              <div>No tengo un Butia para probar pero estaria bueno
                tambien probar de hacerle una segunda alimentacion USB
                que solo tome corriente exclusiva para los sensores de
                consumo mayor.<br>
              </div>
              <br>
              Otra opcion menos viable (me parece) seria un diodo 1N4001
              en paralelo con una resistencia de 100ohm o mas que
              alimente a un cap de 220 uF (habria que calcular un poco
              mejor) y este en paralelo con el pic.<br>
              <br>
            </div>
            Por otra parte dentro de la misma idea, directamente del USB
            se alimentarian los sensores "de mayor consumo".<br>
          </div>
          Si estos provocan una caida de tension el cap 220uF (del pic)
          queda cuasi ahislado por el diodo; la resistencia es para que
          el cap se mantenga en 5V evitando la ca&iacute;da del diodo.<br>
