【Gravity:AS7341 Review】+Bought some colored paper for testing [Copy link]

 

 

I have a small sensor board, but I can't test it without the corresponding color. So I just bought some colored paper to test it.

After taking the photo, I found that the yellow paper almost turned white, so I put a piece of white paper next to it for comparison. You can see that there is a little difference. Let's see how this module is and whether it can recognize the difference.

Below is a color by color comparison

Continue to test the next yellow color, the part within the red circle in the picture. From the results, we can see that sometimes there are mistakes. I think the color distinction is not very good. The data is below, you can comment.

By the way, for this Leonardo board, I don't know if the driver is not installed properly or what, either I can't download the program or I can't communicate. After re-plugging and plugging, I can communicate again. Continue testing.

Continue testing, the phone camera is not very good, there is color difference,

The red value is identified as F7, which is actually yellow. Am I color blind? I hope other friends can try red too. Remember to tell me and let us compare.

It may be because I have been posting continuously. When I posted the second post, the picture of the previous post was also updated. Overall, it is not as good as I expected. I guess the color I chose is not very suitable.

This experiment is very good, and the evaluation is very careful! ! ! Thumbs up!

I've invested money, and I'm itching to try it out. Haha, I should have applied for a review earlier.

I wanted to do some garbage sorting, but with this result, I don’t want to do it anymore. I don’t know if it counts as completing the task.

I don't understand it at all. I just want to find a complete and usable method to convert to RGB

The value that comes out is not the RGB value, but a group of values. The larger value is that color.

I know the 8 values of F1-F8, as well as clear and NIR. I just want to know how to convert these 8 values of F1-F8 into RGB. Is there a conversion method or formula?
