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.
The payload consist of a HOBO which will have an IR sensor and temperature probe attached. A small digital camera will be included separate from the HOBO.
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.
HOBO + Battery 50g
Temperature Probe 10g
IR Sensor 10g
Camera + Battery 42g
I-V Converter/Amplifier 50g
Total Weight 162g
Leftover weight for box and insulation 838g
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.
HOBO- 1s/10s x 20mA(max current) x 2 sensors = 4mA, 4mA x 6 hours = 24 mA/ hr
Will require a 5V battery > 25mA/hr
Camera- 1s/180s x 25mA = .138mA, .138mA x 6 hours = .833mA/hr
Will require a AAA battery > 1mA/hr
Op Amp- 1s/10s x 20mA(max current) = 2mA, 2mA x 6 hours = 12 mA/ hr
Will require a 5V battery > 13mA/ hr
All of batteries will be lithium batteries ordered from Energizer
Items to be PurchasedEstimated CostInfrared Sensor $200
Digital Camera $40 HOBO $120
Total Estimated Cost $400
