RGB Color Sensor

by kameronberget on Mon Jul 17, 2017 10:03 am

Hello!

I am looking at using this color sensor (https://www.adafruit.com/product/1334) to detect color in a 120" projection screen. The ultimate goal is to control an LED light strip based on the dominant color in the screen. My question is...Will this sensor be able to detect color from 20' away while pointed at the screen?

Yes, but you may need to add some masking and.or optics to control the field of view. Like all planar light sensors, the response pattern for this one is Lambertian: The sensitivity is proportional to the cosine of the angle from the central axis.
