f6rleri, bir dijital ileti\u015fim protokol\u00fc kullan\u0131r. Bu protokol, sens\u00f6rden gelen verilerin dijital bir formatta okunmas\u0131n\u0131 sa\u011flar. 1-Wire protokol\u00fc gibi basit bir ileti\u015fim y\u00f6ntemi kullan\u0131l\u0131r.<\/li>\n\n\n\n
  3. S\u0131cakl\u0131k De\u011ferinin Hesaplanmas\u0131<\/strong>: Sens\u00f6r, \u00e7evresel s\u0131cakl\u0131\u011f\u0131 \u00f6l\u00e7er ve bu de\u011feri dijital bir kod olarak sunar. Mikrodenetleyiciler veya bilgisayarlar bu kodu okur ve s\u0131cakl\u0131k de\u011ferini hesaplarlar.<\/li>\n<\/ol>\n\n\n\n
