Team Vision for System-Level Design Phase

The main objective in this phase of our project is to design the structure of our system. We plan to decide on a layout both mechanically and electrically while also beginning the decision making process for some components such as water pumps, pipes, micro-controllers, and sensors. In addition, we plan to perform basic cost-benefit analysis when considering some of the preliminary components we know that we will use. We plan to begin to collect materials for a small scale prototype of the system as well that we will use to test our monitoring system sensors as well as discover any unseen issues with the architecture of the system as well.
