AIM:Prepaid Energy Meter Using Smart Card Projects main idea is to develop a micro controller based application which is used to pay bills using a smart card technology.

PURPOSE: This project will focus on overcoming the past procedure of electricity bill payment methods by using smart card technology. This system will provide reliability and increase security.

Description:        In present scenario electricity bill payment can be paid at e-seva or substations. This process is a time taking and risky process. Using new smart card method payment process will be fast and time saving. Electricity bill can be paid using prepaid electricity billing system. This system works on smart card technology.

Smart card is similar to that of SIM card which should be recharged same as that of mobile recharge card. Based on the usage of power we need to recharge the card by placing it in the card reader. Card reader is interfaced with the micro controller using a serial interfacing. While recharging it will ask for how much of power consumption we need to use in KWH. This information is displayed on the LCD screen.

AIM:     SCADA projects main idea is to develop a micro controller based RF system through which we can continuously monitor and organize the processes that which are running on various SCADA systems.

PURPOSE: Main purpose of using SCADA system is to increase the quality of the services and increase profit by using wireless technology like RF. Using this system it will easy to automatically collect data  and archiving systems through SCADA for reducing process cycle time.

Description:This system will be implemented in industries where there is need to monitor different processes at a same time. SCADA system will be installed in control rooms, through this system operator will monitor different process. Using this application man power will be decreased and reduce cost of the project and increase profit.

AIM:       The main aim of Gsm Based Distribution Transformer Monitoring System project is monitoring different parameters of a transformer such as voltage,current and frequency.

Description: In this paper we will explain in detail on design and implementation of cell phone embedded system though which user can monitor and record important parameters like load currents, oil in transformer and temperature variations. In this project we use GSM modem which will be connected to a standalone single micro controller and different sensors. This kit is implemented at transformer site and each parameters are monitored continuously and recorded in to s channel ADC converter. Recorded readings are stored in to memory and analyzed regularly. If there are any complicated situation arises system will send SMS to mobile phones by using GSM Modem.

Temperature Controlled Fan projects main idea is to auto adjust fan speed based on the variations on temperature inside room. Here we use LM35 sensors to read temperature and send information to micro controller after converting analog signal to digital signal using Analog to digital converter. Micro controller is connected with control relays for controlling fan speed.

User is provided with a LCD display where information is displayed. Buzzer is used as indications of changes in fan speed. 8051 micro controller is used in this project. Code is written in c language and written in to micro controller.

Fire Fighting Robot For Fire Accidents projects main idea is to develop a application which can detect unexpected fire attacks and take precaution steps to save property, human life. Fire accidents accord mainly when someone is away from house or sleeping so it will be hard to detect fire accidents. So there is need for a application which can detect fire accidents.

In this paper we will explain about prototype system which can autonomously detect and extinguish fire accidents. This application is developed using fuzzy based micro controller controlled robot.

This robot will sense the fire effected area and move through burning oil derrick and stops fire using a blower. This example will show how it works in real scenario.

In this system we are using simple 8051 micro controller, and program is written in c language and written to micro controller.

 SOFTWARE: Embedded ‘C’

 TOOLS: Small Device C Compiler & Keil uvision.

TARGET DEVICE:  AT 89s52.

APPLICATIONS: industries, chemical      laboratories, homes.

ADVANTAGES: Low cost, automated operation,     Low Power consumption.

Wireless Stepper Motor Control Using RF Communication project explains about developing a RF based wireless application through which users can control stepper motor remotely. Stepper motors are used in electronics, mechanical, chemical industries for different purposes one among them it is mostly used in robotic applications where stepper motor need to be controlled remotely. In this paper we will cover design and development feature of the wireless stepper motor system.

IR transmitter will collect switching signals at the receiver side and transmit to the receiver side. IR receiver will collect and send to micro controller by decoding the signal. Micro controller will take decision to control motor speed.

Advantages:

Remote controlled

Simple operation

Less Power Consumption. 

Scopes for Advancements:

• Range can be increased using high power RF transmitter and receiver.

Wireless DC Motor Speed And Direction Control Using IR Communication system works with few amps of current. This application uses pulse width modulator for controlling speed of the motor. This system can work on different voltages mainly 12 v and 24 v by just few minor wiring changes. Using this application we can control speed of the motor and brightness of the lamp.

 Advantages of using pulse width modulator are it will produce high torque in the motor with less supply voltage. Because of this high torque motor will overcome internal resistance more easily.

Operation of this project starts from with switching system where on transmitter site a direction control switches are used to control the motor speed on receiver side. Transmitter will send signal using IR transmitter and received by IR receiver. IR receiver will transmit signals to micro controllers which will decode information and take decisions.

Super Control And Data Acquisition System Using GSM provides solution for controlling parameters like temperature, Light, Voltage and Current by using Global position system modem by sending messages. This application works on two methods, in one method user can adjust temperature, light intensity and other parameters and in second method user can auto set the feature. Different sensors are used for calculating variations in parameters and information is displayed on LED screen for indication.

In this project, we are using four sensors, four relays, ADC (Analog to Digital Conversion), Microcontroller, LCD (Liquid Crystal Display) for displaying the messages.
