I've not had meteohub running for a few weeks so it is about time to introduce it here :-)
The only difficult thing was getting the wind sensor to the top of my mast :-)
Picture on this page http://majland.org/blog/?p=136 (in danish)
It is about 7,5-8 meter above ground and not completely free from sorrounding buildings and trees. But the best place i could place it.
Here is an airphoto http://www.majland.org/hvolris/20021009_Luftfoto.jpg
The mast is on the upper right corner of the white building in the middle of the picture.
There is a burial mound to the west (covered by trees)
The setup has been working almost 100% I've had some weird data logged on two occasions. But not been fast enough to see whether the data was consistent between the console and meteohub.
I'm still playing arround with which graphs i want to generate but the current is here
http://majland.org/weather/ or integrated in my blog http://majland.org/blog/?page_id=174
Besides the weather staion i've also connected som dallas semicondutor 1-wire temperature sensors. Back in 2001 i bought a preprogrammed microntroller from http://www.phanderson.com/ so i from a normal seriel port could get readings
Via an USB2Ser converter it is now hanging on teh slug. The data collection is not done by meteohub (would be nice trough) but just by a small c program called from the crontab. Similar i call gnuplot and get graphs like: http://majland.org/weather/1wire.png
