How can I measure the power of the diffuse reflected light with a photodiode array sensor? Which photodiode array should I use? How should the experimental setup be set up? How can I read the measurement data from the array sensor? which Arduino would be helpful?
Compare the results to a known value or a value measured by a trusted device.
Experiment.
Data, sound, graphs.
The one you know.
I moved your topic to an appropriate forum category @ask178.
In the future, please take some time to pick the forum category that best suits the subject of your topic. There is an "About the _____ category" topic at the top of each category that explains its purpose.
This is an important part of responsible forum usage, as explained in the "How to get the best out of this forum" guide. The guide contains a lot of other useful information. Please read it.
Thanks in advance for your cooperation.
Pick one, and start by studying the data sheet. TAOS makes several.
As mentioned, for accurate final calibration, compare sensor readings to those from a calibrated commercial instrument.
Yes, that is just one of the many questions, addressed in your other post, that you seem totally unprepared to solve.
