RGB sensor for detect changes in skin color of fruits

Abstract

In this work an optical sensing setup is designed and implemented to estimate the ripening in fruits. Here by white light reflected signal the color fruit can be calculated to provide information about the fruit condition. The main components in the proposed system are red, green and blue (RGB) module, photodetector and an optical plastic fiber. Moreover the sensing system is compact and versatile, due to the light signal used in the system can me adequate according to some fruit requirements by using a Labview interface, besides the detection and result displaying is proposed by a microcontroller device and Matlab interface. In order to demonstrated the system proposed a guava fruit was used to show the evolution color changes during its ripeness.
