About this project

Brief

This project consists on a "Smart Energy Meter" that is capable to identify and segregate loads and appliances connected to our house grid by analysing their harmonics behaviour extracted from their current and voltage raw signals, also, with some custom code, the microcontroller shares the inferences results and energy measurements to a server in the cloud using a WiFi Notecard
