    Thanks for your comment. I think sooooo, too! You are very knowledgeable.
    Digital pH meters are accurate, but sometimes that accuracy is not needed.

    OK. I shared this code. Please use it carefully!

    Thanks for your comment.
    I measured RGB for each color of pH test paper.
    I plotted the RGB values and pH values, I created three functions. (Please refer figure "RGB values and pH values".)
    The pH values of the three functions are averaged.
