The invention discloses a combined miniature three-dimensional breeze speed and breeze direction inductor, which solves the problems of high equipment cost and complex structure in the prior art. The inductor comprises three one-dimensional wind speed inductors which are arranged in the three-dimensional direction of a bracket (1) respectively, and consists of a code disc bearing sleeve body (12), a main shaft sleeve (14), a rotating shaft (15), vane spokes (16) and vanes (17), wherein the top end of the rotating shaft (15) is provided with the vane spokes (16) used for mounting air vanes; the vane spokes (16) are uniformly and radially arranged in a plane vertical to the rotating shaft (15); each vale (17) forms a 45 degrees angle with the plane formed by the vane spokes (16) along the same circumferential direction respectively; the bottom end of the rotating shaft (15) is provided with a code disc (13); and through holes (19) on a turntable of the code disc are in fit with two pairs of photosensitive transmit-receive tubes to transmit optical signals to a CPU. The combined miniature three-dimensional breeze speed and breeze direction inductor is suitable for detecting three-dimensional wind outdoors and indoors.
