Abstract:
More and more, small and medium producers have increased the demand for growing
vegetables, as it is an alternative of consistent extra income due to the sharp increase in demand
for products grown mostly in ecological production. Among the production models,
hydroponics stands out, which is very versatile with respect to installation and handling,
presenting several advantages, such as the need for no soil preparation and the possibility of
installing it in small or unusable environments for other types of crops. For medium and large
commercial applications, there are some special cares regarding calculations, which define
parameters such as pump power, greenhouse dimensions, among others. In this sense, the
present study aims to develop a remote monitoring and control system, via mobile application,
for hydroponic cultivation of vegetables through an Arduino microcontroller and Esp. For this
purpose we started from the problematic of hydroponic cultivation and its current difficulties
inherent to its form of development, suggesting automation methods based on monitoring and
control that aim to mitigate or, in some cases, completely extinguish the dependence on manual
work and constant monitoring by the producer. The results showed that the cultivation of
hydroponic lettuce with the use of the application under the conditions studied, presented an
excellent potential of viability, constituting an alternative for producers interested in the use of
the system developed. However, it is necessary to emphasize the need for guidance from
qualified technicians in order to obtain success in hydroponic cultivation and that this project
requires investments, in the amount of approximately R$ 1,600, in relation to the total value of
a hydroponics represents 10 to 15% of the value, which is relatively low. It is concluded that
the implementation of the monitoring and control system for hydroponic cultivation is feasible,
and allows a return in the medium term, what makes this possible is the more accurate and real-
time monitoring of production and optimization of the use of inputs.
