Hi Jingguo,

Yes, the optical sensing area is centered on the package.

The device response is proportional to the sensor area that is illuminated. For example, if 25% of the sensor area is blocked the device reading would be attenuated by 25%. In this example, if you shine 100 lux on the sensor we would expect the device reading to be 75 lux.

Hi Nicole,

when using OPT4001-Q1 EVM, there always exist a fault report as the follow picture, 

And the OPT4001EVM is good, do you know why? They need OPT4001-Q1 in automotive.

And could I let customer do the evaluation with OPT4001EVM in this moment?

add a clear error picture

Hi Jingguo,

To troubleshoot this GUI error I would recommend switching the USB port that is being used and restarting the GUI. Please let me know if this resolves the issue.

Best regards,
Nicole
