Team Vision for Integrated System Build & Test Phase
|Test the motion and pressure sensors together inside the simulated pit based on S25 and S26 test plan.|
|Have a mock up for the pressure and motion sensor data to allow creation of the macro in phase 3.|
|Once testing on the mock pit has started, make any final adjustment for ease of testing.|
|Demonstrate placement pressure sensor inside Arborloo.|
|Work on waterproofing and reducing the size of the box.|
|Calculate and test the power consumption of the removed chip in mAh.|
|Calculate the power consumption for each individual sensor.|
|Determine the battery configuration necessary to run the system for 45 days.|
|Find and implement power saving code to reduce power even more.|
|Complete testing of the pressure and motion sensors based on all of the use cases in the simulated pit.|
|Determine the rate of false positives for each use case.|
|Have battery system fully functional and able to last 45 days based on hand calculations and testing.|
|Test temperature and soil moisture sensors to ensure they are fully functional.|
|Finish Excel Macro to display data easily.|
|Finish machining and mounting box based on phase 5 testing.|
|Purchase and implement waterproofing techniques to ensure the box is waterproof.|
|Finish testing of preferred pH sensor and determine a technique for the most accurate readings.|
|Purchase cups and rods for the pH sensor.|
|Fabricate/solder board if necessary.|
|Finalize budget for producing 100 systems, so Sarah can submit her grant.|
Our System Stayed Above 3.3V for 12.5 days.

- Green = Engineering Requirement fulfilled by testing.
- Yellow = Engineering Requirement is projected to be fulfilled, but testing is not complete.
- Red = Engineering Requirement will not be satisfied.
Note: Requirement S20 is red due to misunderstanding about its meaning. The requirement will be modified after a discussion with the customer so that it can be fulfilled.
