3. Project Proposal Using a humidity, UV-c, and temperature sensor, Team Parro will plot a graph of absolute humidity vs. altitude, UV-c vs. altitude, and UV-c vs humidity, in a hope to see a spike in absolute humidity at the upper boundaries of the ozone layer due to an increase in UV-c.

7. Design The payload consist of two boxes, a UV sensor, humidity sensor, temperature sensor, balloon sat circuit board (includes EEPROM chip, and processor), an analog to digital converter, and a Lucite window. The balloon sat circuit board resides in the smaller box and connect to the sensors through the ADC. Humidity and temperature sensors will be outside of both the inner and outer box, while the UV sensor will remain inside the larger box. Hand warmers will be placed inside the larger box to keep the temperature above the electronics operating temperature.

8. Payload Construction

9. Software Our program will read our humidity sensor from CH0 of the ADC and our UV sensor form CH2 of the ADC every 13 seconds. After every read, the current address counter will be saved into address 0 of the 24lc64. Before each read, the program will check itself and shut down if there is not enough free space.

10. Testing

11. Mission Operations The software will be run and the box sealed. The sensors will then begin collecting data and will continue to do so until recover or when memory is full. The payload will then be recovered and the data collected from the EEPROM chip via a serial connection.

12. Data Acquisition and Analysis The data will be retrieved by running a program to print out the stored data onto the debug screen. The data will then be copied and pasted into excel where it will be calibrated and plotted.
