Ultrasonic RADAR
The objective of this assignment is to develop an Ultrasonic Radar. The radar will be able to detect objects that come within its field of “view” using a pair of 40kHz ultrasonic transducers mounted on a servo motor mechanism. A detected object’s relative position is to be displayed on the LCD. The software for this assignment is to be written in C, with the implementation via the PIC microcontroller.
The term RADAR is an acronym for Radio Detection And Ranging. A radar system sends out pulses of electromagnetic waves which will bounce off objects that are in its path and are reflected back to a waiting receiver. The time taken for the reflected portion of the wave to return can be used to calculate the distance to the object that generated the reflection. Typically a radar system will continuously rotate upon its axis in order to build up a 360 degree database of object locations that are within range. Each detected object’s position relative to the radar is identified on a two dimensional display.
TIME OPERATED SOLAR TRACKING SYSTEM
Commercial made solar trackers are a nice addition to any solar panel array. They help increase the time that panels directly face the sun and allow them to produce their maximum power. Unfortunately they can be expensive to buy. We decided to make our own solar tracker to see if we could reduce the cost. We did not want to re-invent the wheel but wanted to make it more affordable. We started out small and came up with the idea of solar tracking using time instead of using a device that would sense where the sun is and move the panels toward it.
The objective of this project is to control the position of a solar panel in accordance with the motion of sun. Brief Methodology: This project is designed with solar panels, RTC, Microcontroller, Stepper Motor and its driving circuit. In this project RTC is used to find or the location of Sun. It’s a open loop system. 1) INTRODUCTION Renewable energy is rapidly gaining importance as an energy resource as fossil fuel prices fluctuate. At the educational level, it is therefore critical for engineering and technology students to have an understanding and appreciation of the technologies associated with renewable energy.

This voltage is given to motor for desired speed.
SCADA IMPLEMENTATION FOR POWER GENERATOR PERFORMANCE AND CONDITION MONITORING SYSTEM
The last decade has seen a large-scale growth in the requirement of uninterrupted power supply for Industries, residential and commercial complexes and educational institutions. At many of these locations, standbypower is provided by diesel-generator (DG) sets. Proper control and monitoring of these DG sets is an imperative, since any interruption in the supply caused due to improper functioning of the standby-unit, would lead to a loss of productivity. In this project, the software and hardware details of a prototype SCADA based monitoring unit for a DG set is discussed.. The system has the following functionalities: Parameter monitoring and raising alarm when the DG set malfunctions.

If any of the sensors of the unit reports any abnormal value then an alarm is raised so that necessary action can be taken as soon as possible.
SCADA BASED INDUSTRIAL FLUID PARAMETER MONITORING AND CONTROL SYSTEM
In numerous industrial fields it is necessary to record the parameter variations to which a product is subjected, in cases where, depending on circumstances, one or more variations or the overstepping of predetermined temperatures could make the product unsuitable for subsequent use. Such device has many applications. One crucial application is to monitor and control a process where fluids have to be handles at certain predefined conditions like temperature and pressure control is necessary.
The project design consists of a microcontroller which is connected with a Temperature and pressure sensing devices. The data collected from the sensors are given to the signal conditioning system for proper modification of the signal so that the controller can process the data. The collected information is then passed on to the computer which will be interface to the microcontroller. If the measured parameters Goes above the set point or critical values, then proper action will be taken by the control unit.

We will focus on the modeling and stability analysis of networked control systems with time-varying delays. The need for methods for the stability analysis of networked control systems is motivated by the fact that a control system can be destabilized as a consequence of constant time-delays. According to the sensors output to the microcontroller and the microcontroller will deliver proper delay output to stepper motor. It will be in closed loop control system which senses any application device while rotating and gives perfect feedback to microcontroller and it will control the speed of motor.
APPLICATION OF SCADA IN SECURITY SYSTEMS FOR INSTRUMENT CONTROL AND MANAGEMENT
Security is something that is important every one today. Security is needed in the home, office, car and the airport. Industrial security is even more important for developing countries. It generates more revenue and employment opportunities with industrial growth. Regular security checks and unexpected inspections are an effective way to ensure security of industrial facilities and their products. If any weaknesses in that security system are found, they should be reported immediately to a locksmith and upper management.

The authorized person’s database is loaded in the computer by registering their RFID card.
POWER PLANT SCRUTINIZEING SYSTEM USING SCADA
The automatic control of the generation and the power flow is very essential for the smooth and effective operation of the multi-area interconnected power system. There are three main control objectives in a multi-area interconnected power system; first objective is that the total generation of the interconnection, as a whole must be matched moment to moment to the total prevailing customer demand. This in itself can be achieved by the self-regulating forces of the system. Second objective is that the total generation of the interconnected power system is to be allocated among the participating control areas so that each area follows its own load changes and maintains scheduled power flows over its inter-ties with neighbouring areas. This can be achieved by area regulation. The third objective is that within each control area, its share of total system generation is to be allocated among available area generating sources for optimum area economy, consistent with area security and environmental considerations.
Our project monitors the temperature, voltage and speed of the generator.
For each physical variable corresponding sensors are used, temperature sensor, speed sensor and voltage converter circuit this information are given to microcontroller via interfacing circuit. Microcontroller will capture the all the data and display all the information in LCD. At the same time if any abnormal condition arises controller will trip the power supply of the whole power plant or specific damaged place.
GSM based SCADA implementation using Microcontroller
The purpose of this project is to acquire the remote electrical parameters like Voltage, Current and Frequency and send these real time values over GSM network using GSM Modem/phone. This project is also designed to protect the electrical circuitry by operating an Electromagnetic Relay. This Relay gets activated whenever the electrical parameters exceed the predefined values. The Relay can be used to operate a Circuit Breaker to switch off the main electrical supply.
User can send commands in the form of SMS messages to read the remote electrical parameters. This system also can automatically send the real time electrical parameters periodically (based on time settings) in the form of SMS. This also can be designed to send SMS alerts whenever the Circuit Breaker trips or whenever the Voltage or Current exceeds the predefined limits.
This project makes use of an onboard computer which is commonly termed as micro controller. This onboard computer can efficiently communicate with the different sensors being used. The controller is provided with some internal memory to hold the code. This memory is used to dump some set of assembly instructions into the controller. And the functioning of the controller is dependent on these assembly instructions.

- Finger print recognition and matching with display
Biometric recognition refers to the use of physical or behavioral characteristics fingerprints, face, iris, signature, voice, etc) to determine the identity of a person. In order to use a human characteristic as a biometric identifier, it must possess some requisites such as universality, uniqueness, permanence, acceptability, among others. Due to these requirements, none of the biometric traits is considered the best. Fingerprints are the most widely used biometric identifier because almost all human beings have fingerprints. Besides, they are distinct even in identical twins and even facing temporary changes, such as scars and cuts, they will regenerate in the original pattern.
The methods based in minutiae points are considered the most popular and widely used in automatic systems for fingerprints recognition. Nevertheless, it is a common mistake to consider that automatic fingerprint recognition is a totally solved problem. The extraction of minutiae points is still a complex problem with poor quality images. Besides, another significant challenge is the matching of minutiae points when there is just a small overlap area between the template image and the query image, since there will be just a small set of minutia points in the intersection area. These scenarios, however, are becoming more and more common as the utilization of fingerprints sensors
in cellular phones, notebooks and other mobile devices is becoming more popular. Nowadays, the use of multi biometric systems is considered one of the keys to improve the accuracy of biometric systems.
- Face recognition based on edge detection algorithm with hardware interfacing
The automatic recognition of human faces presents a significant challenge to the pattern recognition research community, human faces are very similar in structure with minor differences from person to person. They are actually within one class of “human face”. Furthermore, lighting condition changes, facial expressions, and pose variations further complicate the face recognition task as one of the difficult problems in pattern analysis. This paper proposed a novel concept, “faces can be recognized using line edge detection”. A face prefiltering technique is proposed to speed up the searching process. It is a very encouraging finding that the proposed face recognition technique has performed superior to the most of the existing comparison experiments.
Computerized human face recognition has been an active research area for the last 20 years. It has many practical applications, such as bankcard identification, aces control, mug shots searching, security monitoring, and surveillance systems. Face recognition is used to identify one or more persons from still images or a video image sequence of a scene by comparing input images with faces stored in a database. It is a biometric system that employs automated methods to verity or recognize the identity of person based on his/her physiological characteristic. In general, a biometric identification system makes use of either physiological characteristics or behavior patterns to identify a person. Because of human inherent protectiveness of his/her eyes, some people are reluctant to use eye identification systems. Face recognition has the benefit of being a passive, nonintrusive system to verify personal identity in a “natural” and friendly way.
Transmit diversity generally requires more than one antenna at transmitter. However, many wireless devices are limited by size or hardware complexity to one antenna. Recently methods known as cooperative communication has been proposed that enables single antenna mobiles in a multi-user environment to share their antennas and generate a virtual multiple-antenna transmitter that allows them to achieve transmit diversity.
In this project, we designed of non-cooperative Orthogonal Frequency Division Multiplexing (OFDM) and Cooperative-OFDM communication system and comparing the performance of non-cooperative-OFDM and cooperative OFDM. Carrier frequency offset (CFO) mitigation is critical for OFDM based cooperative transmissions because even small CFO per transmitter may lead to severe performance loss, especially when the number of cooperative transmitters is large. Here, we showed that cyclic prefix (CP) can be exploited to mitigate or even remove completely the CFO.
4. Car AC control using CAN protocol
The main aim of the project is to control the AC depending on the window status and the fuel level in the car by using CAN protocol .
In this project we are using 2 CAN IC or even 3 Can IC also can be used depending on the application. These are connected to the CAN transceiver as shown in the block diagram below. The LCD, Window switch buttons and the AC main switch are connected to the NODE 1 of the network. The AC and the Fuel level sensor are connected to the NODE 2 of the network. In general, we know that the AC in the car is effective only when we close all the four windows of the car and we also know that AC consumes fuel. So this project is designed and developed to rectify such problems. The function of NODE 1 controller is to check the status of the AC main switch, window switch buttons and the fuel level in the car. If the main switch of the AC is ON, all the 4 windows of the car are closed and the fuel level is above the limit only then the AC which is connected to the NODE 2 goes ON else it is OFF and simultaneously the status of the AC, Fuel level and the windows is displayed on the LCD.
- AMD 2901 Core
The four-bit bipolar microprocessor slice is designed as a high-speed cascadable element intended for use in CPU's, peripheral controllers, programmable microprocessors and numerous other applications. The microinstruction flexibility of the AMD2901 will allow efficient emulation of almost any digital computing machine.
Most small processors today are being designed using a technique called microprogramming. In micro programmed systems a large portion of the systems control is performed by a read only memory (usually PROM) rather than large arrays of gates and flip-flops. This technique frequently reduces the package count in the controller and provides a highly ordered structure in the controller, not present when random logic is used moreover, microprogramming makes changes in the machines instruction set very simple to perform-reducing the postproduction engineering costs for the system substantially.

- Signature Verification based on global features
Biometrics is a verification system that identifies a person based on his physiological and behavioral features. Signature verification is the biometrics identification method which is legally accepted and used in many commercial fields such as e-business, access control and so on. In this project we proposed a robust offline signature verification based on global features to identify forgeries. In this model prior to extracting the features, we preprocessed the signature in the database. Preprocessing consists of normalization, noise reduction and thinning, for feature set extraction whics consist of global features such as signature height-to-width ration, height, length, black area, etc.

The master is then connected to the PIC microcontroller. In the PIC we use the C language to read the data from the micro controller while the micro controllers use either the C cross compilers or the assembly language.
9. CAN Based real time implementation in Automobile application
The main aim of the project is to design and implement the CAN protocol for automobile application.

Similarly the temperate is also displayed and when the voltage crosses the limit the same is displayed on the LCD. The s/w for the same has to be designed and developed using the program.
10. Industrial automation and monitoring system
In this industrial automation and monitoring system, all the plants furnaces and machines are fixed with sensors to capture temperature, pressure, vibration etc.
As the plants, furnaces and machines will be fixed in different places we should do a wireless network to communicate with all the sensors fixed in different plants and furnaces. For this wireless communication we use Zigbee protocol and technology to obtain a best result.
We use single board computers to collect sensor information and send to the master equipment. Master equipment is the server which monitors each plant for different parameters like temperature, pressure, vibration etc. If the received parameters are more than the allowable value then the master or server system will send command to the control equipment to control the temperature and pressure.
11. Implementing CAN/ZIGBEE GATEWAY/ROUTER for automotive applications
The main aim of the project is to implement the CAN-ZIGBEE gateway protocol. In this project we are using three PIC microcontrollers, in which two are connected to each other to the CAN bus via CAN transceivers and the other is connected wirelessly through zigbee to one of the controller.
The Node 2 and Node 3 are connected to the sensors, Node 2 is connected to the Node 1 through Zigbee, and it keeps sending the updated value of the sensors. Node 2 is acting as the Gateway controller. It converts the CAN protocol to the Zigbee protocol and sends the data to the node 1. The node 1 controls the device status accordingly and displays the value on the LCD.

This project uses Zigbee module interfaced with microcontroller. Both the device uses Zigbee module with microcontroller. Both the device will be communicating with each other (e.g: if one device sends ‘A’ then other device sends ‘B’ continuously) if this communication fails then the briefcase is out of transmission area and the buzzer starts beeping at both the ends.
- Automated place announcement system for BTS OR Rail using Infrared Rays
The main aim of this project is to make an automated place announcement system Bus or Train INFRARED SIGNALS. In general buses or in train there will be no facilities like automated place announcement system or display system, so it will be very difficult or inconvenience for the passengers those who are new to that places.
So this project is designed in such a way that, it will announce the place names automatically by sensing the infrared signals transmitted from each bus stop or the railway station. In our project the PCB and the CIRCUIT diagram is designed by using Express PCB software.
- Automated ambulance gates at hospital
Automated ambulance gate is a very useful device for the hospitals etc. This device uses infrared technology. Today infrared rays are used in many applications like infrared Communication, infrared remote control, and temperature measurement using infrared rays; infrared rays based pain killer etc.
But in this project we are concentrating on how to use the infrared rays to activate the gate and also how to encode and decode the infrared rays. The ambulance will have a device, which will be sending the encoded infrared rays continuously. On the other end the gate will have a device with the infrared decoder and the gate opening and closing mechanism controlled by the micro controller. The ambulance can transmit the infrared ray to a distance of 10 to 15 feet.
- Vehicle anti-collision using ultrasonic signals

This instrument is fixed in front side of the vehicle then the distance for applying break is set using the key pad id any vehicle comes near by this vehicle immediately the instrument will give alarm and it will sense the distance and if the distance matches with the set distance it will stop the vehicle.
- SMS based generator using start/stop system
It offers an integrated SMS alert and remote control system. This unit can be integrated into any diesel generator. The Generator can be Started or Stopped by sending an SMS to the generator from anywhere in the world. Used in conjunction with the alert you can decide when to turn on and off your generator even if you’re not at home or the office when the lights go out.
The SMS unit is mounted inside the generator housing (space permitting) and runs off the generators battery. When the generator is in automatic mode it will start-up when the power fails and in doing so sends an SMS to operators predetermined phone number.
The unique SMS Alert and command system allows users to quickly and easily control their Generator worldwide, with the knowledge that problems can be sorted out quickly and efficiently. In addition to that, the security system allows for safe and secure use without interference.
- Remote car lock using RF signal
The aim of this project is to develop a remote locking (door, ignition, steering) system for automobiles using RF signals. Nowadays some high cars only have this kind of remote lock. By using this remote we can lock all the doors, ignition and steering quickly. So we can save the time in this. And some time if we forget to lock all these things, no need of go to near the car. Just press the appropriate switch, the receiver end will do the corresponding operation. The cost of this project is less. So we can implement this project in lower end cars.
Why we choose radiofrequency technology: rfid readers do not require a direct line of sight to either active rfid tags or passive rfid tags. rfid tags can be read at much greater distances; an rfid reader can pull information from a tag at distance up to 300 feet. rfid readers can interrogate, or read, rfid tags much faster; read rates of forty or more tags per second are possible .
