Today I'll show you how to build this Arduino based energy meter. This is Part 2 where I'll solder up the boards and get ready for the final custom power bank. The meter can measure power and energy in aH in 2 directions. It uses a Hall Effect sensor for current and a precision voltage divider for voltage.
