Wind direction/wind speed measuring device

The present invention relates to a wind direction/wind speed measuring device comprising: an acceleration sensor; a sensor housing in which the acceleration sensor is accommodated; a support bar of which one side is connected to the sensor housing and the other side is fixed, and which supports the sensor housing such that the sensor housing moves by wind; a sensing/wind speed table on which a plurality of registered sensing values, and registered wind speed values corresponding to each registered sensing value, are recorded; and a wind direction/wind speed control unit for extracting, as a current wind speed value, the registered wind speed value corresponding to any one, which corresponds to a measured sensing value detected by the acceleration sensor, of the plurality of registered sensing values and determining a current wind direction on the basis of the measured sensing value. Therefore, the wind direction and wind speed can be measured at lower cost and with a simple structure by using the acceleration sensor.
