Paso 5: El código
El bucle void comprueba las sondas cada 60 minutos y si la tierra está seca inicia la función waterOn que encienda la bomba hasta alcanzar el alto nivel de humedad o pasados 5 segundos.
Si nivel húmedo llega a la bomba se apaga y vuelve al bucle vacío, si 5 segundos pasados y el nivel no lo alcanzaron luego se apaga la bomba y abrir y cerrar error (función pumpErr) hasta cercanías de nivel húmedo (riego manual)
