February 27, 2003
Science Objective
Our goal is to learn if IR radiation is
dependent on temperature or altitude in the
upper atmosphere. We are also going to
study temperature as a function of altitude
during ascent.
Payload Design
The payload will be constructed out of a BASIC
Stamp and be connected to an infrared sensor and
a thermistor. The sensors will be interfaced to the
BASIC Stamp through an ADC channel. A timing
chip will also be included to coordinate the data
with GPS data taken by the balloon systems. There
will be a camera facing the side of the box that
will take pictures at certain intervals.
Fabrication and Testing
The first step will be to design the circuitry for the
sensors and chips. While waiting for the parts to
be delivered over the next several weeks, we will
finish mounting all the basic components of the
circuit. When the ADC, RTC, and sensors arrive,
we will begin testing with an oscilloscope before
we mount the chips. The final test will to suspend
the payload above a surface and determine if the
readings taken match the actual data.

– RTC
• Attach power source
• Send command to begin transmitting time
• Use Basic Stamp to interpret signal
Mission Operations
The payload will be launched and tracked
from the ground. Upon recovery the
EEPROM will be downloaded and the data
converted to temperatures and light
intensities to determine if a correlation
exists between the two.

Data Analysis
Temperature and IR light intensity will be
measured every ten seconds during the
flight. All data will be stored on board and
recovered with the payload. Software needs
to be developed to convert voltages from
the sensors to temperature and IR light
intensity.
