Question of Si1132 ---- VIS Light Data & UV Index Measurement

how to calculate the mixed VIS with visuable and IR light?

 

When I changed the VIS measure ment setting from under sunlight to in the room, the UV output also changed, which output of UV is right, whether need I have some calculation? Thank you!

Hi Mike,

 

The VIS_RANGE and IR_RANGE bits need to be set for a UV measurement. Please refer to the example code in the Programmer's Toolkit for how to calibrate and extract the UV Index information.
