DesignDesign

The payload will consist of two boxes, a UV sensor, The payload will consist of two boxes, a UV sensor, humidity sensor, temperature sensor, balloon sat humidity sensor, temperature sensor, balloon sat circuit board (includes EEPROM chip, and circuit board (includes EEPROM chip, and processor), an analog to digital converter, and a processor), an analog to digital converter, and a plastic window.plastic window.

The balloon sat circuit board will reside in the The balloon sat circuit board will reside in the smaller box and connect to the sensors through smaller box and connect to the sensors through the ADC. Humidity and temperature sensors will the ADC. Humidity and temperature sensors will be outside of both the inner and outer box, while be outside of both the inner and outer box, while the UV sensor will remain inside the larger box.the UV sensor will remain inside the larger box.

Hand warmers will be placed inside the larger box Hand warmers will be placed inside the larger box to keep the temperature above the electronics to keep the temperature above the electronics operating temperatureoperating temperature

Tim will immediately begin working on Tim will immediately begin working on software development.software development.

Once parts begin to come in Josh and Sean Once parts begin to come in Josh and Sean will modify already constructed boxes to will modify already constructed boxes to fit the needs of the sensors.fit the needs of the sensors.

Jason will then work on interfacing sensors Jason will then work on interfacing sensors with the balloon sat and testing sensorswith the balloon sat and testing sensors

Mission OperationsMission Operations

The software will be run and the box The software will be run and the box sealed. The sensors will then begin sealed. The sensors will then begin collecting data and will continue to do collecting data and will continue to do so until the flight is completed; when so until the flight is completed; when the battery power or memory will run the battery power or memory will run out. The payload will then be out. The payload will then be recovered and the data collected from recovered and the data collected from the EEPROM chip via a serial the EEPROM chip via a serial connection.connection.

Data Acquisition and Data Acquisition and AnalysisAnalysisAll data from the flight will be recorded on the All data from the flight will be recorded on the

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