I am playing around with the VEML7700 to get the ambient light.
I have done 4 readings and consistently I get two different values.
Here are my settings and values:
Gain 1, IT 100ms -> 7351 counts * 0.0576 = 423 lx
Gain 2, IT 100ms -> 14706 counts * 0.0288 = 423 lx
Gain 1/4, IT 100ms -> 2249 counts * 0.2304 = 518 lx
Gain 1/8, IT 100ms -> 1123 counts * 0.4608 = 517 lx
Gain 1/8, IT 25ms -> 280 counts * 1.8432 = 516 lx
So I get basicly two different results, 423 lx and ~517 lx. The difference gets bigger the brighter the light. But allways the first two are the same and the last tree are the same.
What is going on here? any one have some tips?
