Way cheaper than a guard dog who can use an iPhone, this project will show you how you can use an Adafruit HUZZAH ESP8266 WiFi microcontroller board with a door sensor to email/tweet/text you when your door has opened!

This tutorial will show building a full-fledged IoT project using Adafruit IO and a Huzzah ESP8266, adding sensors, and then connecting it to IFTTT (if-this-then-that) an API gateway that can communicate with Adafruit IO to add tons of connectivity options to your project.
