Problem Definition Long- term goal:

● Design an integrated sensor device using a microprocessor to sense environment conditions without supplemental power and size constraint

2018- 2019 academic year goal:

● Design an integrated sensor device using a microprocessor to sense environment conditions.

Problem Statement:

● Design, build, and test a fully integrated sensing device, report and presall results to the Sandia mentors. The device is required to sense the environments in the SANDIA team's summary document.

Conclusion

uccessfully design a final solution.

CB design hindered us from utilizing the mems ccelerometer.

alidation of data are going to be confirmed/denied by echanical engineering students.

earned the importance of time management, task elegation, and risk management.
