Patent ID: 8474328

Claim:
A device for measuring wind speed and direction, comprising: a hollow main body including an upper part and a lower part, the upper part having an elongate neck; an electronic circuit housed within the main body, the electronic circuit including a bipolar magnet above a magnetic encoder, the bipolar magnet being attached to the axle and rotating at the same speed as the axle; an axle in communication with the electronic circuit and extending through the elongate neck; and one of a rotor and a vane tail secured to a distal portion of the elongate neck and in communication with the axle, the rotor and vane tail being interchangeable, and the magnetic encoder being programmable to selectively measure the rotational speed of the bipolar magnet when the rotor is secured to the distal portion of the elongate neck and the angle of the bipolar magnet from an initial reference position when the vane tail is secured to the distal portion of the elongate neck.
