The invention relates to a
wind speed and direction sensor. The
wind speed and direction sensor comprises a
signal collection part, a digital power supply part and a pedestal support part; the
signal collection part is used for collecting signals of environment
wind speed,
wind direction and temperature and transmitting collected signals to the digital power supply part; the digital power supply part is used for collecting an air pressure
signal, and, in the meanwhile, the digital power supply part is used for
processing the collected signals of air pressure, environment wind speed,
wind direction and temperature and converting the collected signals to digital signals; the pedestal is used for supporting the
whole body of the wind speed and direction sensor and is used as an electric interface for communication between the wind speed and direction sensor and an external
control system. The wind speed and direction sensor firstly adopts a
measurement device constituted by double-heat-membrane sensitive bodies, realizes synchronization collection of signals of environment wind speed and
wind direction and provides more direct and accurate measurement data. In the meantime, the wind speed and direction sensor can measure signals of temperature and air pressure and can provide parameters of environment wind speed, wind direction, temperature, air pressure, etc, according to a required frequency and format.
