Wow, check out this cool AVR ethernet weather station! My original plan was to have sensors for temperature, air pressure and wind. I started a prototype and it worked very well except for the wind measurement part. I have written a separate article about it: wind-vane-ver01.shtml. I plan to improve the wind measurement hardware and add it at a later point in time. For now the weather station has 2 temperature sensors and an air pressure sensor. It works reliable and precise even after several month of testing.
