48. Conclusions
The final results proved that is possible to develop and implement an economic
and functional solution to monitor an agriculture field at distance,
but still not yet fully reliable.
The solution proposed could help professionals of the agriculture area
to have greater control over their productions without the necessity of
their physical presence.
However, the use of the Waspmote kits are not yet recommended due to
irregularity and inconstancy of the board's performances.
