Automatic power factor_improvement_and_monitoring_by_using_plc[1]ferozpatowary
This document describes a project to implement automatic power factor improvement and monitoring using a programmable logic controller (PLC) and supervisory control and data acquisition (SCADA) system. A group of six students will connect capacitor banks in parallel with various loads to correct low power factors. A PLC will control the capacitor banks based on power factor measurements from a power meter. The students will design input and output modules for the PLC, develop ladder logic programming, and create a SCADA model for monitoring. The goal is to develop a low-cost automated system using PLC and SCADA to replace manual power factor correction methods. This will improve efficiency in industrial plants by maintaining a high power factor near unity.
Automatic Power Factor Improvement by Using PLC & SCADAferozpatowary
Power factor correction (PFC) is a process of negotiating the unwanted effects of electric loads that
create a power factor less than one. Power factor correction may be applied either by an electrical power transmission utility to enhance the efficiency of transmission network. In this paper three transformers of different ratings have been used which acts as inductive load each of which produce different power factor variation. The power factor of the supply line is directly monitored by the Power Meter which is connected in parallel to the supply line. The value of the capacitance (capacitor bank) required for correcting the power factor variation due to each transformer and their
combination is found out separately. Capacitor bank for the respective load is triggered by using PLC, which connects the capacitor bank parallel to the load and thereby bringing the power factor near to unity. This paper represents the most effective automatic power factor improvement and monitoring by using static capacitors which will be controlled by a PLC with very low cost although many existing systems are present which are expensive and difficult to manufacture. In this study, many small rating capacitors are connected in parallel and a reference power factor is set as standard value into the PLC. Suitable number of static capacitors is automatically connected according to the instruction of the PLC to improve the power factor close to unity. Some tricks such as using resistors instead of potential transformer and using one of the most low cost PLC SIEMENS S7-200 CPU215 DC/DC/DC which also reduce programming complexity that make it most economical system than any other controlling system.

Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

ABSTRACT
The restaurant is now gaining more importance in terms of automation. The usual procedure used
for food ordering in restaurants is a manual process. It involves the waiters noting down the menu
from customers, transferring the orders to the kitchen, serving the menu and finally preparing bills.
This process even though looks simple, is prone to human errors while note making and delays
involved. So the customers end-up with unsatisfactory service. Considering this fact and with an
aim to improve efficiency and reduce errors in conventional food ordering system, new technology
is introduced to automate the process. The ordering process is made simple through which the
customer can order the food item from the table itself. It consists of Mobile App and LCD display
to order the food item and to display the ordered food item to the customer respectively. The
ordered food item will be transferred to the kitchen using the Bluetooth Module. The serving
process consists of food serving conveyer belt which is used to serve the foods to the customer
depending upon their order. The conveyer belt uses arduino microcontroller for programming. The
cost of the ordered food item will get added up and the total bill amount will be shown to the
customer and it will be sent to the billing counter. Website will also be created for the restaurant.

CHAPTER 1
INTRODUCTION
1.1 Introduction
Restaurant is a place where people come, sit and eat meals that are cooked and served by the chef
and the waiters respectively. In traditional restaurant system, orders are taken by a waiter and they
bring the food when it is ready. After eating the food, customers will pay the bill. This system relies
on large numbers of manpower to handle customer reservation, inquiry about them, ordering food,
placing order on table, reminding dishes of customer. Currently, there are a lot of ways of serving
the customers. For instance, waiter serving system, robot serving system, self-carrying system (fast
food), pen-and-paper self-ordering system, etc. These systems are made in order to get attraction
from customers and to reduce the need of hiring more employees in their workplace. When there is
a conveyer belt that can carry food, it will strictly reduce the need of hiring more employees.
Therefore, there is propos system. The proposed system reduces the man power and makes the
whole process in the restaurant to be done automatically starting from welcoming the customer to
payment of bill. The display system consists of three main blocks. First block deals with ordering
process through which the customer can order the food item without the need of the mobile app.
The customer table is provided with the app and LCD display using which the customer can type
the item code and can see the ordered food item along with cost respectively. The second block is to
serve the ordered food to the customer. It is done by using the food serving conveyer belt. It will
modify the real time problem of time delay and delivering of incorrect food item. It consists of the
dc gear motor which moves according to the sensor output. The conveyer belt consists of proximity
sensor to count the wheel rotation and IR sensor for obstacle detection. The third block is for
payment of bill amount. The cost of the ordered food item will be displayed to the customer at the
time of ordering itself and if the customer finished ordering, the total amount of the ordered food
item will be calculated and the entire bill amount will be displayed to the customer. The other
technique in this paper includes the common display of available food item with their code so that
the customer can be aware of the menu. There will be a helping technique available at each
customer table which is used by the customer to order the food item. In this technique the
instruction for the entire process will be played at the time of ordering the food item. This system
replaces the conventional method in restaurant and it reduces the human need and makes the
13. 3| P a g e
process simple and efficient. This system is also meant for the attraction of the customer .By seeing
this technology the amount of customer will be increased and so the profit will be increased. The
main objective of this paper is
To order the food item without the need of the server
To serve the ordered food item to the customer automatically without any human need
To calculate the bill amount and to display the amount to the customer

1.3 System Discussion
In this section we will discuss about system process. There is some process.
1.3.1 Ordering System
The proposed system consists of mobile app, arduino, LCD display, Bluetooth Module for ordering
the food item. Mobile app and LCD display are placed in the customers table. Each food item will
be given a code; the customer can type the code of the food item using the app. The quantity of the
food item can be incremented and decremented using 1 or 2. The name of the food item, quantity,
and cost of the food item will be displayed in the LCD display placed in the table. The name of the
food item will be transmitted to the kitchen using Bluetooth Module and it will be displayed in the
kitchen LCD. The availability of the food item along with the code and cost will be displayed in
the common LCD display placed in the restaurant. When the customers occupy the table the
instruction will be played, so that the customer can order the food item according to the
instruction.
1.3.2 Serving Process
This system uses Conveyer belt to serve the food to the customer. The conveyer includes IR sensor.
There will be a display and mobile app on the customers table. Customer will be able to set up
menu by the mobile app and order shown on the kitchen monitor. Accordingly, to prepare the food
to serve. The prepared food will be placed on the conveyer belt and belt will reach the table. This
is serving process.
1.3.3 Restaurant Website and Android App
Webpage has been created for the restaurant for ordering the food item from their home place and
then it will be delivered to the customer. The webpage contains the details of restaurant, menu,
cost of the item and the ordering site. The ordering site contains the input box where customer
needs to enter the details of ordering. Mobile Android application is developed for the restaurant
and it will be provided to the customer so that they can easily order the food item.
15. 5| P a g e
1.4 Results and Discussion
This chapter provides the necessary information for Result and Discussion. In this section we will
discuss about system process. There is some process.
1.4.1 Ordering Process
Instruction for Ordering
When the customer occupies their table the LCD will show greetings to the customer and it will tell
to press 5 to read the instruction.
So, the customer has to press 5 if they want to read the instruction if the customer is familiar with
the instruction then they can move to the next step.
The instruction is as follows:
• Press start to start ordering.
• Type the item code of the food that they wish to order by seeing the menu list menu
displayed on the common LCD.
• Press 1 or 2 to increment and decrement the quantity.
Once the ordering is finished press submit to print the total amount. The common LCD display will
be present at the restaurant to display the food item that are present in the kitchen .The LCD display
will contain the details of item code, name of the food item and its cost.
Ordering Method
The item code, name of the food item and cost of it will be displayed in the common LCD kept at
the restaurant. By seeing that, the customer needs to type the item code by using the apps keypad
for eg., if they type ‘1’ using the keypad then ‘idly’ will be displayed on the LCD. Then the
quantity is given by means of + and – button. If + is pressed the quantity will be increase and if – is
pressed ,the quantity will be decrease. The cost of each ordered food will be simultaneously printed
on the LCD display. Once the first item has been ordered then the customer can precede the same
step for the next item. The customer can order any number of items at the time. This type of food
ordering will replace the conventional method of using pen and paper. It provides accurate means of
ordering system where there will be no error of changing the item and the customer no need to wait
for the server. The customer will also be aware of the cost of item while ordering the item.
16. 6| P a g e
1.4.2 Serving Process
When the conveyer is called it will be moved in a programmed path. For each rotation of the IR
sensor gets incremented, it will stay in the kitchen and get the order and then it will have delivered
to the ordered customer. When the obstacle is detected in its path, it will stop if the obstacle object.
1.5 Applications of the project
We are going to implement our system in restaurants to ease the serving and management system
of the restaurant and also give a technical touch which atomize the working of restaurant.
With slight modification in this project, this system can be widely used at different public places
like at canteens, hospitals, public transport, home, theatres etc.
1.6 Limitations
Status and feedback of order is not obtained.
Limited distance.
System may not work properly if tablet/Smartphone suffer a defect
Also may become a drawback if end users are not able to use the tablet/Smart phone devices.

CHAPTER 2
LITERATURE REVIEW
AUTONOMOUS ROBOT SYSTEM RESTAURNT [10]
There are some basic requirements in creating an autonomous mobile robot: openness, abstraction
and modularity. These requirements are crucial so that a new function of robot can be constructed
from small changes of hardware and software design. Line following based on Infrared (IR)
photoelectric sensor is the basic knowledge to construct an autonomous mobile robot. It is an
intelligent system to ensure that the robot moves according to the line, in which if it moves out of
the line, the position corrective feedback will send data to the microcontroller. In order to perform a
good line following robot, the principle of IR sensor should be followed. The robot build has to
detect the line in the shortest time.
Thus, the IR sensor has to produce the best output so that the information can be sent to the
microcontroller, and gives faster reaction. In order to improve system reliability and accuracy, the
received reflected light will convert into output signal voltage, which directly affected by the
distance between the reflector and the sensor. There is a threshold voltage, where the distance of IR
sensor and reflector is optimum. The output received from IR sensor will pass through a comparator
in order to compare the voltage and send data to microcontroller. The sensor installation mode will
also affect the performance of sensor. Basically, the distance between the IR set sensor and the black
line should be more than 5mm. Also, the IR sensor will be fixed perpendicular to the reflector.
SMART RESTAURANT: SURVEY ON CUSTOMER DEMAND AND SALSE,
FORECASTING. [13]
Demand forecasting is one of the important inputs for a successful restaurant yield and revenue
management system. Sales forecasting is crucial for an independent restaurant and for restaurant
chains as well. In this chapter a comprehensive literature review and classification of restaurant sales
and consumer demand techniques are presented. Sales prediction is very complex due to the impact
of internal and external environment. However, a reliable sales forecasting methodology can
improve the quality of business strategy. A range of methodologies and models for forecasting are
given in the literature. These techniques are categorized here into seven categories, also including
hybrid models. The methodology for different kinds of analytical methods is briefly described, the
18. 8| P a g e
advantages and drawbacks are discussed, and relevant set of papers is selected. Conclusions and
comments are also made on future research directions.
AUTOMATION IN RESTAURANTS: ORDERING TO ROBOTS IN RESTAURANT
VIA SMART ORDERING SYSTEM [14]
Automation is everywhere; in one of our last paper we proposed a serving robot in restaurant to
automate the restaurants. In that paper we discussed some issues in existing serving robots in China
and Japan, and ordering to a robot is one from that issues. This paper is focusing on introducing
ordering system along with robotic waiter in restaurants in India. It is a web based application that a
customer can open on their smart phone. This system will help restaurants and hotels to increase
their star rating and reduce the human error at the time of taking orders. Already hotels are doing
new experiments to get notice by customers. For that they are registering in online applications also.
Our application is basically for the robotic restaurants to automate them.
INTELLIGENT RESTAURANT SYSTEM SMARTMENU. [15]
Digital technology is transforming business in many sectors, including restaurant systems and
service processes. Customers may recognize the replacement of paper-based menus with digital ones
as a first step of this process. Intelligent restaurant systems are an interesting application area for
merging and extension of cognitive capabilities with both intra-cognitive and inter-cognitive
communication. An intelligent restaurant system Smart menu, developed by Centria and Delitaz
Ltd., is an example of innovation which is based on merging and extending of cognitive capabilities.
These kinds of systems may change the everyday life in restaurants in the future. The system covers
the whole order process of a restaurant including the applications of the customer, the waiter, the
kitchen and the cashier. The first pilot systems were recently tested in several restaurants in Finland.
Piloting included also questionnaires and interviews analyzed by usability experts. In the future,
Smart menu may be extended to include also service robots in the system. The first demonstrations
of using service robot in a restaurant environment were already carried out.
DIGITAL ORDERING SYSTEM FOR RESTAURANT USING ANDROID. [10]
Nowadays web services technology is widely used to integrate heterogeneous systems and develop
new applications. Here an application of integration of hotel management systems by web services
technology is presented. Digital Hotel Management integrates lots of systems of hotel industry such
19. 9| P a g e
as Ordering System Kitchen Order Ticket (KOT), Billing System, Customer Relationship
Management system (CRM) together. This integration solution can add or expand hotel software
system in any size of hotel chains environment. This system increases quality and speed of service.
This system also increases attraction of place for large range of customers. Implementing this
system gives a cost-efficient opportunity to give your customers a personalized service experience
where they are in control choosing what they want, when they want it – from dining to ordering to
payment and feedback. We are implementing this system using android application for Tablet PC’s.
The front end will be developed using JAVA Android and the backend will work on MySQL
database.
SMART AUTOMATED RESTAURANT. [13]
Smart Automated Restaurant provides an efficient and user friendly system. This system will solve
key problems faced by restaurants today through the use of technologies such as Mobile and Web
applications, Android applications and cloud computing. Restaurants have much inefficiency due to
human limitations that can be resolved through automation. This Smart Automated Restaurant
accomplishes this by providing two interfaces for the two types of users in restaurants; an Android
mobile application for customers and a web application for restaurant staff members. The Android
mobile application allows customers to have a seamless dining experience with features such as
finding available parking spaces easier through Internet-connected infrared proximity sensors in the
parking lot. Also finding available tables at the restaurant gets easier through the use of sensors.
Ordering dishes through an interactive menu and being able to pay the bill from their Android
phones are some of the other features. The web application provides staff members benefits such as
collecting data and statistics on the restaurants performance in real time and automating the order
placement system for waiters and cooks.

THEORETICAL OVERVIEW
We describe their theatrical overview of the project. For conveyer system, a DC gear motor device
is used control conveyer belt. This will command to conveyer so that it can do the required task like
moving forward, reverse, and stop. For obstacle system, we used obstacle and motion sensor to
detect any object and Arduino to process the data.
For automatic door opener system, we used motion sensor to detect object and open the door. For
Bluetooth app system, we used smartphone as a transmitter and Bluetooth module as a receiver. By
receiving customer data, Arduino process the data and shown it customer display and kitchen
monitor.

3.1.2 Bluetooth Module
Brief Description on Bluetooth module
The HC-05 is a very cool module which can add two-way (full-duplex) wireless functionality to your
projects. You can use this module to communicate between two microcontrollers like Arduino or
communicate with any device with Bluetooth functionality like a Phone or Laptop. There are many
android applications that are already available which makes this process a lot easier. The module
communicates with the help of USART at 9600 baud rate hence it is easy to interface with any
microcontroller that supports USART. We can also configure the default values of the module by
using the command mode. So if you looking for a Wireless module that could transfer data from your
computer or mobile phone to microcontroller or vice versa then this module might be the right choice
for you. However do not expect this module to transfer multimedia like photos or songs; you might
have to look into the CSR8645 module for that.

3.1.3 LCD
Brief Description on LCD modules
LCD modules are very commonly used in most embedded projects, the reason being its cheap price,
availability and programmer friendly. Most of us would have come across these displays in our day to
day life, either at PCO’s or calculators. The appearance and the pinouts have already been visualized
above now let us get a bit technical.
16×2 LCD is named so because; it has 16 Columns and 2 Rows. There are a lot of combinations
available like, 8×1, 8×2, 10×2, 16×1, etc. but the most used one is the 16×2 LCD. So, it will have
24. 14| P a g e
(16×2=32) 32 characters in total and each character will be made of 5×8 Pixel Dots. A Single
character with all its Pixels is shown in the below picture.
Now, we know that each character has (5×8=40) 40 Pixels and for 32 Characters we will have
(32×40) 1280 Pixels. Further, the LCD should also be instructed about the Position of the Pixels.
Hence it will be a hectic task to handle everything with the help of MCU, hence an Interface IC like
HD44780 is used, which is mounted on the backside of the LCD Module itself. The function of this
IC is to get the Commands and Data from the MCU and process them to display meaningful
information onto our LCD Screen. You can learn how to interface an LCD using the above
mentioned links. If you are an advanced programmer and would like to create your own library for
interfacing your Microcontroller with this LCD module then you have to understand the HD44780 IC
is working and commands which can be found its datasheet.

3.1.4 Servo Motor
A servo motor is an electrical device which can push or rotate an object with great precision. If you
want to rotate and object at some specific angles or distance, then you use servo motor. It is just
made up of simple motor which run through. If motor is used is DC powered then it is called DC
servo motor, and if it is AC powered motor then it is called AC servo motor. We can get a very high
torque servo motor in a small and light weight packages. Doe to these features they are being used in
many applications like toy car, RC helicopters and planes, Robotics, Machine etc.
Controlling Servo Motor: Servo motor is controlled by PWM (Pulse with Modulation) which is
provided by the control wires. There is a minimum pulse, a maximum pulse and a repetition rate.
Servo motor can turn 90 degree from either direction form its neutral position. The servo motor
expects to see a pulse every 20 milliseconds ( ms ) and the length of the pulse will determine how far
the motor turns.
26. 16| P a g e
Figure 3.4: Servo motor and Servo Motor Pinout
For example, a 1.5ms pulse will make the motor turn to the 90° position, such as if pulse is shorter
than 1.5ms shaft moves to 0° and if it is longer than 1.5ms than it will turn the servo to 180°. Servo
motor works on PWM (Pulse width modulation) principle, means its angle of rotation is controlled by
the duration of applied pulse to its Control PIN. Basically servo motor is made up of DC motor which
is controlled by a variable resistor (potentiometer) and some gears. High speed force of DC motor is
converted into torque by Gears. We know that WORK= FORCE X DISTANCE, in DC motor Force
is less and distance (speed) is high and in Servo, force is High and distance is less. Potentiometer is
connected to the output shaft of the Servo, to calculate the angle and stop the DC motor on required
angle.
Figure 3.5: Pulse Width Modulation
All servo motors work directly with your +5V supply rails but we have to be careful on the amount
of current the motor would consume, if you are planning to use more than two servo motors a proper
servo shield should be designed.

3.1.5 Motion Sensor
Brief Description on Motion Sensor
The PIR sensor stands for Passive Infrared sensor. It is a low cost sensor which can detect the
presence of Human beings or animals. This sensor has three output pins Vcc, Output and Ground as
shown in the pin diagram above. Since the output pin is 3.3V TTL logic it can be used with any
platforms like Arduino, Raspberry, PIC, ARM, 8051 etc..
The module can be powered from voltage 4.5V to 20V but, typically 5V is used. Once the module is
powered allow the module to calibrate itself for few minutes, 2 minutes is a well settled time. Then
observe the output on the output pin. Before we analyse the output we need to know that there are
two operating modes in this sensor such as Repeatable (H) and Non- Repeatable (L) and mode. The
Repeatable mode is the default mode.
The output of the sensor can be set by shorting any two pins on the left of the module as shown
below. You can also notice two orange colour potentiometers that can be used to set the sensitivity
and time which will be explained further below.

3.1.6 Obstacle Sensor
Brief about Obstacle Sensor
The Obstacle sensor module consists mainly of the IR Transmitter and Receiver, Opamp, Variable
Resistor (Trimmer pot), output LED in brief.
IR LED Transmitter
IR LED emits light, in the range of Infrared frequency. IR light is invisible to us as its wavelength
(700nm – 1mm) is much higher than the visible light range. IR LEDs have light emitting angle of
approx. 20-60 degree and range of approx. few centimeters to several feets, it depends upon the type
of IR transmitter and the manufacturer. Some transmitters have the range in kilometers. IR LED
white or transparent in colour, so it can give out amount of maximum light.
Photodiode Receiver
Photodiode acts as the IR receiver as its conducts when light falls on it. Photodiode is a
semiconductor which has a P-N junction, operated in Reverse Bias, means it start conducting the
current in reverse direction when Light falls on it, and the amount of current flow is proportional to
the amount of Light. This property makes it useful for IR detection. Photodiode looks like a LED,
with a black colour coating on its outer side, Black colour absorbs the highest amount of light.
29. 19| P a g e
LM358 Opamp
LM358 is an Operational Amplifier (Op-Amp) is used as voltage comparator in the IR sensor. the
comparator will compare the threshold voltage set using the preset (pin2) and the photodiode’s series
resistor voltage (pin3).
Photodiode’s series resistor voltage drop > Threshold voltage = Opamp output is High
Photodiode’s series resistor voltage drop < Threshold voltage = Opamp output is Low
When Opamp's output is high the LED at the Opamp output terminal turns ON (Indicating the
detection of Object).
Variable Resistor
The variable resistor used here is a preset. It is used to calibrate the distance range at which object
should be detected.

3.1.7 Push Button
Brief about Push Button
A push-button (also spelled pushbutton) or simply button is a simple switch mechanism for
controlling some aspect of a machine or a process. Buttons are typically made out of hard material,
usually plastic or metal.
Figure 3.8: Push Button
An electric switch is a device that interrupts the electron flow in a circuit. Switches are primarily
binary devices: either fully on or off and light switches have a simple design. When the switch is
turned off, the circuit breaks and the power flow is interrupted. Circuits consist of a source of
power and load.
3.1.8 Power Supply
Brief about Power Supply
The step-down converters are used for converting the high voltage into low voltage. The
converter with output voltage less than the input voltage is called as a step-down converter, and
the converter with output voltage greater than the input voltage is called as step-up converter.
There are step-up and step-down transformers which are used to step up or step down the
voltage levels. 230V AC is converted into 12V AC using a step-down transformer.

5.2 Software Description
Smart Restaurants is an affordable App solution for both restaurants and takeaways to have a unique
App to promote their business, advertise the food which they provide and allow customers to easily
order from.
At Smart Restaurants we have developed a range of Apps to work on both iPhone and Android so
that restaurants and takeaways can have an App to allow customers to download onto their smart
phone. Once they have downloaded the App they can then view the menu, add various food and
drink items to a basket and then easily place an order. This order is then sent through to the
restaurant or takeaway and will either be received through the printer we can provide or through the
Smart Ordering App, where the order can be viewed on either a smart phone or a tablet.
For the software development, the Visual Studio (VB) 6.0 software is used to design the Graphical
User Interfacing (GUI) of the project. Microsoft® Visual Studio® 6.0 is a powerful developer tools
suite for Windows and Web applications. The VB software is used to display the menu order from
customer at the computer screen. Another software was used is C language. The C language is used
to write a source codes for this microcontroller which is then will be compiled. When the program
can be successfully run no error in the source code, then the microcontroller will be programmed.

6.5 Future Enhancement
Through this project, we worked on how fast food and how much food can be
served without disturbance.
In this project we used the Bluetooth communication system. It is managed by an
Android app.
Here we use arduino, Bluetooth module, LCD, sensor.
We hope that at a very low cost in the smart cafe, we can serve food in less time.
6.6 Conclusion
Thus, if this system is implemented then the customer can easily order the food item without the
need of the server and without any error. It is recommended that use of touch screen instead of the
Mobile App and LCD screen. It can also include a module which provide greetings to the customer
such as showing welcome and thank you to the customer and using any money payment method to
pay the bill amount to respective account of the owner.
Integrating features of all the hardware components used have been developed in it. Presence of
every module has been reasoned out and placed carefully, thus contributing to the best working of
the unit. Secondly, using highly advanced device with the help of growing technology, the project
has been successfully implemented. Smart restaurant is developed in order to provide easy
interaction between customers through wireless technology. Thus the project has been successfully
designed and tested. Similarly, the system can also be implemented with Graphical LCD for
displaying the menu as we have used android phone. However the system becomes more bulky and
delicate to handle because each table is going to consist of such module for ordering.
