2.1 Block Diagram

The block diagram provides a visual representation of the system's architecture, illustrating the interconnections between the evaluation board and the various modules. It depicts the flow of data and control signals from the sensors detecting physical changes in the environment to the D4i gears responding to commands. The LTE module's connection to the remote server is also highlighted, showcasing the pathway for remote control and monitoring. This diagram serves as a roadmap for understanding the system's operational dynamics and the interaction between its components.
