Title: Team Parro


1
Team Parro
  • Project HUSP

2
Team Members
  • Josh Hignight Project manager and software
    development
  • Jason Rollins Responsible for electrical work
    including power consumption, sensor interfacing,
    electrical design, and balloon sat testing
  • Sean Mullins Thermal design and acquisition of
    parts for thermal needs, as well as thermal
    testing
  • Tim Butler In charge of things dealing with
    constrution

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.

Payload Construction

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.
