Ampermetru pe portul serial? PLEASE HELP :)

Recommended Posts

Am nevoie (sau ma rog, mi-as dori) de un ampermetru pe portul serial. Asta fiind cea mai simpla situatie. Vreau sa-l folosesc sa vad cat consuma un device alimentat la 230V AC.


Daca nu e cu suprare, as prefera ceva de genul:


/ OUT1 cu Ampermetru1 \IN -> Voltmetru -> OUT2 cu Ampermetru2 -> port serial                 \ OUT3 cu Ampermetru3 /
Practic o cutiuta in care sa intru cu 220V si sa ies cu o seriala & 3 prize 220V. Pe seriala sa pot citi tensiunea de intrare & amperajele pe cele 3 linii. Softul l-as face in principiu, nu ar fi o problema, pe cand partea de voltmetru / ampermetru ma depaseste total.


Any ideeas? TX.
