Hello!
I'm trying to measure light colour temperature and intensity to display it in a LED, so I was looking at the TCS34725 sensor which seems able to do this. I've noticed it includes a white LED, so I was wondering if it's going to mess up the measurements or not. If so, is there a way I can turn it off?
Thank you!
This uses the white LED to light up the subject with a known colour of light, You could remove it or the LED that controls it current.
*I have assumed you are using an Adafruit or similar board
If you are considering the Adafruit TCS34725 module, the schematic shows an input connection "LED_EN" to control the white LED.
The LED is on by default. Set the input connection LOW to turn the LED off.
If you are serious about making a color temperature measurement, you would want to calibrate the sensor, by comparing its output to that of a professional instrument, or use one or more calibrated light sources.
Thank you very much! Will a light meter like the ones used for photography work as comparison?
That would depend on whether the light meter measures color temperature.
