You want to send data to computer processing or print them for user to read? Functions write send raw data. To print the data to Serial monitor print and println functions are used.

There are two write functions. First sends one byte. Second sends array of bytes. There is no write function to send array of ints. You could cast the array of ints to array of bytes to send the array as raw bytes for processing on the receiving side. But then you first should perhaps send to the receiving side some control data about the data package.

  Serial.write((byte*) datos, sizeof(datos));

If you want to print numbers to Serial Monitor, the print functions have variants which take a number and convert it to string. But there is no print function to print an array of numbers. You must print them one by one in a for loop. And put some separator between them (coma, space, new line).
