PURPOSE: A device for confirming a wind direction and a wind speed of an aerogenerator is provided to accurately measure the wind direction and the wind speed regardless of the operation of a rotor blade. CONSTITUTION: A device for confirming a wind direction and a wind speed of an aerogenerator comprises a projected body(10), a central pressure sensor(20), a side pressure sensor(30), and a control unit(40). The projected body is projected frontward in a rotation central shaft or a rotor hub(9). The central pressure sensor is installed in the front side of the projected body. Two or more even numbers of the side pressure sensors are installed in a side of the projected body. The control unit calculates the wind direction and the wind speed by receiving pressure measuring signals of the central pressure sensor and the side pressure sensor.
