Microcontroller Based Product Sorting by Using Colour Sensor

Abstract

This paper presents a microcontroller based control system that can be applied for product sorting on basis of color. In many industrial applications, there is a need of sorting. Sorting can be done by using many ways according to the dimensions, colours, weight, using machine vision (image processing), material of an object etc. For example, in Thermal Power Station, electromagnetic sorting technique is used to sort ferromagnetic materials from coal. This project consists of components such as microcontroller, conveyors, colour sensors, electronic system and motors. The objects are being sorted according to their respective colour. The main conveyor has support of two separate branches which leads towards a pair of proximity sensors. In this project, the system provides a user-friendly environment to establish an easy communication between humans and process.
