When you create a new IoT project probably you need to connect microcontroller to a battary power source, but if you don’t use a power saving options your battery will run out in no time.
As a lot of IoT microcontroller, WeMos D1 mini have some power saving mode.
The types are modem sleep, light sleep and deep sleep.
A simple method to notify a problem is to use email, It’s very usefully and simple to share, so I created a library to do It. I get some code from GSender a library that It’s quite simple, but not so complete and configurable.
ESP-01 is low cost esp8266 module, with built-in WIFI.
It was created as Arduino WIFI module, but It’s more powerful than an Arduino, than now if you need a little module to control a relay or some simple digital datalogger It’s the best solution.
