Based on all that has been presented in this thesis it is necessary to evaluate the fulfillment of requirements and objectives described in thesis.
One of the first requirements to be fulfilled was related to the creation of a low energy consumption system. For this, we opted for the choice of BLE technology. Based on the specifications of my system, this technology proved to be the one with the best performance for the theme of this thesis, the creation of a system of wireless sensors, of low power and low cost. In addition to the performance, the choice of this technology is also reflected in the maximum range requirement of 54 meters, in this case, the BLE technology has a maximum range of 100 meters.
With the choice of technology is possible to define the network structure. In order to fulfill the requirement of creating an easy installation and maintenance system is proposed a network structure with three layers, (1) Sensing Layer, (2) Gathering Layer and (3) Cloud Layer, that communicate with each other with specific communication protocols. This conjuncture is more detailed in section 4.1 and section 4.2 of my thesis, where it is revealed that in fact the system is easy to install, since the sensing device consists of a mobile system, powered by a battery, the gathering device consists of a simple board powered by a photovoltaic panel and installed on top of a greenhouse and the Cloud device consists of a smartphone with BLE interface.
That said, in relation to the last requirement, at a minimum, there must be two measurements per zone, i.e., at a minimum two sensing devices must communicate with a Gathering device. Unfortunately, due to reasons of time, was not possible to perform the test with multiple sensing devices to a single Gathering device. However, the communication between a sensing device and a Gathering device was proved as proposed in section 3.3 of my thesis.
In conclusion, the developed prototype system complies with many of the requirements imposed at the beginning of this thesis, but also proves the concept that it is possible to implement a network with mesh typology based on the use of BLE technology.
