Si1133 - test code with and without diffuser

Hi at all,

I'm working with the Si1133 sensor, using my host with an interface code read by the Optical Sensors Programmer's Toolkit Launcher Version 3.5. I have two sensors, one with a diffuser and one without it; in the same ambient these sensors give me data too different in terms of light value and I don't understand why. I use a 24 bit configuration with all  parameters (configuration, conversion, ecc) copyied from the code read by the toolkit. Could anyone tell me what's wrong ?

Regards

Hi,

 

Are you taking UV measurements or ambient light measurements? The diffuser is recommended for UV measurements but will block a significant amount of ambient light. Please use the one without the diffuser for ambient light measurement.

Ah...ok; I tried to measure ambient light. Thanks for your answer.
