Colour sensing arduino

Projects General Guidance

Hi,

I am new to electronics and coding but using an Arduino for my major project in my final year of product design at university. I was wondering if anybody could offer some suggestions.

I need to make a system that can read colour intensities. It is a blood protein test reader using testing strips that's colour gets more intense the more protein present. Therefore, I have started to explore Arduino colour detection. Firstly, what is the method to get the msot sensitive readings. And how can I make a system where the strip can be inserted into a device for the reading?

Thanks in advance!!

Please do not cross-post; it wastes peoples time. Your topics have been merged.

Sorry! I wasn't sure which category to put it in

Quantitative, multiband light sensors:

or for visible light only

And how can I make a system where the strip can be inserted into a device for the reading?

That is product design, not an Arduino problem.

The obvious first step is to find a sensor that can detect and measure the quantities of interest.

Well there is also the TCS230 or TCS3200 sensor that you could experiment with. As for sensitivity, the datasheet should contain some useful information.

Regarding a device to insert it into, isn't this where your new found product design skills are supposed to come in? :thinking:

I meant is there a part that means it can be inserted into the circuit

Please post a link to the data sheet for the test strips you will be using.

Have you done any research at all, that is, studied any of the material in the links you have been looking at?

The link is to a microtiter plate, not "test strips". From the data sheet:

A microtiter plate reader with a bandwidth of 10nm or less and an optical density range of 0-2 OD or greater at 450nm wavelength is acceptable for use in absorbance measurement.
