Get Months of Battery Life from an ESP8266!

EDIT: By using ESP.deepSleep(time to sleep or 0); rather than
ESP.deepSleep(time to sleep, WAKE_RF_DEFAULT); the power usage is even lower, like 0.02mA or 22uA!!! The Arduino sketch has been updated to reflect is change.

By putting an ESP8266 into deep sleep mode you can get months (if not years) of battery life on a single charge. In this video I go through how to do this and show you guys all a cool program to send push notifications to your phone at the same time!
