 		 #143684 - About analog color sensor
Responding to: ???'s previous message
Hello Stefan,
Thanks for your precious time.

Currently my outputs of each sensor are tied to timer1,timer2,timer3 of AT89S52.
The output rise time for Digital sensor(I2C) 240usec

It has 10 bit resolution.

But I am not sure whether it will differentiate between the smallest change in color.

The analog sensor you are mentioning,in their datasheet I found that applications include enviromental lighting & general color detection.

So I am worried if it will be suitable for my reflective color sensing application where color variation between objects is very small
