Project Proposal

• Using a humidity, UV, and temperature sensor,
  Team Parro will plot a graph of humidity vs.
  altitude, UV vs. altitude, UV vs humidity, and
  attempt to determine the height of the region
  know as the ozone layer.

UV Sensor

• No specific sensor chosen
• Issues such as plastic film availability must be
  addressed
• Will the plastic affect the amount of UV that
  reaches the sensor?
• A plastic window may not be a viable option. If
  so, a UV sensor more resistant to temperature
  will need to be acquired

7
Design

• The payload will 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 plastic window.
• The balloon sat circuit board will reside 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

Basic Electrical Design
A VERY basic design of the board and sensor
interface

Payload Construction

• Once a UV sensor is agreed upon and the total
  power is checked, all parts needed will be
  ordered.
• Tim will immediately begin working on software
  development.
• Once parts begin to come in Josh and Sean will
  modify already constructed boxes to fit the needs
  of the sensors.
• Jason will then work on interfacing sensors with
  the balloon sat and testing sensors

10
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 the flight is completed
  when the battery power or memory will run out.
  The payload will then be recovered and the data
  collected from the EEPROM chip via a serial
  connection.

11
Data Acquisition and Analysis

• All data from the flight will be recorded on the
  EEPROM chip that will be located on the main
  Balloon Sat circuit board. Care has been taken
  to ensure that the EEPROM is sufficient for this
  job. Because all data is stored inside the
  payload it self, the payload will have to be
  recovered after the flight is completed. The
  data will then be taken off of the EEPROM and put
  on a computer where it will be plotted against
  altitude using MathCAD software.
