I bought the sparkfun ISL29125 RGB light sensor for my senior project. According to my experiment, I tried to measure the light intensity of blue LEDs and I found that a different distance shows the different value of light intensity. (I mean the distance between LEDs and sensor) You can see in the attachment file.
But the problem is I don’t know which distance is the exact light intensity value of Blue LED.
I already searched the answer on your datasheet also on the internet but I didn’t find it. So, my question is “What is the appropriate distance between sensor and sample for measuring light intensity from ISL29125 rgb light sensor?”
Thank you in advance for your help. I look forward to hearing from you.
