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. |

- 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.
