Ola,
Lamento, mas em Ingles....
This station is what many people have been wating for I think. It has most of the capabilities of the Davis Vantage Pro 2 but at a much lower price!
If you include a UV sensor, it will cost you 399 euro in Germany (the price will surely drop late ron this year or next year, but it doesn't have to). I saw the same price in France..
Look at the features:
- Solar panel for power
- Oregon Scientific Protocol 3.0 100 metres 433 Mhz datatransmission
- Temperature/hygrometre sensor
- Windsensor
- Rainbucket
- Optional UV sensor
- Barometer
- Including mast
- Touchscreen monitor
- Datalogger for intervalls between 1 minute and a few hours. 15 minute intervall gives you 439 days of datalogging capacity!![Thumbs Up :thumbsup: :thumbsup:](/forum/styles/meteopt/smilies/thumbsup.gif)
- USB connection
- Flash ROM (so you do not lose data when atteries might fail).
- You can add upto 10 sensors, some of which can easily be build into a solarduration sensor (using the right software).
- The radiation shield seems bad,so build or buy another one.
Oregon says temperature is measured with a 1 K (C) accuracy. Barometer: +/- 10 hPa (mbar), rain 1 mm, hygormeter +/- 5%.
But I have read some german test of the WMR-100, which is essentially the same unit when it comes to accuracy. In reality, the temperature sensor is within 0,1 K of a calibrated thermometer. The barometer is within 1 hPA and raingauge indeed is 1 mm...
In another test, the same result: barometer +/- 1 HPA, thermometer +/- 0,3 K deviation at max!, Hygromter: 1 % devitation form a calibrated hygrometer. Windsensors are performing very well indeed.
Other Oregon Scientific instruments have the same good test results.
I frequent a German forum very often. There, a guy who has a professional weatherstation from the Deutsche Wetterdienst also has an Oregon Scientific. He also notes that there are virtually no differences.
Besides: all test shows that the transmission is very, very reliable. This is also noted on many fora by many users.
You can buy a large gauge in some hobbyshops (20 cm diameter, tomake it 0.25 mm precise ( Ithink).
I will buy this one and test it. I think, if it lives up to Oregon Scientifics standard of accuracy it is a very tough competitor of Davis. And I think Davis is oke, but some competition is needed.
