INTRODUCTION
In the rapidly evolving landscape of industrial automa- tion, the integration of advanced technologies to
streamline operations has become essential. One of the most crucial elements in improving efficiency and
reducing human error in manufacturing and logistics is the automation of material handling systems.
Conveyor belts, which have long been a fundamental part of production lines, are now being enhanced with
smart technologies to automate sorting, counting, and other tasks traditionally performed by human workers.
This paper focuses on the design and implementation of an automated conveyor belt system that utilizes
Infrared (IR) sensors for counting and sorting items. The system integrates the widely used Arduino UNO
microcontroller and a Pro- grammable Logic Controller (PLC) to control the system’s operations, ensuring
both flexibility and reliability in a variety of industrial environments. By automating the counting and sorting
processes, the proposed system aims to reduce the need for manual labor, minimize errors, and enhance
operational efficiency.

The primary goal of this research is to develop a cost- effective, reliable, and scalable automated sorting
system. As industries continue to demand faster, more efficient production cycles, manual sorting methods
struggle to keep pace with the growing needs of modern manufacturing. Manual processes are time-
consuming, prone to human error, and inefficient when dealing with high-volume production. In contrast, au-
tomation offers the potential for continuous operation, greater speed, and higher accuracy, while reducing
operational costs and improving product quality.
The key technology used in this system is Infrared (IR) sensing, which provides a non-contact method for
detecting objects as they move along the conveyor. IR sensors are commonly used in automated systems for
object detection and counting, owing to their simplicity, low cost, and reliability. In the proposed system, IR
sensors will detect the presence and size of items as they pass, sending signals to the Arduino UNO
microcontroller, which processes the data and actuates a sorting mechanism based on predefined criteria.
Additionally, the integration of a PLC enables more ad- vanced control functions, such as motor speed
regulation and synchronization between the conveyor belt, sensors, and sorting mechanism. This hybrid
approach, combining the flexibility of Arduino with the robustness of PLC systems, provides a scalable
solution that can be adapted to various production environments.
The system’s performance will be evaluated based on key metrics such as sorting accuracy, operational speed,
system reliability, and error rates. This research not only seeks to demonstrate the feasibility of automated
sorting on conveyor belts but also aims to contribute valuable insights into the application of IR sensors,
microcontrollers, and PLCs in industrial automation.
By automating the sorting and counting processes, the proposed system will offer industries a reliable, cost-
effective solution that improves production throughput and quality while reducing human intervention.
Ultimately, this paper highlights the potential of automation technologies in transforming man- ufacturing
processes, providing a pathway toward smarter, more efficient industrial operations.
LITERATURE REVIEW
Automation in manufacturing and material handling has seen significant advancements over the last few
decades. With the advent of Industry 4.0, there has been a profound shift towards integrating cyber-physical
systems, the Internet of Things (IoT), and automation technologies. Conveyor belt sys- tems, which have been a
vital component in industrial material handling, have greatly benefited from these advancements, leading to
the development of automated systems capable of performing sorting, counting, and categorizing tasks with
high precision and speed. This section reviews the state-of- the-art developments in conveyor belt systems, IR
sensors, microcontrollers, and PLCs in the context of automated sorting and counting.
Automation in Industry
The rise of automation has transformed industrial practices, reducing reliance on manual labor and
improving speed, accuracy, and productivity. According to Vukovic´ et al. [1], au- tomation has significantly
enhanced manufacturing efficiency, particularly in repetitive tasks such as sorting, counting, and quality
control. Industrial automation technologies, including robotics and programmable logic controllers (PLCs),
have been essential in optimizing production processes and improv- ing consistency. Automated systems not
only reduce human errors but also operate continuously without fatigue, thereby increasing throughput and
ensuring consistent product quality. Automation technologies in material handling systems are crucial for
industries such as automotive manufacturing, lo- gistics, and food processing, where efficiency and speed
are paramount. As manufacturers aim to scale production while maintaining high quality, automation
becomes essential for ensuring that the growing demand for faster production cycles can be met without
compromising product standards.
Conveyor Belt Systems in Automation
Conveyor belts are integral to automated material handling systems. They are designed to transport goods

from one point to another, reducing the need for manual labor and ensuring the smooth flow of materials across
different stages of production. The use of conveyor belts has been commonplace in industries like automotive,
logistics, and packaging, where large quantities of goods need to be efficiently moved through various stages
of production [2].
Recent innovations in conveyor belt technology focus on automation, where integrated sensors enable real-
time mon- itoring and control. According to Kuo et al. [2], automated conveyor belts are equipped with various
sensors to monitor the presence, position, and characteristics of items. The ability to detect object dimensions,
speed, and orientation allows the system to perform tasks like sorting and counting efficiently. This reduces the
need for manual inspection and ensures the accuracy of the process.
For sorting applications, powered roller conveyors, which allow easy integration with sensors, are often
selected. These conveyors are capable of handling heavier and larger items, making them ideal for diverse
sorting tasks. Automation of these tasks improves the accuracy of sorting operations, reducing the chances of
human error and increasing the overall efficiency of the production line.
IR Sensors in Automation
Infrared (IR) sensors have become an integral component of automated systems due to their non-contact
nature, cost- effectiveness, and ease of integration. IR sensors work by emitting infrared light and detecting the
reflection of that light when it hits an object. This simple detection method makes IR sensors ideal for use in
automated counting and sorting applications, where detecting the presence and size of items is crucial. Zhou
et al. [3] highlight that IR sensors are widely used in automated material handling systems, including
warehouses, packaging, and assembly lines.
There are two main types of IR sensors: transmissive and reflective. Transmissive IR sensors consist of an
emitter and a detector placed across from each other. When an object interrupts the infrared beam, it triggers a
response from the system. Reflective IR sensors, on the other hand, have both the emitter and detector on the
same side, with the detector detecting the amount of reflected infrared light from an object. Reflective IR
sensors are commonly used in sorting systems, as they are less susceptible to alignment errors compared to
transmissive sensors [3].
Ahmed et al. [4] note that while IR sensors offer many advantages, including their affordability and ease of
use, they are also susceptible to environmental factors such as ambient light, dust, and misalignment. These
challenges need to be accounted for during system design to ensure that the sensors provide accurate readings
under various industrial conditions.
Programmable Logic Controllers (PLCs) in Industrial Au- tomation
PLCs have been the cornerstone of industrial automation for decades due to their robustness, reliability, and
ability to con- trol complex processes. A PLC is a digital computer designed to automate electromechanical
processes, such as the control of machinery on factory assembly lines. The widespread use of PLCs in
industrial automation can be attributed to their capacity to handle large amounts of input and output data,
control actuators, and integrate with sensors [5].
In automated sorting systems, PLCs are used to manage high-level control tasks such as coordinating the
operation of motors, controlling the timing of sorting actions, and ensuring system synchronization. They also
communicate with various devices, such as IR sensors and sorting actuators, ensuring that each component
functions correctly. As noted by Siemens [5], PLCs are essential for managing complex control tasks that
cannot be easily handled by simpler microcontroller-based systems like Arduino.
For instance, in the proposed conveyor belt system, the PLC will control the motor’s speed and synchronize
the actions of the sorting mechanism, ensuring smooth operation without errors. By leveraging PLCs,
industrial systems can be scaled and made more reliable, with the added advantage of integrating real-time
monitoring and fault detection systems.

Arduino in Industrial Automation
While PLCs are widely used in large-scale industrial au- tomation, microcontrollers like Arduino have gained
popu- larity for smaller-scale applications and prototyping. Arduino is an open-source platform that provides a
simple, flexible, and affordable solution for automating tasks in manufacturing, robotics, and other fields [4].
The Arduino UNO, in particular, is a widely used microcontroller that allows developers to easily integrate
sensors, actuators, and other electronic com- ponents for automation.
Arduino systems are ideal for projects where flexibility, ease of programming, and rapid prototyping are
needed. Arduino- based systems are often used in educational settings, DIY projects, and small-scale industrial
applications. In this study, the Arduino UNO will be used to process signals from IR sensors and control the
sorting mechanism, providing a low- cost but highly flexible solution for the automated conveyor belt system.
Although not as industrial-grade as PLCs, Arduino-based systems offer a high level of customization,
allowing users to develop unique control algorithms and adapt the system to various industrial needs. The
ability to program Arduino systems in an easy-to-understand language, combined with a large community of
developers and resources, has made it an attractive option for automation tasks that require flexibility [4].
Challenges in Automated Sorting Systems
Despite the advancements in automated sorting and count- ing systems, several challenges remain. One of the
primary challenges is sensor interference, where environmental factors such as ambient light, dust, and
misalignment can affect the accuracy of IR sensors [4]. To address these issues, careful calibration of
sensors and system design is required to minimize the impact of external factors.
Another challenge is the integration of components, particu- larly when combining different technologies such
as Arduino and PLCs. Ensuring seamless communication between sen- sors, controllers, and actuators is
crucial for the success of the system. Improper integration can lead to delays, inaccuracies, or system failures.
Lastly, system scalability is a common limitation in auto- mated sorting systems. As production volumes
increase, the system must be able to handle a higher throughput without sacrificing accuracy or speed. The
scalability of the proposed system is enhanced by the use of both Arduino and PLCs, which allows for
flexibility in adapting the system to different operational requirements.
METHODOLOGY
The design and implementation of an IR sensor-based counting and sorting conveyor belt system is a multi-
phase process that involves hardware design, integration of sensors and control systems, and software
development. This section outlines the overall approach for developing the automated conveyor belt system,
including the materials used, system design, integration of key components, and testing procedures.
System Design
The automated conveyor belt system is designed to handle material transport, object detection, counting, and
sorting operations in an industrial environment. The system consists of several key components, each of which
contributes to the overall functionality of the system. These components are integrated to work in harmony,
ensuring efficient and accurate operation.
The system’s primary function is to move items along the conveyor belt, detect their presence and size using
IR sensors, and sort them into predefined categories based on specific cri- teria. The IR sensors provide the
system with data on the size and presence of objects, while the Arduino microcontroller processes this
information to control the sorting mechanism. Additionally, a PLC is used to manage the system’s motor
control, synchronization of various components, and higher- level functions such as error handling.

Materials Used
Several materials and components were selected for the construction and operation of the system. These
components were chosen to ensure durability, efficiency, and ease of integration.
Mechanical Components:
DC Motor (12V, 33 rpm): Used to drive the conveyor belt and regulate its speed. A stepper motor can also
be employed for more precise control.
Conveyor Belt: A flexible PVC or rubber belt is used to transport items along the conveyor. The belt
material was selected to ensure smooth operation and minimal friction.
Frame: A sturdy metal frame is used to support the entire system, including the motor, sensors, and
conveyor belt. The frame must be durable and resistant to wear and tear.
Bearings: Bearings are used to support the rotating components, ensuring smooth movement and preventing
misalignment of the conveyor belt.
Actuators: Motors or pneumatic actuators are used for sorting items once they are detected by the IR
sensors.
Electrical Components:
IR Sensors: Reflective IR sensors are used to detect the presence of objects on the conveyor belt. These
sensors are strategically placed along the conveyor to detect items as they move through the detection zone.
Arduino UNO: The Arduino UNO microcontroller pro- cesses the input from the IR sensors and controls
the sorting mechanism. It is programmed to read the sensor data and execute sorting actions based on
predefined criteria.
Programmable Logic Controller (PLC): The PLC is used to manage high-level control tasks, such as
motor speed control, coordination of the sorting mechanism, and communication between the sensors and
actuators. It ensures that the system operates in a synchronized manner and handles complex control
processes.
Relay Modules: These modules are used to control the switching of electrical components such as motors
and actuators.
Power Supply: A Switched Mode Power Supply (SMPS) is used to provide a stable power source for all the
electronic components, ensuring consistent operation.
System Integration
The integration of various components is critical for the successful operation of the system. The following
steps outline how the different parts of the system work together:
Conveyor Belt and Motor: The conveyor belt is driven by a 12V DC motor, which is controlled by the PLC.
The mo- tor speed is adjusted according to the operational requirements. The motor’s speed and direction can
be fine-tuned using the PLC to ensure that items are moved at the optimal speed for sorting.
IR Sensors: The IR sensors are placed at strategic locations along the conveyor belt to detect the presence of
items. These sensors work by emitting infrared light and detecting the reflection of this light when it
encounters an object. The sensors send digital signals to the Arduino, which processes the data and triggers
sorting actions. If an item interrupts the IR beam, the Arduino counts it as a detected object and updates the
count.

Arduino UNO: The Arduino UNO microcontroller plays a central role in the system by processing signals
from the IR sensors and controlling the sorting mechanism. The Arduino is programmed to handle sensor data,
keep track of item counts, and trigger sorting actions when certain conditions are met (e.g., an item of a
particular size or type). The Arduino also communicates with the PLC to ensure synchronization with the
motor control system.
Sorting Mechanism: Based on the sensor data, the Ar- duino activates the sorting mechanism. The sorting
mechanism is typically an actuator (e.g., a motorized gate or pneumatic cylinder) that redirects items to
different bins or categories. Items are sorted based on predefined criteria such as size, type, or material. Once
an item is detected by the IR sensor, the Arduino determines whether it meets the sorting criteria and activates
the corresponding actuator to divert the item.
Fig. 1. System Block Diagram
PLC: The PLC manages high-level control functions, including motor control, synchronization between the
com- ponents, and fault detection. It also handles real-time data exchange between the Arduino and other
components. The PLC ensures that the system operates smoothly, coordinating the actions of the motor,
sensors, and sorting mechanism. Additionally, the PLC manages error handling, such as dealing with sensor
malfunctions or actuator failures.
Software Development
The software development for the system is divided into two main parts: the programming of the Arduino
UNO and the configuration of the PLC.
Arduino Programming: The Arduino code is responsible for processing data from the IR sensors, keeping
track of the item count, and controlling the sorting mechanism. The program uses basic input-output
operations to read sensor values and trigger the actuators. The following steps outline the key functions of the
Arduino code:
Sensor Input Handling: The Arduino reads input from the IR sensors to detect objects. The sensors send a
LOW signal when they detect an object passing through the detection zone.
Counting: Each time an object is detected, the Arduino increments the count. The count is displayed on an
LCD or LED screen, providing real-time information about the number of items detected.
Sorting Logic: The Arduino is programmed with sorting criteria. If an item meets the defined conditions
(e.g., size, shape), the Arduino activates the corresponding actuator to divert the item to the correct bin.
Debouncing: The code includes debouncing techniques to avoid false readings due to sensor noise or
multiple triggers caused by a single object.
PLC Programming: The PLC is programmed to control the motor, manage real-time data flow, and ensure that
the sorting mechanism works in sync with the conveyor belt. The PLC code consists of ladder logic diagrams

that define how inputs (sensor signals) and outputs (motor control and actuator activation) interact. The key
functions of the PLC code are:
Motor Control: The PLC regulates the speed and direc- tion of the conveyor belt motor.
Synchronization: The PLC ensures that the actions of the IR sensors, Arduino, and actuators are properly
coor- dinated.
Error Handling: The PLC monitors the system for faults, such as sensor malfunctions or actuator failures,
and takes corrective action when necessary.
Testing and Evaluation
Once the system is designed and integrated, it undergoes rigorous testing to evaluate its performance under
various conditions. The testing process includes the following steps:
Sensor Accuracy Test: The IR sensors are tested to ensure they accurately detect items as they pass through the
detection zone. The system’s response time is also measured to ensure that items are counted and sorted
without delays.
Sorting Accuracy Test: The sorting mechanism is eval- uated based on its ability to accurately divert items to
the correct bins. The sorting speed and precision are measured to determine the efficiency of the system.
System Reliability Test: The system is run continuously for extended periods to evaluate its reliability and
identify po- tential issues such as motor overheating, sensor malfunctions, or actuator failure. The system is
also tested under different operational conditions to assess its robustness in real-world environments.
Performance Metrics: Key performance metrics such as sorting speed, counting accuracy, and error rates are
recorded and analyzed to evaluate the system’s overall efficiency. Data collected from testing will be used to
identify areas for improvement and optimize system performance.
RESULTS AND DISCUSSION
This section presents the results obtained from testing the IR sensor-based counting and sorting conveyor belt
system. The performance of the system was evaluated based on several key metrics, including counting
accuracy, sorting speed, system reliability, and error rates. The discussion also highlights the challenges
encountered during the testing phase and provides an analysis of the system’s overall effectiveness in real-
world industrial applications.
System Performance Evaluation
The performance of the automated conveyor belt system was assessed under various conditions to determine its
suitability for industrial applications. The testing was conducted with items of different sizes and materials to
evaluate the system’s adaptability and efficiency in sorting and counting.
Counting Accuracy: One of the primary goals of the system was to achieve high accuracy in counting items as
they passed along the conveyor belt. During testing, the IR sensors successfully detected objects with high
precision, triggering accurate counts for each item detected.
Results: The system achieved a counting accuracy of ap- proximately 90% during the tests. The discrepancy
between the expected and actual counts was minimal, with errors typically occurring when items were very
close together or moved too quickly along the conveyor. These errors were most noticeable when the objects
were of similar size, causing potential interference between the sensors’ detection beams.
Discussion: The relatively high counting accuracy indicates that the IR sensors, coupled with the Arduino
UNO’s pro- cessing power, can effectively handle the task of counting in most industrial settings. However,

the system could be further improved by enhancing sensor alignment and incorporating algorithms to handle
high-speed or clustered items more effectively. Additionally, adjusting the sensor’s sensitivity may help in
reducing errors caused by objects moving too quickly or being too close to each other.
Sorting Speed: The sorting speed was measured by the time it took for items to be detected, counted, and
directed to the appropriate bin. The system was tested under different speeds of the conveyor belt to simulate
various industrial environments.
Results: The sorting speed varied based on the type of item and the speed of the conveyor belt. At an average
conveyor belt speed of 0.5 meters per second, the system was able to sort approximately 50 items per
minute. The sorting mechanism was able to direct items into bins with minimal delay, demonstrating the
system’s capability to handle moderate production speeds.
Discussion: While the system demonstrated a satisfactory sorting speed, the performance could be further
enhanced by optimizing the actuator’s response time and refining the com- munication between the Arduino
and the PLC. Additionally, the sorting speed could be improved by adjusting the conveyor belt speed based on
the type of items being handled. For faster production lines, using more powerful actuators or faster motors
may be necessary to maintain high throughput without delays.
System Reliability: System reliability was assessed by running the conveyor belt system continuously for
extended periods, simulating a real-world production environment. The goal was to ensure that the system
could operate without significant breakdowns or errors.
Results: The system operated reliably for up to 20 minutes under continuous testing conditions. During this
period, the sensors and actuators functioned as expected, with minimal downtime. However, after prolonged
use, some occasional misalignments were observed, primarily due to the movement of the conveyor belt,
which led to slight inaccuracies in object detection.
Discussion: The results show that the system is reliable for short to medium-duration operations. However, for
continuous or long-term industrial use, improvements are needed in the mechanical setup, particularly with the
alignment of the con- veyor belt and sensors. Ensuring that the conveyor belt and sensors remain stable and
aligned during operation will be crucial for long-term reliability. Additionally, regular main- tenance and
calibration of the sensors would help maintain optimal performance.
Error Rates and Fault Handling: Error rates were cal- culated based on the number of items that were
incorrectly counted or sorted. Faults were also observed when sensors failed to detect items due to
environmental factors like dust or improper sensor placement.
Results: The system had an error rate of around 5% due to issues such as sensor misalignment,
environmental interfer- ence, and occasional actuator failure. The sorting mechanism occasionally misdirected
items when the system’s sensors failed to detect the presence of objects correctly.
Discussion: The primary sources of errors were envi- ronmental factors such as dust, ambient light, and sensor
misalignment. To mitigate these errors, the system can be further optimized by adding dust shields around the
sensors or incorporating more advanced sensors, such as ultrasonic or laser sensors, which are less affected
by environmental interference. Furthermore, the integration of error-handling routines in the software,
including fault detection and system recalibration, could improve the system’s overall accuracy and reliability.
DISCUSSION OF CHALLENGES
While the system performed well in most tests, several challenges were encountered during the
implementation and testing phases. These challenges, and the solutions imple- mented to address them, are
discussed below.
Sensor Alignment and Calibration: One of the primary challenges in achieving high counting accuracy was
ensuring that the IR sensors were correctly aligned and calibrated. Misalignment or improper calibration led to

false readings and inaccuracies in object detection.
Solution: The sensors were repositioned during testing to optimize their detection range. Additionally, the
software was adjusted to include calibration routines that allow for real-time sensor adjustments based on
varying environmental conditions.
Environmental Interference: The IR sensors were sus- ceptible to interference from ambient light and dust. This
led to occasional failures in detecting objects accurately, particularly in environments with fluctuating lighting
conditions.
Solution: The system was equipped with protective covers to shield the sensors from dust and direct sunlight.
Further improvements could involve using sensors with built-in filter- ing capabilities or switching to different
sensor types, such as ultrasonic sensors, that are less sensitive to ambient light.
Sorting Actuator Delay: The sorting actuator occasion- ally exhibited delays in activating when an item met the
sorting criteria. This issue affected the sorting speed, especially when the conveyor belt was moving at higher
speeds.
Solution: The sorting mechanism was optimized by adjust- ing the actuator’s control logic in the Arduino
software. The use of faster actuators or more efficient sorting gates could further improve the response time.
System Improvements and Future Work
Based on the results obtained from testing, several improve- ments can be made to enhance the performance of
the system:
Advanced Sensor Technology: Replacing the IR sensors with more robust sensor types, such as ultrasonic
or laser sensors, could reduce errors caused by environmental interference and improve detection accuracy,
particularly in environments with variable lighting.
Enhanced Sorting Mechanism: Upgrading the sorting mechanism with faster, more responsive actuators
would help improve sorting speed and reduce delays.
Error-Handling Mechanisms: Implementing additional error-handling and self-calibration routines in the
soft- ware could help the system adapt to changing conditions and improve overall system reliability.
Integration of Machine Learning: In the future, inte- grating machine learning algorithms for dynamic
sorting could help the system automatically adjust to different types of items and sorting criteria, further
enhancing flexibility.
Long-Term Durability: Ensuring that the system is capable of handling continuous operations for extended
periods will require improvements in sensor and actuator durability, as well as the design of more robust
mechan- ical components.
CONCLUSION
The IR sensor-based counting and sorting conveyor belt system demonstrated good performance in terms of
count- ing accuracy, sorting speed, and system reliability. While the system is suitable for small- to
medium-scale industrial applications, further improvements in sensor technology, sort- ing mechanisms, and
error-handling routines will enhance its efficiency and reliability. This research provides a solid foundation
for the development of automated sorting systems, with potential for future enhancements that can address the
challenges encountered during testing. By integrating more advanced technologies and optimizing system
components, this approach can be scaled to meet the growing demands of modern industrial environments.
