摘要
A wind direction meter has the following plurality of sensors and a control unit. Each sensor has a first surface and has first and second interlayer connection members made of different metals or semiconductors. Further, the wind direction meter includes a thermoelectric conversion element which generates an electrical output when a temperature difference occurs between first ends and second ends of the respective first and second interlayer connection members. The sensor generates an electric output when the surrounding air, whose temperature has been changed by a heater, is moved by the wind to produce a temperature difference between the first ends and the second ends of the first and second interlayer connection members. The control unit calculates the direction of the wind on the basis of the difference in output. Thus, the wind direction of a weak wind can be detected with the wind direction meter.
