Sensing the quality of light
For the first assignment I decided to observe the quality of light in my environment. I am quite sensitive to the kind of light I am exposed to, and I feel like it probably affects my mood. I hate being in badly lit rooms (especially if it's overhead, fluorescent light)and always feel better when I am in the sun.
I decided to use a color sensor for my measurements. It has photodiodes covered with red, green, and blue filters to measure the color of the light. Unfortunately I didn't have enough time to make the sensor wearable, so the measurements I took were all in the same room, under different lighting conditions. I used a bluetooth Smirf to send the data to my cell phone, and then DanO's downloader application to send the data to my computer. I made a graph of my measurements in excel. I would like to go a little further with this, and try and get recordings throughout a day. If I get some time I will work on this further.
