The weather station is capable of measuring and transmitting all key indicators necessary for the efficient operation of specialized services to the central computer:

• temperature and air humidity
• direction, wind speed and gusting
• atmosphere pressure
• dew point temperature
• type and intensity of precipitation
• road surface temperature
• road temperature at depth
• amount of precipitation on the road surface
• presence of the reagents on the road surface

The basic meteorological station consists of the following components:

• Station controller
• Air temperature and humidity sensor
• Precipitation sensor
• Wind direction and speed sensor
• Ground surface temperature sensor
• Surface condition sensor
• Atmospheric pressure sensor
