Programmable Sequential Load Operation Controlled By Android Application Project
Our project is designed to switch industrial loads by making use of
android app through logic control device programmed by user. The system
is made to be used in repetitive nature works. This remote controlling
task is achieved through the use of any android based device
(phone/tablet) running on an android OS.
Using programmable logical in order to achieve sequential switching of
loads proves a very costly operation. Here we propose a simple and cost
effective alternative to the issue by making use of 8051
microcontrollers. The controlling part is provided on an android
application.
Various tasks and in today’s industries work on repeated operations in
varied orders and intervals. Consider an example there a motor needs to
run after every 3 seconds. So for this purpose we program the
microcontroller to work in three different options: Set option, Manual
option and Auto option.
When the set option is selected, the system works according to time
intervals entered by user. In auto option the system now works as per
default time settings while in the manual option it operated on pressing
the selective switches as and when needed by the user. All modes and
status are displayed on an LCD display.
Our project thus provides very cost effective system to automate industry loads as an alternative to high cost PLC’s used.

Rf Controlled Robotic Vehicle With Metal Detection Project
Our project proposes a Metal detection robotic vehicle operated using Rf remote control wirelessly. The project demonstrates real life robotic vehicles used to detect land mines or other metal based objects on its path.The vehicle is fitted with a metal detection system that senses metals and then alarms the user about it through a buzzing sound of land mine possibility. The system works in conjunction with an 8051 series microcontroller to achieve this operation.
The push buttons are used to send commands to move the vehicle forward, backward, left and right. Two motors at receiving end operate the vehicle as per the commands received. As soon as a command is sent it gets transmitted through rf transmitter. At receiving end an rf receiver reads the command and passes it to an 8051 microcontroller for processing. The microcontroller then operates the motors to move the vehicle through a motor driver IC.
The metal detection system attached to the system detects any metal underneath it. On detection it automatically sends on a small buzzing alarm to notify user about it. Thus the metal detection system coupled with a robotic vehicle allows for operating the robotic vehicle on a 200 meter radius remotely through RF technology.

CNG/LPG Gas Leakage Detection & Accident Prevention System
Gas leakage tragedies and accidents have lead to heavy losses over the years. So it is very important to detect any gas leakage and prevent any accidents. So we here propose a system to detect LPG/CNG gas leakage scenarios and provide a security alert to intended users. We here propose to build the system using a MQ6 gas detection sensor and interface it with 8051 family microcontroller along with gsm modem for alerting via an SMS. Our system uses the gas sensor to detect any gas leakages. The gas sensor sends out a signal to microcontroller as soon as it encounters a gas leakage. The microcontroller processes this signal and sends out a signal to the gsm modem with required message details. The gsm modem now sends out an alerting sms to the authorized people so that they may handle the issue and look out for leakages.Hardware Specifications

Prepaid Electricity Billing Meter
Most of the energy meters are designed to bill as per the units of energy consumed. These meters need to be manually read by people in order to provide monthly/quarterly bills. We here propose a prepaid energy billing meter. The system is designed to allow amount of energy to be used as long as the account has balance pending. It also allows the operator to recharge the user account using GSM. The system first accepts account recharge and allows to use only limited units of energy as per recharge and then cuts off the supply. The prepaid electricity billing meter could be widely used to provide a new more customized electricity billing system, where users may recharge when they intend to use that facility. It also consists of a GSM modem that allows the operator to recharge the meter remotely using am SMS message. This puts forward an innovative electricity billing and “use as needed” electricity usage scheme. It also eliminates the need for manual electricity meter reading tasks.

Auto Lap Time Measurement System
Professional athletes, car drivers, bicycle riders need to keep practising by measuring their lap timings. While practising alone it is not possible for them to start and stop the stopwatch each time. At such time they need to focus on their performance instead of keeping track of the watch. So here we propose a system that can be work by user as a wrist watch. The system consists of a push button that needs to be pushed by user to start the system. On button press the microcontroller starts timer. The system also consists of an IR sensor pair, that is to be placed at finishing line. As soon as the user crosses the IR sensor pair it sends a signal to system to stop the timer. The time gets frozen in the system for user to check. The user may later reset the system using a push button provided on it.

Here we propose a system that allow user to unlock a door by entering a password remotely. We propose to use GSM technology ie through SMS. Our system allows user to send an sms with password in order to unlock a door. The door opens on receiving the right password. The system also alerts a registered user if wrong password is sent a number of times. The circuit consists of a gsm modem to receive sms data. It decodes the sms and sends it to an 8051 family microcontroller. The microcontroller reads the input and checks the password entered. It displays message stats on an LCD screen on receiving inputs. On receiving the right password it opens the door by activating the motor. On encountering wrong password multiple times the system sends an sms through the GSM modem to registered user that invalid attempts were made.

Mini IR Radar For Unauthorized Object Detection
Radar’s are used on airports as well as military bases for unauthorized object detection. Radars work on the principal of echo detection in order to detect objects. In air the refection of echo waves is measured on the basis of time taken to receive the signal. Based on this data the object distance is identified. We propose to simulate this concept using Infrared technology. Our system consists of a IR sensor radar that rotates constantly at 360 degrees. The radar constantly emits IR rays and measures reflection. On detecting reflection from any object within its range the radar stops and sends a signal. The radar also sends the angle at which the object was identified. We here use a small IR transmitter receiver pair. The pair is interfaced with microcontroller to control the circuit working. The microcontroller constantly receives the radar input. On sensing an object the radar sends an alert message to the microcontroller. The microcontroller now gets the data and also gets the radar direction in order to get angle at which object was detected.

Fire Plus Hazardous Gas Detection And Instant SMS Alerting System
Dangerous gas leakage as well as fires have caused wide damage to industries and economies in the past. These agents spread wildly and instant action needs to be taken as soon as such an event occurs. It is very important to detect a gas leak or fire as soon as it breaks out so that it can be prevented from spreading instantly. We here propose a system that detects gas leakage as well as fires as soon as they start and alerts the authorities automatically so that it can be stopped from spreading. Our system consists of gas sensor to detect any gas leakage as soon as it is encountered. The gas sensor sends a signal to the microcontroller as soon as gas leak is detected so that microcontroller can process it further. We use a temperature sensor in order to detect fire. The temperature sensor instantly sends a signal to the microcontroller on fire detection. Once the microcontroller receives signal from the sensors, it processes the input and then sends a signal to the gsm modem to send an sms to the intended authorities so that they may take appropriate action.Hardware Specifications

Ultrasonic Blind Walking Stick
Blind stick is an innovative stick designed for visually disabled people for improved navigation. We here propose an advanced blind stick that allows visually challenged people to navigate with ease using advanced technology. The blind stick is integrated with ultrasonic sensor along with light and water sensing. Our proposed project first uses ultrasonic sensors to detect obstacles ahead using ultrasonic waves. On sensing obstacles the sensor passes this data to the microcontroller. The microcontroller then processes this data and calculates if the obstacle is close enough. If the obstacle is not that close the circuit does nothing. If the obstacle is close the microcontroller sends a signal to sound a buzzer. It also detects and sounds a different buzzer if it detects water and alerts the blind. One more feature is that it allows the blind to detect if there is light or darkness in the room. The system has one more advanced feature integrated to help the blind find their stick if they forget where they kept it. A wireless rf based remote is used for this purpose. Pressing the remote button sounds a buzzer on the stick which helps the blind person to find their stick. Thus this system allows for obstacle detection as well as finding stick if misplaced by visually disabled people.Hardware Specifications

Automatic Unauthorized Parking Detector With SMS Notification To Owner
A large number of personnel are deployed to check for unauthorized parking and fine those owners. But owners evade the fine by various illegal means like bribing the personnel, threatening them etc. Towing vans need to manually search for illegally parked vehicles. This system requires large overhead costs in manpower payment, fuel and other physical surveillance. Here we propose a system that allows for automatic illegal parking detection and alerting. The system consists of integrating an RFID transmitter in every vehicle. RFID receiver circuit is mounted on every area where parking is not prohibited. If a vehicle is parked in an area where parking is not prohibited the rfid transmitter comes in rang of the receiver circuit. Once this happens the rfid reader reads the transmitter id and can instantly alert authority with area code so that authorities can directly arrive at the spot and sends an sms to the car owner about the fine imposed on the vehicle.Motion Based PC Video Game
In today’s world we like making games more interactive. So we try to incorporate more sophisticated human motion sensing to provide as input to those virtual games. This helps us to map human motions into computer games. So here we use an accelerometer for this purpose. An accelerometer allows to measure acceleration in three different directions. So on sensing motion it outputs voltage for x, y and z directions. This accelerometer can thus be used as a glove or handheld device to map user hand movement into computer games. Here we use accelerometer with a circuit that consists of capacitors to convert the analog voltage provided by accelerometer to digital voltage signals. We here use four comparators in non inverting and inverting mode used to convert 4 bit data at various orientations. Now this is connected to an RF encoder. So this data is transmitted by rf transmitter. Another with rf encoder is used to receive the input and decode the data using an HT12D connected to it. This decoder now decodes data and provides it to microcontroller for further processing. The microcontroller now processes this data and sends required commands to the computer. We here use a simple game designed in VVB 6 to map the inputs and display actions in the game.
Alcohol Sensing Display With Alarm Project
We here propose an alcohol sensing system that measures alcohol intake, displays percentage of alcohol and also sounds an alarm if it is above a particular threshold. Here we use an alcohol sensor circuit along with lcd display and a buzzer alarm. Our system first uses the alcohol sensor in order to detect alcohol. The sensor provides analog output. This analog output is now provided to the microcontroller for further processing. Based on the input the microcontroller calculates the percentage of alcohol and displays the same on an LCD display. It also sounds an alarm if the amount of alcohol exceeds a particular amount. Our system thus allows to measure amount of alcohol and then display percentage of alcohol measured. Also a alarm is sounded that indicates that measured alcohol is above a particular percentage.

Our proposed project uses sensors to sense the water level and then opens the dam gate (motor used to demonstrate as dam gate) according to the water level. Our system uses multiple water level sensors (float sensors) for this purposes. The sensors are mounted at three different levels in order to check water level and provide signals accordingly. When water reaches first sensor it is sensed by it and displayed. When water reaches second sensor it provides a signal to the microcontroller and it opens the dam gate partially. As soon as the water level reaches the third sensor, it signals the microcontroller and the microcontroller then signals the motor to run, which is demonstrated as opening the dam gate fully. Thus our proposed system allows for automatic dam gate opening based on water level sensing.

Mechanical locks as well as electrical locks are exposed and can be broken by robbers. We here need a lock that is not exposed on outside but can lock a door from the inside. Now this lock can be still be opened by authorized user and not anyone else. Now this allows for a remotely operated secure door opening system that can be used for domestic as well as commercial usage. The proposed system puts forward a secure door opener system that can be used for a variety of purposes. We operate a lock that is locked on the inside through rf signals. Only a specified encrypted rf signal is needed to open the door. The receiver unlocks the door only when it receives specified encoded signal. We here use rf module along with microcontroller to demonstrate the system working.
Billing System Based On RFID
We usually come across areas where barcodes are used for product identification and billing. But these tags need to be visible and sometimes need double scanning. Also these cannot be used for card scanning. Here we propose a rfid based billing system. RFID tags are easy to scan. They are detected by scanner even if they are covered by something. They also avoid product theft since they can be detected at the facility gates. Our system proposes an Rfid based billing system where we use rfid technology for product billing purpose. Our reader gathers the id and sends it to microcontroller for processing, it is displayed on an LCD display. This data can now be passed on to the computer for further billing and procedure.

Our system uses an Rf receiver circuit in order to track user. The user may carry the circuit with him. It then consists of RF transmitters placed at various locations across the park. These transmitters constantly emit rf signals. When the rf receiver circuit carried by user comes in range on an rf receiver it detects that the user is in range of that particular rf transmitter. This signals it to display the location of the user. Each location area is identified uniquely by an rf transmitter. When user enters the area the circuit reads the transmitter code and displays the location on an LCD screen.

Automated RF plus IR Based Paid Parking Manager System
Current parking systems are all manually operated systems with personnel deployed to handle the parking process. Here we propose a fully automated parking management system. Here we use a combination of IR and RF technology in order to provide an advanced fully automated parking management system. The system keeps track of vehicles entering and exiting the system. Also keeps track of the balance amount of the vehicle, deducts a particular amount when vehicle enters the parking premises. Our system first takes user id through his rf notification. It then tallies the rf code to check for user balance in account. If user has sufficient balance then the system waits for him to arrive at the parking gate. The gate uses IR sensors to detect a car arrival. Once the IR sensor pair detects it gives an intimation to the system that the vehicle has arrived. The system then deducts balance from that particular account and increments the number of vehicles entered in the facility. It does not open the gate if user has insufficient balance. The system also continuously scans for number of vehicle exiting the gate through exit gate. An IR sensor pair at the exit gate is used for this purpose. When the sensor detects a car at exit gate it signals the system to decrease the count of parked vehicles by one. Thus we provide a fully automated parking management system that successfully parking space along with account balance management with ease.

FingerPrint Voting System
One of the major factors to be taken care of in a voting process is
authentication and authorization of voters. Many conditions need to be
checked to ensure these factors. Major conditions include:
1. Check authenticity of voter
2. Authorize legitimate voters to vote
3. Avoid double vote casting by any individual
Checking if all these conditions manually is a very complicated and
exhausting task with many chances of human error. To avoid this we here
propose a fingerprint based voting system project. We use a fingerprint
module interfaced with microcontroller and an LCD screen in this system.
The fingerprint module is used to sense fingerprints and provide to
microcontroller for further processing. The system has list of eligible
voters in it, the voting system tallies the recognized finger print
against the ones stored in database. If match is found that person is
allowed to vote. Once a vote is casted by that person his id is rolled
out for that voting process. This avoids double vote casting. Thus our
system provides for a fully automated voting system with finger print
based authentication.

Wireless Red Signal Alerting For Trains
| Indian Railway network is
one of the biggest rail networks in the world. Handling and managing
such a vast network is not an easy task. The rail network consists of a
lot of junctions and vast amount of signals on set distances to manage
the train flow. Well the train driver needs to constantly check for any
red signals on every post and decide whether to stop or move forward. It
is very difficult to constantly keep track of every visual signal for
the driver. So here we propose an automatic alerting system that alerts
the driver of any red signal ahead. Our system works on the basis of Rf
technology. Whenever a signal turns red, it sets on an rf transmitter
fitted in it. The transmitter constantly transmits rf signals informing
about a red signal. Now every train needs an receiver circuit on it. The
receiver circuit when comes within certain range of the rf transmitter,
it receives the input and sends it to the microcontroller. The
microcontroller then processes this data in order to alert the driver
about the signal ahead.

GSM based Industry Protection System
With heavy automation taking place these days, the number of industries as well as number of accidents in those industries have increased substantially. Human errors and manual safety systems lead to increase in industrial accidents. So here we propose a gsm based industrial protection system that detects smoke, temperature as well as light to keep track of accidents. The system needs to detect if the temperature of a machine or environment goes above a certain level, if it goes above a level, it is an indication of a malfunction. So here we use temperature sensor to detect a possible accident. Next indication is the malfunction or overloading of machines leading to smoke. We use smoke detectors to detect smoke and similarly a light sensor to detect light due to spark or any flash caused due to malfunctions. All these indicators/sensors constantly provide their input to the microcontroller connected to them. The microcontroller constantly processes this data. On encountering a warning signal from any of these sensors the microcontroller now communicates this data to a gsm modem interfaced to it and sends out an SMS message to intended user as a warning.

As the user sends commands through RF remote using the push buttons on the remote, these commands are then sent to the receiver. The receiver then sends these commands to microcontroller which processes these commands which determines in which direction the vehicle moves. The RF remote has 4 push buttons for forward, backward, left and right which will make the vehicle move in the direction specified.

device.
The android device may be any android based phone or tab having an
android OS. The app also provides an effective GUI for providing this
functionality.
An 8051 microcontroller is used in this system. The Bluetooth receiver
is interfaced with microcontroller in order to accept the commands and
then react accordingly. It operates the loads through a set of relays
using a relay driver IC. Relays are used between loads and the control
unit.
This system proves to be very beneficial for controlling various
domestic applications and in industrial setups. The power supply setup
of the system contains a step down transformer of 230/12V, used to step
down the voltage to 12VAC. To convert it to DC, a bridge rectifier is
used. In order to remove the ripples, a capacitive filter is used and it
makes use of 7805 voltage regulator to regulate it to +5V that will be
needed for microcontroller and other components operation.

Android Controlled Automobile
An Android controlled automobile project that allows user to control a battery powered automobile wirelessly through an android application. The system uses a bluetooth modem as a medium to transmit signals between the android based phone and automobile. The android application provides a gui to the user. The commands sent through gui are sent in the form of string variables by the android application through an active bluetooth connection. These string variables are then received by bluetooth modem and then forwarded to the Microcontroller. The microcontroller now processes the data sent by bluetooth modem and checks for user commands. On recognizing direction commands sent by user(Forward|Backward|Left|Right), the microcontroller sends signals to appropriate driver IC’s. The driver IC’s now operate motors to achieve the desired movement of the automobile as sent by microcontroller. This process is continuously repeated by the system to achieve appropriate vehicle movement as per user commands through the android application.

Vehicle Theft Detection/Notification With Remote Engine Locking
The main purpose of this project is to prevent vehicle theft. This
functionality is achieved by detecting vehicle status in theft mode and
by sending an SMS which is generated automatically. This SMS is then
sent to the owner of the vehicle. The owner can then send back the SMS
tin order to disable the ignition of the vehicle. Thus in this way
crimes can be reduced to a great extent as vehicles today are being
stolen in large number. Hence, vehicles today require high security
which can be achieved with the help of this application. How the system
works is when a person tries to steal the vehicle, the microcontroller
is interrupted and the command is sent to the GSM modem to send SMS. On
the receipt of the message, the owner sends back the SMS to the GSM
modem. This is done in order to stop the engine. This GSM modem is
interfaced to the microcontroller. This microcontroller on the receipt
of the message uses a mechanism that helps to stop the engine. Motor is
being used in this project in order to indicate vehicle ON/OFF state.
Further enhancement can be done to this project by using a GPS system
that helps to find out the exact position of the vehicle with the help
of its latitude and longitude which then can be sent to the owner of the
vehicle via SMS. This data can be then entered by the owner on Google
map to find out the exact location of the vehicle.

Automated Visitor Counter With 7 Segment Display
The system is designed for optimum energy usage and is very beneficial
in case if we want to count the number of people going to attend a
particular event or any function thereby helps in collecting data by
counting the number of people.This is done by simply incrementing the
counter.
The system uses InfraRed Sensor pairs in order to fulfil this purpose
and thus saves a large amount of energy. Each pair consists of 2 sensor
pairs placed at a certain distance from one another in the opposite
direction. The IR transmitter is used to transmit IR rays straight to
the receiver which receives the input and feeds this to an 8051
Microcontroller.
As soon as a person enters the area where the system is placed, it is
detected by the IR sensor module and this info is fed to the
microcontroller. The microcontroller process this input received. At
this time the system also counts the number of people present and
increments a counter on each arrival, this count is displayed on a 7
segment display.

GSM based Industry Protection System
With heavy automation taking place these days, the number of industries as well as number of accidents in those industries have increased substantially. Human errors and manual safety systems lead to increase in industrial accidents. So here we propose a gsm based industrial protection system that detects smoke, temperature as well as light to keep track of accidents. The system needs to detect if the temperature of a machine or environment goes above a certain level, if it goes above a level, it is an indication of a malfunction. So here we use temperature sensor to detect a possible accident. Next indication is the malfunction or overloading of machines leading to smoke. We use smoke detectors to detect smoke and similarly a light sensor to detect light due to spark or any flash caused due to malfunctions. All these indicators/sensors constantly provide their input to the microcontroller connected to them. The microcontroller constantly processes this data. On encountering a warning signal from any of these sensors the microcontroller now communicates this data to a gsm modem interfaced to it and sends out an SMS message to intended user as a warning.

Rf Controlled Spy Robot With Night Vision Camera
This system uses RF remote controlled vehicle which has a camera that will be needed for spying purposes. The system proves to be very beneficial in places where humans cannot be sent for spying purposes such as military places as there can be some risk involved. The vehicle in this system has a night vision enabled camera. This vehicle can be operated wirelessly using RF remote. Here the camera send signals to the receiver used and the place that will be captured by the camera can be displayed remotely on a PC and can be recorded for further reference. In this system we use 8051 microcontroller in order to control the system which will be interfaced to the receiver. In this both the RF remote and the vehicle is battery powered. As the user sends commands through RF remote using the push buttons on the remote, these commands are then sent to the receiver. The receiver then sends these commands to microcontroller which processes these commands which determines in which direction the vehicle moves. The RF remote has 4 push buttons for forward, backward, left and right which will make the vehicle move in the direction specified.

Home And Industrial Safety Using Fire And Gas Detection System
Gas leakages and fire outbreaks in industries as well as houses have lead to wide destruction and losses in the past. Gas leakages and fire outbreaks both spread widely and lead to even greater loss of life and property if proper action is not taken on time. So here we propose a system that detects gas as well as fire outbreaks and alert us accordingly so that proper action may be taken to control it. For this we system we use a gas sensor along with a temperature sensor interfaced to the microcontroller. The microcontroller is also in turn connected to an LCD screen and a buzzer to show the alerting part. As soon as a fire starts the rise in temperature is recorded by out temperature sensor. When temperature rises beyond a certain limit it sends a signal to the microcontroller the microcontroller processes the signal and displays the fire alert status on LCD screen and also sounds the buzzer. Now the gas monitor too constantly monitors for any gas leakage. As soon as any gas is detected at the sensor it sends a signal to the microcontroller. The microcontroller now processes this data and sounds the buzzer and also displays the gas alert message on the LCD screen.'
