«SOKOL-M1» automatic meteorological stations in default configuration do not have
special measuring instruments, test and other equipment, tools and accessories, which are necessary for
control, regulation (adjustment), maintenance and current repair of the product and its components.

Measured parameters are transmitted by the weather station to the server with the set
periodicity: from 10 to 59 minutes. The decoding of the information package transmitted to the server is
given in Table 4.
