Re: [DIYbio] Re: Does Anyone Know Of A Submersible Arduino/RaspberryPI Compatible Spectrometer?

Also. Is it going to need to be cleaned?

Hey there!

Not sure if this has to do with oceans, but remember it has a lot of virus based biological materials in it. It could mean low amounts phosphorus.

What sort of power restrictions are you working with? Solar, wall socket, or something else?

Check out https://www.adafruit.com/product/1918 for a UV sensor in the 240-370nm so would work for the 280 nm protein absorbance peak. You will also need a 280 nm emitting LED, these are about US$30-40 on ebay.

Hey! I'm also looking for a UV spectrometer to detect the presence of proteins. Are there any cheap alternatives??

The subject pretty much says it - I'm trying to find a (hopefully cheap - under $200) Arduino or RaspberryPI compatible photospectrometer which can be submerged for long periods of time in water to log water quality.  I've been searching around a bit and can't find any, but if someone knows of one which could be hacked fairly easily (sticking it in a new case for instance) that would be great too.  I'm not too worried about calibration (I can calibrate the thing and write the code needed to identify different ions from a bunch of data,) just want to avoid having to designed the thing from a capillary tube up though light sources and sensor if at all possible.
