Human Speed Detection Project

The main aim of this project is to detect speed of human. Thus this system proves very beneficial in areas of sports. In order o record the speed of humans, this system uses a handheld radar gun pointing towards the person of whose speed is to be detected. In case of running race, it may be required to detect speed of the participants to take the decision or for some other reason. The proposed system calculates the speed by considering the time taken parameter to travel from start to end point. For this IR transmitter and receiver are installed on either of the road side on the set points. Calculation of the time taken by the human is done by the control unit. The speed of the human is displayed on an LCD Screen.

Car Overspeeding Detection Project

Our proposed project aims to develop a system that detects cars driving at speeds over specified limit and inform concerned authorities immediately. Road accidents occurrences have increased recently so there needs to be a system that allows to detect overspeeding cars. Current speed detection systems are handheld guns held by police personnel that allow them to check car speed and then manually inform authorities about the vehicle. Whereas this proposed system does not need any human interception and records car speed as well as wirelessly informs authorities of overspeeding detections.
The system first calculates the time required by the specific car for moving from first point to the second. Based on this data it calculates the car speed. This data is gathered and then transmitted by the system wirelessly to concerned authorities at a remote location. The mechanism consists of IT transmitter- receiver pair that work in combination for vehicle detection purpose. The microcontroller is now used to process this data and calculate the time required by vehicle to travel from one point to the other. Depending upon this time it now calculates vehicle speed as well as displays this on an LCD display. The system also sends this data wirelessly. It sounds a buzzer alarm if an overspeed vehicle is detected.

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.

Multi Microcontroller Networking System

Our system aims at connecting and coordinating multiple microcontrollers in order to achieve the desired output. Modern generation automobiles widely use this technology today.
Increasing number of microcontrollers are used these days for various industrial and domestic applications. Today’s cars have a good variety and number of microcontrollers working in it.
With an increase in the number of microcontrollers it becomes important to maintain proper coordination among them. The issue with such systems is that if one MC fails it is likely to affect the working of other connected MC’s.
Our project is used to demonstrate this by making use of an RS232 based command monitoring tool. The system uses a combination of three microcontrollers for this purpose. One is used to operate the load, second one is used to display output on LCD display and the third one is used to take user input through a keypad.
The input keypad is used to input a password. The password is taken through first microcontroller, second microprocessor processes the password, if right then third one switches on the lamp else if password is wrong a buzzer is activated. Well this operation can be performed by a single microcontroller too, but our system demonstrates how multiple microcontrollers can synchronize for doing a task collectively, since in real time environments its not possible for a single microprocessor to perform all these tasks alone.
Consider a situation which requires 15 connections for a display unit from microcontroller, and 7 connections from keypad. So instead of using single microprocessor and multicore cables for kilometres we use a single cable and more microcontrollers to simplify the working and reduce costs.

He may now safely work out the repairs and may return to the substation to switch ON the circuit.
He again needs to enter the password in order to switch ON the circuit.
Since the control to switch ON/OFF the circuit lies with the lineman himself there is no chance of accidents. The system uses an 8051 microcontroller in order to tally password and a matrix keypad to take password input.
The system may be later enhanced by integrating with an EEPROM for password changing as and when needed.

Industry Power Consumption Penalty Minimization Using AFPC Unit Project

 Our project proposes to minimize the energy consumption penalty for industries by implementing the auto power factor corrector system. The power factor is also known as the ratio of real power to apparent power. It is also represented as KW/KVA, in the equation KW stands for the active or real power where as KCA stands for reactive + active or apparent power.
The power generated by inductive as well as magnetic loads in order to create a magnetic flux is known as reactive power which is a non working power. An increase in the reactive power increases the apparent power, thus decreasing the power factor. With low power factor there is an increase in the need of energy to meet industry demands, this decreases the efficiency.
Our system works by feeding the time lag between zero voltage pulse and zero current pulse produced by suitable operation amplifier circuit working in comparator mode to 2 microcontroller pins. The time lag between voltage and current is displayed on a LCD screen.
The project program controls the working and actuates required number of relays from the output that will get shunt capacitors into load circuit in order to get power factor until it reaches unity. An 8051 microcontroller fulfills this process.

Our project consists of an RFID based attendance system that allows for automatic attendance marking by using RFID tags. Every student is provided with a unique authorization tag/card that is used to record his/her attendance.
A lot of time is wasted in schools and colleges for manual attendance procedures, in such cases our system provides an instant and automated attendance marking system. Every authorized student is provided with a unique RFID tag/card with his/her details fed in it. The tag consists of a built in integrated circuit that stores this data through modulating and demodulating transmitted radio frequency signals.
The data thus stored in this card is the unique identification of that person. As soon as the card is placed in front of the RFID reader, the data in it is read and attendance for that student is registered. This is done with the help of an 8051 microcontroller interfaced with the reader.
If it is a registered student, then a confirmation is displayed on an LCD screen, else a rejection message is shown that denies the attendance.
All student attendance status can be later obtained from the system when the status button interfaced with the microcontroller is pressed. This saves a lot of time and effort in student attendance registration.

Anti Stampede Monitoring And Alarm Project

Our proposed project puts forward a system that alerts us as soon as it detects a stampeding situation in large gatherings of people.
A lot of religious places, events, rural rallies etc are prone to stampeding situations. Stampedes are common in such conditions due to over abundance of people at a time. Our system is designed to warn the people and authorities in advance before such a situation arises.
The system helps us provide an efficient framework to drive a systematic pedestrian flow prediction as well risk avoiding system in overcrowded places having a chance of stampede. This is achieved by using a good number of pressure switches which get actuated when a large number of people start gathering at a single place.
All these switches are then connected to a microcontroller of 8051 family. The microcontroller receives the input of the number of switches actuated. Depending on this input on the number of switches actuated crosses a certain limit, it sets off an alarm, alerting the authorities of a possible stampede.
This status is also displayed on an LCD display connected to the microcontroller. The system can be later improved further by interfacing it with a GSM modem that sends out an sms to required authorities.

Home Appliance Control Using Android Application Project

Our project controls electrical loads by making use of an android application. The proposed system is used to control electrical loads based on the Bluetooth input signal received from the android device. It becomes difficult to keep operating electrical switches manually each time by elderly and handicapped people.
This system solves the issue by interfacing a unit with home appliances that switches these loads based on the input received from android device.
The android device may be any android based phone or tab having an android OS. The app also provided 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 is to be used in various domestic applications controlling as well as in industrial setups. The system power supply setup contains a step down transformer of 230/12V, used to step down the voltage to 12VAC. A bridge rectifier is used in order to convert it to DC later.
A capacitive filter is then used in order to remove the ripples and then regulate it to +5V by making use of a 7805 voltage regulator, that is needed for microcontroller and other components operation.

Security Access Control Using RFID Project

Our project aims at providing a secure authentication system based on RFID tags that allow only people with authorized RFID tags to access secure area. Security is an important issue for every enterprise. It is important to protect physical as well as intellectual property protection. Due to this concern only authorized people with proper tags must be allowed to enter the premises. The tag holds an integrated circuit that is used to store, process data as well as modulate and demodulate the RF signals being transmitted. So as soon as a person brings the RFID tag/card before the reader, the card is scanned and card data is compared with registered users data. If the data matches, microcontroller turns ON the load through a relay that is switched by microcontroller output. An LCD display is used to show an “AUTHORIZED” message in case the tag matches else it shows “UNAUTHORIZED” message. A lamp is also used along with the LCD display. This system can be improved later by implementing GSM technology in it. This allows sending sms message to required person or authority as soon as an Rfid tag is scanned.

Xbee Transformer/Generator Health Monitor Project

Our proposed project aims at remotely getting the information on distribution transformers using a GSM modem or Xbee. This application requires a temperature sensor, three potential transformers along with three current transformers. They work together to monitor three parameters of a generator/transformer and send this data to remote location.
Three analog values are obtained through multiplexing in connection to a programmable 8051 family MC. It is connected through an ADC 0808 IC. All of the monitored sensor values are then sent in a sequential order according to the multiplexing frequency obtained from ADC by the microcontroller. It sends these parameters to the XBEE module that operates at 2.GHz in order to send over the data.
A microcontroller interfaced system is used as a receiver that is used to receive the real time data along with error signals transmitted for desired relay required for displaying output on an LCD display. A step down transformer (230/12V) that is used to step down the transformer voltage to 12V is used with power supply. A bridge rectifier is then used in order to convert it to DC. A 7805 voltage regulator is then used to regulate it to +5 V that is required for the MC operation.

The remote controlling application is provided through an android application. This application just any android OS based device to run on. A Bluetooth device attached to the railway gate is used to receive the Bluetooth commands. These commands are then passed on to an 8051 microcontroller which then performs the required action. On receiving opening command, it drives the motors to open the gate and closes the gate on receiving the close commands. It does this by driving the motor through a driver IC to achieve this functionality.
Moreover even the status of gate needs to be seen. So the system is also integrated with an LCD display in order to display weather the gate is open or closed.

Android Controlled Remote AC Power Control

 Our proposed project aims to have control over the Ac power applied to a load by controlling the firing angle of a thyristor. In comparison to various methods this method is quite effective to control such a power supply.
The android interface required for sending commands can be sent through any android based phone/tab or any device running on android OS. The system makes use of a waveform zero crossing point that is detected by a comparator and the output of this is fed to the comparator.
The microcontroller is programmed to delay triggering control my making use of an opto isolator interface to a pair of SCR’s. The power through the SCR’s is then applied to the load.
The project makes use of an 8051 microcontroller for the operation. The commands sent via android device are received by a Bluetooth receiver mounted on the circuit. The receiver then processes the commands and sends it to the microcontroller for further processing. A lamp is used to demonstrate as a induction motor. The lamp intensity is varied as per the commands to simulate as induction motor speed.

Android Password Based Remote Door Opener System Project

Our project aims at remote password based door opener system through an android application. The system tends to make a secure door opening mechanism such that the door only unlocks when a security personnel opens it by entering the right password through an android application.
The authorized personnel needs to be present within Bluetooth range of the door but need not open the door manually. He just needs to enter the right password through his android application in order to unlock the door. This is a useful concept in places where the security needs to open gates quite usually or need to operate a door from a vehicle without needing to get down from it.
The command sending functionality is achieved through an android application. The application provides an interactive user friendly GUI for this purpose. The android application can be operated from any device running on android OS and uses Bluetooth as a medium for sending commands.
As soon as commands are sent through the android device a Bluetooth receiver is used to receive those commands. These commands are then sent to the 8051 microcontroller. The microcontroller processes these commands and then tallies the password to check its correctness. If the right password is encountered it sends command to open the door.

The rest functionality is performed at receiving end thus maintaining confidentiality of the message.
The system is designed to be used for secret code transmissions needed in military, government or other sensitive communications. User may type his message through a computer keyboard. This is then processed by an 8051 microcontroller and delivered to the receiver end wirelessly.
This system has a secret code attached to the transmission. The message typed in by user is transmitted to the receiving end through an RF transmitter. At the receiving end the RF receiver is integrated with a code and display system. User at receiving end can only view the message if he enters the right code.
On entering the right code, the transmitted message is displayed on an LCD display.

Benefits of Meditation 

Physical Benefits of Meditation

With meditation, the physiology undergoes a change and every cell in the body is filled with more prana (energy). This results in joy, peace, enthusiasm as the level of prana in the body increases.

On a physical level, meditation:

• Lowers high blood pressure
• Lowers the levels of blood lactate, reducing anxiety attacks
• Decreases any tension-related pain, such as, tension headaches, ulcers, insomnia, muscle and joint problems
• Increases serotonin production that improves mood and behavior
• Improves the immune system
• Increases the energy level, as you gain an inner source of energy

Mental Benefits of Meditation

Meditation brings the brainwave pattern into an Alpha state that promotes healing. The mind becomes fresh, delicate and beautiful. With regular practice of meditation:

• Anxiety decreases
• Emotional stability improves
• Creativity increases
• Happiness increases
• Intuition develops
• Gain clarity and peace of mind
• Problems become smaller
• Meditation sharpens the mind by gaining focus and expands through relaxation
• A sharp mind without expansion causes tension, anger and frustration
• An expanded consciousness without sharpness can lead to lack of action/progress
• The balance of a sharp mind and an expanded consciousness brings perfection

Meditation makes you aware - that your inner attitude determines your happiness.

Other Benefits of Meditation

Emotional steadiness and harmony

It cleanses and nourishes you from within and calms you, whenever you feel overwhelmed, unstable, or emotionally shut down.

Meditation brings harmony in creation

When you meditate, you are in the space of vastness, calmness and joy and this is what you emit into the environment, bringing harmony to the Creation/planet.

Personal Transformation

Meditation can bring about a true personal transformation. As you learn more about yourself, you’ll naturally start discovering more about yourself

How To Get The Benefits

To experience the benefits of meditation, regular practice is necessary. It takes only a few minutes every day. Once imbibed into the daily routine, meditation becomes the best part of your day!
Meditation is like a seed. When you cultivate a seed with love, the more it blossoms.
Busy people from all backgrounds are grateful to pause and enjoy a refreshing few minutes of meditation each day. Dive deep into yourself and enrich your life.

 

Car Overspeeding Detection Project

Our proposed project aims to develop a system that detects cars driving at speeds over specified limit and inform concerned authorities immediately. Road accidents occurrences have increased recently so there needs to be a system that allows to detect overspeeding cars. Current speed detection systems are handheld guns held by police personnel that allow them to check car speed and then manually inform authorities about the vehicle. Whereas this proposed system does not need any human interception and records car speed as well as wirelessly informs authorities of overspeeding detections.
The system first calculates the time required by the specific car for moving from first point to the second. Based on this data it calculates the car speed. This data is gathered and then transmitted by the system wirelessly to concerned authorities at a remote location. The mechanism consists of IT transmitter- receiver pair that work in combination for vehicle detection purpose. The microcontroller is now used to process this data and calculate the time required by vehicle to travel from one point to the other. Depending upon this time it now calculates vehicle speed as well as displays this on an LCD display. The system also sends this data wirelessly. It sounds a buzzer alarm if an overspeed vehicle is detected.
