Wind speed and direction detection device

The utility model discloses a wind speed and direction detection device, especially relates to a wind speed and direction detection device based on piezoelectric effect. The device comprises an induction system and a measuring system. The induction system comprises a vertical rod made of a rubber material, piezoelectric ceramic pieces, a rotation device, and a wind reception device. The number of the piezoelectric ceramic pieces is 16, and the piezoelectric ceramic pieces are symmetrically and uniformly adhered to the outer wall between the top end and the bottom end of the rubber vertical rod on a same horizontal height. The rotation device is on the top end of the rubber vertical rod. The wind reception device is connected with the rotation device through a nylon rope. Two ends of the piezoelectric ceramic piece are connected with the measuring system. The device is installed on the top of a building, so the wind reception device swings with wind, and drives the piezoelectric ceramic pieces on the vertical rod to generate output voltage, and the output voltage is input to a display circuit to display. The device can measure wind directions and wind speed at the same time, and has relatively high precision.
