Energy Monitor Shield V2

Expansion

Additionally EM Shield v2 can be connected to any device using i2c Grove-compatible connections (sensors, displays, etc.). EM Shield v2 was designed to be fully compatible with?Ethernet Shield (Wiznet 5100 + SD)?- so you can use these two together Schild to create even more advanced device monitoring electricity (logging on SD-card and presenting the data on a web page).
