Asa cum spune si titlul, doresc sa realizez in cadrul scolii de care apartin un contor digital cu Arduino de curent, in timp real. Astept pareri pro si contraq din partea voastra in legatura cu chestia care urmeaza s-o pun pe picioare.

Mai jos aveti link-uri utile care va pot ajuta daca vreti si voi sa va faceti asa ceva, gasite de mine dupa cateva nopti de sapat prin adancurile Google-ului :ras:

Curentul maxim o sa fie atat cat o sa suporte si senzorul, 30A. O sa-l fac sa fie doar pentru prezentare, nu cred c-o sa-l folosesc acasa, poate doar o ora doua sa vad daca citeste la fel si contorul de la furnizor :freaza:De ce ar fi greu de facut?

modulele sunt chinezesti  :banghead:  dar ACS712 e ok :dsgfds ... e suficient sa te uiti in datasheet-ul lui: http://www.allegromicro.com/~/media/Files/Datasheets/ACS712-Datasheet.ashx (si  cred ca textul asta e suficient:"2.1 kVRMS minimum isolation voltage from pins 1-4 to pins 5-8") 

 

eu l-am prezentat in 2 articolase:
