Abstract
The request at hand offers a complete designed engineering–optical-electronic-chemical system for the absorbance measurements of colored solution or measurement of the amount of turbidity for a solution that might contain or have already formed a precipitate or a suspensoid; via the irradiation with white snow Light Emitting Diode(LED); which contain all the main colors of the visible spectrum which are the blue ,green and the red.
Following as a result all together give a unique mode in irradiation the precipitate as shown in the attached figures or even for the colored solution for a well known standard reaction known all over the world.All the mentioned reactions were regarded as a means to test the capability of the presented offer especially in using a solar cells as a detector for collecting the light which is characterized by high output voltage with no amplification is required or any electronic circuit complexasion.
