Hello, I was wondering if anyone knows of a circuit designed to measure coulor temperature.
I came across this in my search:
Basically, my questions are:
Would three photodiodes be accurate for measuring temperature?
Would I be better off with something like the TCS230?
And does anyone know of a circuit that already does this that I could look at?
Thanks,
Spork
Hello, I was wondering if anyone knows of a circuit designed to measure coulor temperature.
I came across this in my search:
As well as a schematic for measuring all sorts of things light-related (a colorimeter) which used two TCS230 chips.In general, color temperature meters available on the market today are comprised of three silicon photodiodes filtered for red, green, and blue sensitivities appropriate for color film. These devices measure the relative amount of energy present in these three wavelength regions and determine the color temperature based on the shape of the black-body curve that best fits through these metered readings.
