LABORATÓRNE CVIČENIE č. 32 Meranie teploty s termočlánkom typu K
 Ciele merania  (Úlohy) : 
a) Oboznámte sa s hardvérovým a softvérovým riešenia meracieho prípravku
b) Vykonajte merania teploty vody pri jej rôznych hodnotách
c) Overte výpočet teploty z výstupného datastreamu interfejsového obvodu MAX6675
d) Overte lineárnu charakteristiku snímača teploty na báze termočlánku typu K
