context_page_description: An automatic weather station is an automated version of the traditional weather station, either to save human labour or to enable measurements from remote areas. An AWS will typically consist of a weather-proof enclosure containing the data logger, rechargeable battery, telemetry and the meteorological sensors with an attached solar panel or wind turbine and mounted upon a mast. The specific configuration may vary due to the purpose of the system. The system may report in near real time via the Argos System and the Global Telecommunications System, or save the data for later recovery.
  In the past, automatic weather stations were often placed where electricity and communication lines were available. Nowadays, the solar panel, wind turbine and mobile phone technology have made it possible to have wireless stations that are not connected to the electrical grid or hardline telecommunications network.
context_section_description: The data-logger is the heart of the Automatic Weather Station.
  
  In high quality weather stations, the data-logger may be designed by the supplier to be the perfect solution for a particular meteorological client.
  Indeed, usually data-loggers found in the market don't fit the requirement in terms of power consumption, inputs, communication, protection against animals (ants, rats, etc.),  humidity, salty air, sand, etc.
  
  The main functions of a data-logger are:
  Measurement: the data-logger collects the information from every sensor and archives it.
  Calculation: the data-logger processes most of the meteorological data for the users (avg, min, max...).
  Data storage: the data-logger saves all the data either on its own memory or on uSD memory card.
  Power supply: the data-logger manages the power supply of the Automatic Weather Station, using a solar panel for instance.
  Communication: the data-logger manages the communication protocols with the remote server. The different communication protocols are usually GSM, GPRS, RTC, WiFi, uSD, and RS232.
