Since writing up instructions on how to build a simple Arduino home energy meter which measured the energy consumption for a single phase, I’ve had a number of people ask about modifying it to be a 3 phase energy meter. While there is a range of commercially available single phase energy meters available, the 3 phase meters aren’t nearly as common and tend to be quite expensive. So I decided to take the time to build a 3 phase energy meter and fix up a couple of areas in t...

Hello and welcome to my first Instructable. I will show you how to send emails from any ESP8266 wifi module using Gmail server.This instructable relies on Arduino core for ESP8266 WiFi chip, which makes a self-contained microcontroller from it (no need of AT commands and master devices). You can connect sensors and get notified by email about changes.Before we begin Required hardware: Any ESP8266 (I'm using ESP8266-07 ebay link). In my case USB UART Board(I'm using FT232RL FTDI Serial...
