Wind speed is an important factor meteorological forecast

accurate forecasting of wind speed

has certain influence on people’s production and living. Two-dimensional ultrasonic wind speed sensor is one of the most important way of wind speed measurement in meteorology and industry

on the basis of traditional ultrasonic wave anemometer

accurately adjust by measuring temperature and humidity of air

compensate influence of environmental factors such as rain and fog

design a 200 k Hz ultrasonic anemometer all-weather based on STM32 processor

it is proved through experiment that the device can realize accurate wind speed and wind direction measurement

all-weather measurement error is small.
