Weerstation

Davis Pro 2 with UV and Solar

Dit station maakt gebruik van een -Davis Vantage Pro Plus- weerstation. De gegevens op deze site worden door WDconsole geproduceerd. Het station bevat een anemo of windmeter, neerslagmeter, een UV-meter, een zonnestralingsmeter en een thermo-hydro sensor 24/24 actief belucht en geplaatst in de meest optimale positie voor de meest correcte gegevens. Het station stuurt zijn data wireless door en wordt aangedreven door zonnepanelen, met een back-up van 48 uur door middel van een 3.6V batterij. Een MSI laptop met een Intel(R) Core(TM) i7-4710HQ CPU @ 2.50GHz en 32 Gb geheugen verwerkt de data. We hebben onlangs een fijnstofmeter toegevoegd aan onze meetinstrumenten, zie onder tab -luchtkwaliteit-
