Weather stations

Home weather stations JVD forecast weather with barometric sensor that registers any pressure changes in a given area. The pressure in a valley differs from the one on a peak of mountains. At the same absolute pressure, somewhere will be a nice weather and somewhere won’t. That’s why we use a relative pressure – for union of pressures in different elevations above sea-level. Thanks to this simplification it is possible to observe globally all weather changes. If the altitude on the weather stations is possible to set manually, we can observe actual weather pretty much right after turning the station on. Otherwise the station has to get all the information about the ways up and down of the pressure at first, so we can say where is the maximum range that shows in what area will be the weather forecasted. This process can last for several days if the weather stays the same. The value of the pressure is not as important as the change or the rapidity of this change. When the increase is slow we can look forward to nice weather, on the other hand the fast decrease may mean a storm. Because the weather forecast shows animations on an appliance JVD it doesn’t have to correspond with the situation behind the window.
The newest models of digital stations and thermometers JVD show besides absolutely accurate radio controlled time and date also air pressure, moon stage, very often they have remote sensors that measure temperature and relative humidity of the air up to 75 meters in an open space. High quality elaboration and modern design are matters of fact of all products JVD.
