The present invention discloses a guiding wind-direction and wind-speed sensor, comprising: an upper cover board, a lower baffle body, a side baffle board, a through hole, a cantilever beam array and a strain sensor; the upper cover board and the side baffle board are produced by utilizing the lithography and the corrosion technologies of the micro-electro-mechanical system (MEMS) technology; the upper cover board and the side baffle board are bonded; the patterns of the lower baffle board, the through hole, the cantilever beam array and the strain sensor are produced on a silicon wafer; the strain sensor is produced by sputtering; the through hole and the cantilever beam array are produced by the corrosion technology; and the two parts of a wind-direction guide component and a wind sensitive component are produced by bonding. The sensor is characterized in that the wind-direction and the wind-speed can be measured simultaneously, the device can be produced to be very small by utilizing the micro-electro-mechanical systems (MEMS) technology, which can be less than 10mm multiplied by 10mm multiplied by 10mm. The sensor can be widely applied in meteorological exploration, environmental monitoring, national defense, transportation and other aspects.
