Boas,
Então, em Ingles (desculpa!!).
I have finally installed my new weatherstation in the field in Middelburg, Holanda. I am very happy with the following things:
1) The home made sensorshields. They are built according to KNMI standards, zo shielded from direct en indirect sunlight, matte black insides (also the ground plate, which is white on the oustide).
2) The place is absolutely free and according to WMO standards. Nearest bush is at least 100 m away, nearest trees (seen on the foto) at 180 m. everything else is grass, kept low by the horses.
3) the right sensorshield contains a Tinytag Ultra 2 datalogger, which measures with an 0,2 K maximum deviation and 0,001 K resolution. It keeps minimum maximum and hourly temperatures in memory for 1,5 years.
The left one contains an Oregon Scientific 918 TH sensor, which is actually about as accurate (to my suprise) and thus more accurate than my Davis WMII station.
Rain resolution is 1 mm. Will change that into 0,1 mm with another funnel and a device that stores heavy rains, so the sensor can keep track of heavy downpours.
Very nearby this station 2 km or so is a KNMI rainstation. Both recorded 14 mm of rain day before yesterday. Which was a heavy downpour. Accuracy is oke.
Wind...is at 4 m height, which is too low. The speed I measured was 46 km/h while nearby KNMI WIlhelminadorp (also more inland, at 15 km distance in the extreme flat countryside over here) measured a max of 54 km/h. The difference is due to the 6 m height difference.
Barometer (in the house) is installed for 4 weeks and is at 0,5 hPA accurate, again: much to my surprise.
I can easily reach 200 m wireless contact, even with trees in between.
I am having trouble getting meteohub connected to the router of the farmer. I can get everything, but cannot find the WAN IP on the router. Costs me 10-12 hours already, while on two other routers it was only 30 minutes....really too bad! But I will figure it out.
Pictures of the station:
Site from the sky with distance to trees and a dyke (both seen on the pictures):
BTW: I like the diverse stations I have seen here. Nice to see that so many of my fellow Portugese countryman enjoy having meteorology as a hobby and are so active in it.
Best regards,
Jorge
