## Components

- **Arduino Mega 2560** x 1 ([docs](https://www.farnell.com/datasheets/1674878.pdf?_ga=2.12759806.871556650.1519619484-654667508.1508905608&_gac=1.209399078.1518779130.EAIaIQobChMI97my66Sq2QIV77ftCh01kgA_EAMYASAAEgKPyvD_BwE))
- **Arduino Ethernet Shield** x 1 ([docs](https://docs.arduino.cc/retired/shields/arduino-ethernet-shield-without-poe-module))

## Article

Three current transformers (one per phase) output 0...1V corresponding to 0...30A. The 0...1V signal gets measured by an ADS1115 analog to digital converter. The modules are connected via I2C to an Arduino with an ethernet extension.
