This paper presents the design and the implementation of a real-time color
based sorting system that is intended to be used in agriculture applications.
The control part of the system is realized with the versatile microcontroller
Atmega328. The color detection of the analyzed objects is obtained with the
specialized digital sensor TCS230 that contain all the circuitry that is necessary
for converting the light into frequency signal for convenient acquiring and
processing with the microcontroller. The actuation elements of the sorting
system are realized with a set of TowerPro SG90 servomotors which have a
very lightweight construction but are capable to generate relatively high
output power. Being a microcontroller-based system that relies on an advanced
color sensor and dedicated proprietary control software, the proposed sorting
system is characterized by improved reconfigurability and adaptability.
The system can be easily integrated within a very broad spectrum of
applications including Internet of Things or quality control in industrial domain.

1. INTRODUCTION

Agriculture and Horticulture is one of the largest economic sectors and it plays

the major role in economic development of India. Still in India, the traditional

inspection of fruits is performed by human experts. A lot of time is wasted in

the fields for checking the quality of the crops. In this Paper, an economic and

safe way is used to analyze the fruit or vegetable quality which is based on

colour, shape and size. Fruits should be tested via non-destructive techniques

because these are delicate materials. The most important physical property

is fruit size while colour resembles visual property. Hence, classification of fruit

is necessary in evaluating agricultural produce, meeting quality standards and

increasing market value. It is also helpful in planning, packaging, transportation

and marketing operations. If the classification and grading is done through

manual techniques, the process will be too slow and sometimes it will be error

prone. The labours classify fruits and vegetables based on colour, size, etc. if

these quality measures are mapped into automated system by using

suitable programming language then the work will be faster and error free. In

recent years, computer machine vision and image processing techniques have

been found increasingly useful in the fruit industry, especially for applications

in quality inspection and shape sorting

Colour and shape characteristics of fruits are decisive for visual inspection.
1.1 OVERVIEW

The tremendous progresses in the field of microcontrollers and sensors created

new opportunities for developing advanced solutions that can significantly

improve the efficiency of the classical systems used in various sectors of

industry and agriculture. Particularly, the agriculture domain faces nowadays a

very important technological transformation becoming more and more

influenced by the development of new concepts like Internet of things (IoT)

or self-driving machines. The benefits and the additional opportunities created

by these trends are directly related to the integration of new technologies.

The sorting process represents a repetitive and time consuming task which don’t

requires a very high level of qualification, been feasible for automation using

dedicated machines. In this context aroused the idea of implementing automates

machines for sorting objects on the basis of color characteristics. Although

seems to be easy realizable, the color-based sorting is a complex problem that

rise many issues on the design and practical implementation as well.

1.2 MOTIVATION

In most of the industries, packaging systems use a line bridge as a sorting

element in their industry. While some industriesuse manual sort in their systems

as labor is available and theyfind the sorting systems are of higher cost. But to

see, themanual sorting process has its own cons. It requires plenty oftime and

excess efforts. But even after that there is noguarantee that the objects will be

sorted precisely and therewill be 100% accuracy in it. In some industries like

thepharmaceutical industry objects are produced according tobatches and when

this sorting fails, the entire batch needs tobe discarded. It wastes a lot of efforts

and cost of producingthe objects. So to assist these industries, a system that will

sortobjects automatically according to their color can be designed and the result

obtained will be totally accurate. Color sorting machine, works under IOT.

Here IOT (Internet of Things) implies a combination of interrelated computing

devices, Mechanical and digital machines. IOT encourages the communication

between the devices which is famously know as machine to machine

communication. In the world automation is increases with the help of IOT. IOT

have both advantages and disadvantages. Although it contains few

disadvantages, it is widely used. Time saving is the main advantage,

soconsumers are mainly attracted to it. IOT based colored products sorting

machine is an effective machine which works under the mechanism of sorting.

The proposed system works on a microcontroller which is widely used in the

industries. The system will work when any colored object is placed on the

conveyor belt. The object can be colored Red, Blue, Green or a mixture of any

of these colors. A color sensor is attached on the side of conveyor belt for

detection of the object. The color sensor will read the color values in terms of

RGB percentage of the object color and compare it with a predetermined value

threshold already programmed using the microcontroller. If the color sensor will

find the color to be above the threshold it will instruct the microcontroller to

activate the piston right next to the color sensor. The piston will now push the

object into a bucket right in front of it. If the color sensor reads a different

value,then the set threshold it will just pass it forward where another piston will

sort the product in another bucket. The system will become more complex if we

want to increase the number of objects sorted based on different colors.

Microcontroller has been used to control the various operations. It is a very

useful in a wide variety of industries with the help of amicrocontroller

especially into the packaging section.

Automatic sorting machine enhances the efficiency, practicality, and also the

safety of the operators. It ensures that the remarkable processing capacity is also

peerless performance including the color detection. Although we need to add a

higher speed DC motor and sensor with an appreciable response to speed up the

system for the industrial application. The model can be improved by making

some changes into the program and components. Some suggestions

are given for improving the system like adding a load cell for the measurement

and control of weight of the product. A counter can be used for counting the

number of products. System speed can be increased accounting to speed of

production. Adding more sensors for quality control will benefit. The sensor can

be changed according to the application as a future scope of this project. DC

motor can be replaced with a stepper motor. Microcontroller can be

replaced with a PLC. Segregation which is based on size can be done by

installation of sieves of various sizes PH sensors installed for food industry

application to check the freshness.

their coloration even they'll be unique in coloration. Many paintings

environments aren't suitable for manual sorting and a few areas are risky for

humans to paintings on. Consequently to avoid the unstable work, time

consumption and hard paintings catch 22 situation. This prototype is built as a

simple digital gadgets like microcontroller for processing, Servo motors for
actions and coloration sensor for recognizing exclusive colored

devices.

according to different conditions like budget and scope of industry. Some more

components that can be included to make the system better are robotics systems,

microcontroller based system, sensor based system and pneumatic based

system, etc. Further the accuracy of the system depends mostly on the use and

type of color sensors. Currently existing systems usually contain an RGB based

color detection system. The ratio of RGB declares the exact color of the product

that is being sorted. In current systems, use of different technology is made \

according to budget and scope of industry. It includes robotics systems,

microcontroller based system, sensor based system and pneumatic based

system, etc. In currently existing systems, use of different technology is made

according to budget and scope of industry.It includes robotic systems,

microcontroller based systems,sensor based system and pneumatic based

system,etc. Automatic colour sorting machines are expensive ,So our proposed

method is developed to design machines are low cost,and and more accuracy

8.CONCLUSION
The suggested framework will be a demo rendition which
gives expense effective, taking less time and technically the
easiest way for differentiating objects. This framework
utilizes Arduino Uno which makes this model simple to utilize
which is more additional effective. The main failure will be
caused if the sensing of object according to color is not done.
Therefore, it is very important to have proper and checked
sensors. Further, making desirable changes it can be used in
small scale and large scale industries as well.

8.FUTURE SCOPE
Velocity of the gadget can be
improved accounting to the speed of
manufacturing.
The system can be used as a best
controller via adding more sensors.
The sensor can be modified consistent
with the type of product.
It's miles very useful in wide kinds of
industries along with the assist of PLC
and Scada, specially inside the
packaging section. Automated sorting
machine complements performance,
practicality, and protection of
operators. It ensures notable processing
Ability in addition to peerless
performance such as coloration
detection. Of course, we want to add
excessive speed dc vehicles and
sensors with considerable reaction to
hurry up the system for industrial Utlity
