Since some time I have been to develop a meteorological station for the Free Flight Club of Caramulo with an Internet connection to update in real time….

This spaghetti of wires is only one Arduino (changed to 20 MHz) with a network card based on chip ENC28J60 (better than Wiz official), is so linked only to tests of UPTIME and reliability. So far has an uptime of about 2 months and, taking into account that my cat engraçou with temperature sensor…

The first version I made this station is based on the Arduino UNO with the official network adapter (The Wiz between 25 and 50 euros) – A huge waste of money, the second is based on the same in the arduino but this time with a much cheaper (between 14 the 30 euros) and without doubt much more reliable

Now, I am trying to remove all of the potential problems that can happen to me – that being said the main source of problems is the own arduino… Result: use the ATMEGA328 for its ease of programming and information quantity, but on a plate made by me, thus reducing costs and making the project a lot more functional.
