PURPOSE: A wind vane is provided to minimize the influence of snow or rain and to be used regardless of season. CONSTITUTION: A wind vane (100) comprises a casing (10), a column (20), a film (40), a sensor set (50), and a calculation device. The casing forms a cylindrical hole on the upper end and forms an internal space in inside. The column is fixed to the floor of the internal space of the casing and is extended to outside through the cylindrical hole. The wind film is fixed to an end of the column and induces the deformation of the column by wind. The sensor set is installed on an edge part of a first end of the column. The calculation device computes the direction and size of the wind by a unit sensor. |
