The series is a series of electronic digital anemometer to measure wind speed that is widely used in the field of Meteorology and Geophysics Agency or weather station. The name of this tool comes from the Greek word Anemos, which means wind. The first designers of this tool is Leon Battista Alberti in 1450. In addition to measuring wind speed, the tool also can measure the magnitude of the wind pressure.
As we know, wind is air that moves from one place to another. The wind blows because some parts of the world gets more sun than anywhere else. Land surface air temperature in the heat makes it rise. As a result, the air expands and becomes lighter. Because it is lighter than the surrounding air, the air will rise. Once the heat was rising, its place was soon replaced by the surrounding air, especially from the air above the cooler and heavier. This process occurs continuously, as a result we can feel the movement of air or what we call wind.
Anemometer is designed to measure and record wind speed distribution of 0-17 meters per second +. It was designed for high reliability, ease of construction, and for a wide range of environments. Data logged for 30.46 days (1/12 of one year), and then stored for 11 months. Data can be retrieved with a laptop computer at any time within 12 months of logging. Windmeter is self powered by a solar panel and battery.
