I have an application to detect materials under a blacklight. The attached photo shows the 2 materials that I’d like to detect automatically. Do you think Pixy could do this and return a digital output if it detects the “bluer” looking material.
Hello,
Pixy can detect the objects you train it to based on color. You could train Pixy on the blue color and it should be able to detect it. 
Hope this helps!
