Field Sensor- Color Recognition Sensor

The three primary colors of light

To my surprise the light of different colors mixed together to produce an interesting phenomenon. Most of us could know the three primary colors of light are red, green and blue. However, equal amounts of red and green light can be turned yellow, green and blue can be mixed cyan; equal amounts of red and blue light obtained is magenta, the same amount of red, green and blue light actually been white. Do amazing now!

 Color Recognition Sensor
Because of these coincidences, intelligent man produced the Color Recognition Sensor, which belongs to field sensor. This is a talk about the color of the object surface into a corresponding voltage or frequency output. Its application is very extensive. For example, the monitor's color calibration device; color printers and plotters; paints, textiles and cosmetics manufacturing; and medical applications, such as blood diagnosis, urine analysis, and tooth shaping.

Cautions
Color recognition is to avoid the interference of external light.
Light emitted from the light source to try to focus .
The first is the need for the use of white balance adjustment.
