Team Vision for System-Level Design Phase
From our project timeline, we were going to research various power options, counter options, environmental conditions and options, and draft system options. This was all to be done before our system review.
What we did accomplish during this phase was create a functional decomposition to better show what each part of the project does. We created a morphological chart to show many options for each task our project needed to accomplish. Selection criteria was determined and we each did some preliminary benchmarking for the different sensor categories. Then we sketched some basic concept development and system architecture. Finally We created a table of risks and the project timeline for the next 3 weeks.
Engineering Requirements Mapping
The live link is available below:
- Can be accomplished in two semesters.
- Inexpensive to duplicate.
- Compatible with Arborloo design.
- Resistant to environmental conditions.
- Discrete device.
- Accurate measurements.
- Easy to build many models.
- Easy to install and uninstall.
- Easy to retrieve data.
- Uses power efficiently.
- Has easily reparable parts.
Research has shown that constantly monitoring the pH of the pit contents is unfeasible. Reasons for this include the fact that most pH sensors are not intended for direct measurements of solids such as soil, and those that are expensive, unreliable and/or need to be cleaned and stored properly between each measurement. A possible solution may be to have the field worker acquire samples each time they visit the test site, and perform the pH level measurement elsewhere. The current sensor research, included below may still be applicable to this.
