               Ricevo =  Convert.ToString(provabyte);
               if ((provabyte == 13) || (provabyte == 10))
                       {
                   singolocarattere = Ricevo;
                   if  (singolocarattere.Contains("TempInterna:" ))
                           {
                       TemperaturaInterna = singolocarattere.Substring(13);
                       Ricevo = "";
                   }
                   if (singolocarattere.Contains("TempEsterna:"))
                   {
                       TemperaturaEsterna = singolocarattere.Substring(13);
                       Ricevo = "";
                   }
                   if (singolocarattere.Contains("TempScheda:"))
                   {
                       TemperaturaScheda = singolocarattere.Substring(13);
                       Ricevo = "";
                   }
                   if (singolocarattere.Contains("TempScheda:"))
                   {
                       TemperaturaScheda = singolocarattere.Substring(13);
                       Ricevo = "";
                   }

                   if (singolocarattere.Contains("UmiditaInterna:"))
                   {
                       TemperaturaScheda = singolocarattere.Substring(15);
                       Ricevo = "";
                   }
               }
               else
               {
                   Ricevo = Ricevo + (char)provabyte;
               }

                       {

Solution 1

If you know you are going to get both a LF and CR, then only look for one of them. Ignore the other - be sure to throw it away. Don't put it in your string.

Solution 2

serialPort1.WriteLine("Data Input String");

using WriteLine to send a string data and finish with a LF character

Solution 3

to remove the \n\r from a string use :-

...
// Read myString from Serial Port 
//
// Then Replace \r\n with Empty 
myString = myString.Replace("\r\n", string.Empty);
