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.

UV Sensor

• Boston Electronic UV sensor JEC.01C
• Max reading at 100W/m2

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.

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.

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.
