Lightlevel to Lux

Hi,

has anyone a photo-/luxmeter lying around and can give me
some realworld reference values to convert the imp lightlevel to lux?

thanks

You really can’t do that. The imp’s sensor is much more sensitive to IR light than visible, so it won’t map well at all and will be hugely inaccurate for differing light sources.

thanks Hugo, i thought so.
