Weather station - Data Logger

          In this article, you can see how to make Weather station device - Data Logger for measuring and storing measured values.

          It can measure atmospheric parameters like:

               - Wind speed [m/s] - [km/h],
               - Atmospheric Pressure [mBar],
               - Temperature [℃] - [℉],
               - Humidity [%],
               - Light intensity [lux],
               - LPG detection [%] and
               - Altitude [m].

          Weather station - Data Logger can be used in Botanical Garden, Libraries, Hospitals, Mines, etc, not only in Agriculture.

          All values of measured parameters can be stored on few medium like:
     
              - SD (Security Digital) card,
              - SMS (Short Message Service),
              - IoT cloud ThingSpeak

          Block diagram of Weather station is below:

          Electrical scheme of Weather station is posted below:

          When Weather station - Data Logger is start-up, first you need to set Language of device, it can be:
               - English,
               - Serbian,
               - Deutsch and
               - French.

         After that, you have to set actual time and time when weather station to stop the measuring.
       
         Next is settings of the Name of file if you storing measured values on SD card, reason of that is you doesn't need to delete previous measurement.
       
         When you storing measured values on SD card, and you are not near the device, and you need to know when pick up the device at the end of measuring. In that case, you need to set number of cell phone where you can receive SMS like notification of end of measuring.

          After that settings, on LCD display you get message of starting measuring and storing on SD card.

          When measuring is done, GSM SIM800l module send SMS on number you set before.

          Realized Weather station - Data Logger on protoboard is on this picture:
