Hello, why do UVI calculate in this way ? uviuvi = raw / ((gain_arr[_gain] / 18) * (res_factor[_resolution] / res_factor[0]) * 2300) * WFAC;

According to datasheet UV Sensitivity = 2300 at Gain range = 18, Resolution = 20-bit. So UVIcalc = RAW Data / 2300 * WFAC. But for other gain and resolution it should be recalculated

I know your meaning,but the UV Sensitivity = 1400 at Gain range = 18, Resolution = 20-bit.

the datasheet version is 8-Dec-15,

@rak-ltp Thank you for this information. I've contacted LITEON and they confirmed this information. The UV Index calculation has been corrected.

ok,Thank you,May I ask which version of formula is used for calculation now

[rak-ltp]

I have seen your modification,Thank you
