Matuosime generatoriaus temperat\u016br\u0105. Daviklis bus termopora, \u012fmontuota pa\u010diame generatoriuje. Pabandysime analogin\u012f termoporos signal\u0105 konvertuoti \u012f skaitmenin\u012f.<\/p>\n

Kaip visada geras Kam to reikia? Ir atsakymas: paprast\u0173 sprendim\u0173 mes neie\u0161kom. O tiksliau: pritr\u016bkom analogini\u0173 \u012f\u0117jim\u0173 Arduino modulyje. Teks naudoti skaitmeninius. Yra chipas MAX31856: Precision Thermocouple to Digital Converter
\nwith Linearization. Tarsi jus turi visk\u0105 ko reikia. Lemonoje galima j\u012f u\u017esakyti, kaina 9 \u20ac. Paie\u0161kokim dar. gal rasim ka\u017ek\u0105 i\u0161 kompiuterinio lau\u017eo.
