Light



=Purpose=

The purpose of this assignment is to analyze data collected from the three light sensors attached to the DREAMS project. The data measure the energy received by three different categories of light: visible, ultraviolet, and infrared. The different amounts of energy received will be compared.

=Procedures=

Pre-Launch
Before launching, multiple steps must be taken. The light sensor must be analyzed and found to function as intended. The sensors will be run through a first test in which no filters are used; these numbers should be similar. Then, the respective filters will be placed over each sensors; these numbers must also be consistent. In doing this, errors were found. The voltage readings received using a multimeter were found to be too high for the arduino. Thus modifications were made to the sensor. The connection of pins four and five was severed and resistors were placed between pins two and five. Then, ten kiloOhm resistors were placed on the visible and ultraviolet sensors. Infrared, because it received too low of a reading, received a one hundred kiloOhm resistor. Data was then taken in an SD card and analyzed for consistency. The sensors were then mounted to the lower box.

Launch
The sensors must be tested to function as intended and to record consistent data with and without lenses. The data recorded just before launch should be consistent with the data derived in the Pre-Launch stage. Then, an blank SD card will be placed in the sensors' arduino, and it will be turned on and set to record data.

Post-Launch
The SD card will be removed from the arduino, and the data will be analyzed.
