Аннотация:We present the results of the development and study of a weather station designed for astronomical observatories at the Sternberg Astronomical Institute (SAI) of Moscow State University (MSU). The weather station is equipped with sensors for measuring air temperature, humidity, pressure, wind speed and direction, sky temperature, as well as the concentration of dust and aerosol particles, and precipitation. The station has no moving parts and is designed for outdoor operation. The wind speed and direction sensors, as well as the precipitation sensor, were fully developed by the authors. Their design and research results are presented.
