Floral Sensor

by vbalaji on Wed Aug 14, 2019 1:32 am

I recently purchased a flora color sensor Flora Color Sensor with White Illumination LED - TCS34725 from a local shop near chennai. i works fine and gives reading in the serial monitor, but the problem is the values for the same color is different at different times.
First when i start place red color papers at the top of the sensor it gives this
Code: Select all | TOGGLE FULL SIZE
Code: Select all | TOGGLE FULL SIZE
R:22  G:12 B:12


after few minutes when i place the same color again (red color paper) now it shows
Code: Select all | TOGGLE FULL SIZE
Code: Select all | TOGGLE FULL SIZE
R:42  G:32 B:32

after few minutes when i place the same color again (red color paper) now it shows
Code: Select all | TOGGLE FULL SIZE
Code: Select all | TOGGLE FULL SIZE
R:102  G:92 B:92

the value keep on raising for the came color paper,

[list=]What should i do?
My teacher told to calibrate the sensor but i cant find how to do calibation?
Should i change the sensor?[/list]

It may be how you are holding the paper over the sensor and changes in other lighting in the environment.

What if you just leave the paper on the sensor and watch the values. What do they do over time?

We should see if we can reproduce this behavior. Can you post a photo of your setup and show the paper being used, etc. We'll try it here also.
