The wind speed and direction sensor of the wind turbine can measure the wind energy at different heights of the wind measuring tower, and is used for all-weather monitoring of wind speed, wind direction, temperature, humidity, atmospheric pressure, solar radiation, rainfall and other element values. The built-in large capacity data memory will communicate with the central computer through wired, data transmission radio, GPRS mobile communication and other methods, and transmit the wind energy data to the central computer database for statistical analysis and processing. It is an indispensable part of wind power generation.
