Odpověď na: Arduino ThinSpeak Měření teploty ze čtyř míst
arduino nano+DS18B20+enc28j60
enc28j60 CS pin je na arduine 8
senzory sa daju upraviť ine ale ak vyhodnotenie merania je ine tak treba len upraviť kod na zistenie hodnoty na senzore
pozri tu, teraz nie je napojene meranie , je to len stara historia

arduino 2x 1-wire bus 4x ds18b20 thingspeak
4sensory 2x na pine 6 a 2x pine 7 —môžete dať všetky štyri na jeden Pin a zmeniť kod
dal som na 2 piny kvôli parazitnym väzbam na dlhom kabli, lebo nemeralo vždy
arduino načita teploty z Pinu 6/7
samozrejme treba upraviť kod:
pridať adresy čisiel, môžete si zmeniť nazvy a zadať kľuč pre THINGSPEAK
