The design phase is when we transform conceptual ideas into tangible solutions, defining in detail how our IoT sensor will be realized. This phase plays a key role in the development process, as we not only consider the aesthetic aspect of the product, but also hypothesize its functional and technical characteristics in an in-depth way.

During this phase, we start by identifying the specific design needs of the sensor. This includes the definition of the sensors, the choice of the macro electronic components that impact the shape, and the creation of a functionality that integrates in a concrete way with the environment of use. Where necessary, especially in situations where it is required to modify specific flows, the design takes on a more elaborate and targeted role, ensuring that the product meets the most complex needs.
A crucial aspect of this phase is the design of the shape of the PCB (Printed Circuit Board), which constitutes the electronic brain of our sensor. We define the initial layout and positioning of the macro components on the board, ensuring an efficient and optimized organization. The subsequent design of the PCB is in fact closely linked to the overall design, as it directly affects the performance of the sensor.

The choice of materials is an in-depth process in which we evaluate several factors, including quality, durability, market availability and, of course, suitability for the required functionality. This phase requires special attention, as the selection plays a crucial role in determining the performance, robustness and durability of our IoT product.

Furthermore, the design is not limited to the physical part alone. We also start defining the user interface, if applicable, to ensure that the overall end-user experience is intuitive and satisfying. The design thus takes on a double dimension, integrating functionality with aesthetics to create a product that not only works well but is also pleasant to use; this last phase can however be addressed or continued in a phase even after the realization of the definitive hardware depending on the needs of timing and milestones defined.

In conclusion, the design phase is the crucial point in which we shape the initial vision into a concrete technological concept, laying the foundations for the subsequent phases of design and prototyping.
