  1. Team Big Green SpaceGasmPre-Critical Design Review Hillary Beltran, Edward Crawford, Nicole Harris, Edward Lowe, Emily Proano, and Kevin Wong 05 October 2010

  2. Mission Overview • Mission objective: Take measurements of the concentrations of carbon monoxide, carbon dioxide, and methane gases • Expectations: Stagnant to slightly increased levels of each gas • Hypothesis: Concentrations have increased during the course of the year • Not enough time to see effects of transition • Effects of Fourmile Canyon, Loveland, and Grand County fires

  3. Mission Overview • Purpose of Mission: The team’s interest in the quality of air and changes that were recently experienced over the past few years • World’s recent transition to more environmentally sustainable resources and fuels • Recent forest fires in Colorado • Document any measured changes • Data retrieved from this flight will provide standard

  4. Requirements Flow Down: Level 0

  5. Requirements Flow Down: Level 1

  6. Design Overview: How we will Complete our Mission • Basic Circuit Structure & Implementation of Sensors • CH4, CO, CO2 • Calibration • Writing Arduino Based IDE Software (Java) • Testing of hardware and software (together) • Analyzing Data • Functions (ppm vs. altitude) • Colorado Department of Public Health and Environment

  7. Design Overview: Equipment • Equipment overview: • Provided: • Foam core, digital camera, HOBO and external temperature probe, resistors, non-metal flight tube • Purchased: • Arduino microcontroller, carbon monoxide sensors, carbon dioxide sensors, methane sensors, microSD card, breakout board, prototype board • Additional hardware will require approximately three days to arrive • Not purchased: • Dry ice, additional batteries, desiccants • These can be purchased at a local store and can be purchased within a day

  8. Design Overview: Illustrations

  9. Design Overview: Illustrations

  10. Design: Functional Block Diagram

  11. Design: Mass and Monetary Budget

  12. Design Overview: Schedule

  13. Design Overview: Proposal Requirements • Must be able to measure concentrations of carbon monoxide, carbon dioxide, and methane gases • Retrieve and store data on external memory source • Take and store images

  14. Design Overview: Proposal Requirements • Using three individual sensors that independently measure the three prescribed gases • Store retrieved data on microSD card • Embedded by insulation and heated by heater system, since directly exposed to atmosphere • Images will be taken by the provided digital camera • Images will be stored on the camera’s microSD card • HOBO • Store data recorded by external temperature cable

  15. Test Plans: Plans to Test Payload • Two major aspects to testing: • Structural tests • Hardware tests • Individual subsystem tests • Integration of entire system • Repeat tests performed for subsystem tests to ensure full system functionality and integration

  16. Test Plans: Test Already Performed • First test will be performed on Wednesday, October 6 • Drop, roll, and kick test for preliminary model of stucture • Future tests and testing schedule will be discussed later

  17. Test Plans: Tests to be Performed • Structures Subsystem: • Drop, roll, and kick tests • Cooler test • Software Subsystem: • Test individual sensors • Interface sensors together and test using the 1-2-3 method • Test functionality with mission simulation test • Communications and Power Subsystems: • Interface power sources with HOBO, AVR, and heater • Test to see data retrieved is properly stored on microSD card • Entire system: • Repeat tests mentioned above

  18. Test Plans: Schedule • In reference with the schedule shown earlier: • October 4: Begin programming the microcontroller on the integrated development environment (IDE); code, interface, and test CO sensor; begin communications tests; begin power tests • October 6: Drop, roll, and kick tests • October 10: Cooler test • October 11: Code, interface, and test CO2 sensor; continue communications tests • October 18: Code, interface, and test CH4 sensor; continue communications tests • October 22: Integration of entire system and repeat tests • October 25: Final testing completed; final satellite constructed

  19. Expected Results • Carbon monoxide, carbon dioxide, and methane gas levels are within the normal range (good air quality and healthy) • Rise in levels of gases since Fourmile Canyon, Loveland, and Grand County fires • During mission flight, cut off of data after about sixteen kilometers
