The prototyping phase is a crucial step in our development process, where we translate the theoretical design into a tangible form. We apply the elaborated design on the PCB and the selected components, testing all the knowledge acquired up to this point. During this phase, the true nature of our IoT sensor emerges and the operational challenges are addressed and solved.

We start with the practical application of the design on the PCB, following the outlined structure with precision. The careful choice of components is fundamental, and each element is carefully positioned to ensure optimal operation.

This phase involves the creation of the first prototypes, and we are aware that several problems will emerge during testing. Iteration becomes essential, and prototyping a series of successive versions allows us to constantly refine and improve the characteristics of the sensor. The tests are thorough, involving real simulations of the expected operating conditions.

A distinctive element in this phase is the scientific approach thanks to the in-depth knowledge in Chemistry and Industrial Chemistry. This approach allows us to study the data collected by the sensors in a scientific manner from the early stages of prototyping. The raw data coming from the pretests of the sensors are carefully rearranged and interpreted, anticipating future needs for continuous interpretation. Scientific attention is crucial to understand the potential drift, the deterioration of the sensors or any excessive energy consumption, mitigating the risks that could emerge in the subsequent phases.

In parallel, we focus on the creation of the database that will accommodate the data coming from the sensor. The structure of the database is carefully defined, including all the tables necessary to interpret and interpolate the data. A great effort is dedicated to the hypothesis of the desired functionalities, determining how the data will be displayed, automated, notified and re-elaborated. This phase requires a clear vision of the future functionality, helping to ensure a smooth implementation in the following phases.

In conclusion, the prototyping phase is a period of intense practical activity and testing, where the sensor takes shape and its functionality is progressively optimized. Our scientific approach and dedication to quality are crucial to the success of this phase and to ensure the robustness of our IoT sensor.
