Where can I find a standalone light sensor that updates the brightness of my screen to match the ambient light level in realtime for Windows 7? My monitor does not have a sensor. I had the idea there was such a thing, but all I can find is for laptops or Macs.

There’s plenty of them on eBay, but most of them are for Apple laptops (though they can likely be adapted for general use). – Synetech Feb 10 '12 at 5:33
Any idea how I could adapt one? – jnm2 Feb 10 '12 at 12:17
Nope. I don’t have one of the sensors. The problem is that new-fangled peripherals like ambient-light-sensors and other fancy toys that new versions of Windows support (like multi-touch screens on desktops) just aren’t that common yet, so you’ll really have to put time, money, and effort into find something that works. :-( – Synetech Feb 11 '12 at 3:26

Check this before buying somethings, May be it's a solution if there's no such sensors built-in your PC...

Cool idea, it does work, but I'd rather have it update the brightness more smoothly and not flash the recording light on my webcam. Just me. – jnm2 Feb 10 '12 at 11:39
