From my first experience with Arduino Duemilanove in late days in 2010 it was love at first sight!

I finally had the possibility to interact with a microcontroller in a simple way, maybe rough but for sure cost effective.

During 2012 I built my first wind datalogger, solar powered, as told here. It worked fine, even tough it was simple and not so much energy saving...but a simple 2W panel was enough, and I was able to analyze data and be sure there is enough wind.

The anemometer was a Vortex one, firstly: a simple reed closing each turn. Secondly I chose a Deltatronic one, cheaper and sturdy.

A Seeedstudio Solar shield, with a sketch able to send Arduino in deep sleep made it possible to collect data every 30 seconds or 60 seconds, far away more than commercial wind datalogger, and save data every 2 minutes on an SD card. It worked fine for more than one year, attached are a sample log file and the corresponding wind data analyzed, and the Arduino sketch I'm using in Zanzibar in a similar way by now.

The bad: you have to send someone you taught before to go to datalogging pole mount, extract SD card, copy on a PC and send by email. Not so diffucult, not so simple.

I tried with an Arduino Yun with a USB pendrive with a SIM: it worked, but it was not so cost effective, and power hungry.

Last year I joined a crowdfunding campaign in order to obtain a microcontroller as simple as Arduino, with an international M2M SIM card.

Now it is time to send wind data over the net!
