@Aphototaker: thanks for the PDF, which pretty much answers my question about linearity. According to their graph (which I assume can be trusted for accuracy), these devices are very linear. And yes, I meant with respect to illumination, not wavelength, which is a whole 'nother can of worms. I'm actually thinking of using this information, plus what I'm learning in my current study of electronics, to try to build a better dusk/dawn light control than the ones available commercially (at home-improvement stores), which have no sensitivity control. I'm a handyman and end up installing lots of these for my customers, and many times they don't work properly because they're made for a certain level of illumination (daylight) which may or may not actually be present, like if it's installed in a dark corner under an eave. So it's good information to have. |
