  2. Mission Overview • This project is designed to detect the levels of methane, CO, and UV light that exist at high altitude. • The possibilities of methane or CO levels becoming dangerous to human life as altitude increases will be analyzed • The effects of exposure to different atmospheric conditions • Expect higher levels at higher altitude

  3. Mission Objectives • The BalloonSat is not to exceed 850 grams. • The BalloonSat will cost no more than $100. • The internal temperature of the BalloonSat shall remain above -10 degrees Celsius. • The BalloonSat shall carry a digital camera to record the satellite’s surroundings. • The BalloonSat shall carry six UV photodiodes, one methane gas sensor, and one carbon monoxide gas sensor to assess high altitude atmospheric conditions.

  4. Objective Requirements • The BalloonSat will be constructed with light weight, durable foam core • The BalloonSat will be cubic in order to not use unnecessary foam core and to ensure that heat easily reaches all components. • No structural testing shall be done with sensors inside. • The heater shall be powered by its own batteries. • The heater shall be put on its own switch. • The camera shall be positioned so that there are no other satellites to disrupt the image. • The gas sensors shall be embedded on top of satellite to avoid unnecessary wind resistance • One UV photodiode shall be on every face of the structure to ensure constant data.

  5. System Requirements • Heater must be tested prior to launch to ensure that it is working properly and keeping temperature above -10 degrees Celsius. • Camera must be programmed to take images every 10 seconds and store them on the memory card. • UV photodiodes shall be encased in tubing to provide additional strength. • The methane gas sensor must be calibrated to set off an alarm once it detects 50,000ppm -150,000ppm prior to launch. • The carbon monoxide sensor must be calibrated to set off an alarm once it detects 50ppm prior to launch.

  6. Design • 6 UV photodiodes on each face • 1 Methane gas sensor on top • 1 Carbon monoxide sensor on top • Parts • Ordered/Obtained • Foam Core, AVR microcontroller, Digital Controller, Resistor Heater, HOBO, Insulation, CO sensor/module, CH4 sensor/module, UV photodiodes, American Flag • To be ordered • Tubing, wires • UV photodiodes in tubes • Gas sensors embedded in foam core

  7. Budget

  8. Testing • Experiment Testing (October 11) • Black light, butane hair curler, propane • Camera Testing (October 15) • Functional Testing (October 17) • Drop, Kick, Whip • Mission Testing (October 24) • Systems

  9. Expected Results • More UV radiation at higher altitudes • UVA • Dangerous levels of methane gas • 50,000ppm – 150,000ppm • Dangerous levels of carbon monoxide • 50ppm

  10. Organization

  11. Worries • Time Management • schedules • Testing of sensors • Black light (exact UV emission) • Calibration • High enough level • Alarm recording
