ESP8266 GMail sender

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.ESP8266 GMail sender

Before we begin
Required hardware:
  1. Any ESP8266 (I’m using ESP8266-07 ebay link).
  2. In my case USB UART Board(I’m using FT232RL FTDI Serials Adapter Module ebay). Not needed if your board has usb port.
  3. Some jumper cables.
  4. WIFI router of course.

List may be incomplete.
Required software:

  1. Arduino Software
  2. Arduino core for ESP8266 WiFi chip
  3. Sketch with project and test code (

Step 1: Gmail Account Setup

We are going to use SMTP to send messages.
Using SMTP Authentication we provide only email and password,
by default Google uses more complex verification methods so we need to change settings.
Go to your Google account settings and enable “Allow less secure apps” at the bottom of the page.
This mean apps only need your email and password when login to your gmail account.
If you concerned about security, just use different account.
