More information about installing weather station here This way, weather station can be placed in direct sunlight, with the thermometer located inside the shelter. The thermometer is at least 15 meters from the nearest paved surface.If the thermometer is placed above grass, again, it should be at least 1.5 meters above the grass surface.If the thermometer is placed on a roof-top, make sure it is at least 1.5 meters above the roof-top.The thermometer receives plenty of ventilation and is not blocked from the wind.The thermometer sensor never receives direct sunlight.Meteorologists define temperature as the temperature in shade with plenty of ventilation.

Weather station is powered from solar panel. The standard wind measurement should be taken at 10 meters above the ground. Weather station should have good 'fetch', or distance from any other tall object. If you place your weather station in an alley, you could very well get a wind tunnel effect on the anemometer, resulting in erroneous wind data. If weather station is located under a tree or an overhang, the rainfall data measured by the station will not be correct. The location weather station is the most important part of installation.
