Temperature Controlled Fan Using Micro Controller

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.

Electronic Voting Machine Project

Electronic Voting Machine Project is a alternative method for ballet voting system which works on micro controller. In regular voting procedure there are chances of rigging but by using this method we can reduce rigging problems. One of the other features of electronic voting machine includes punch cards, voting system works on optical scanning and kiosks.

Using this system voting time can be reduced and speed up counting procedure. When punch cards was first introduced. In this procedure optical scanners are used to count a voters mark on ballot. DRE voting machine will collect voter’s information in a single machine.

Projects which work on same principle are electronic voting system. Students for refer for project report.

Hardware used in this project.

  1. KeyPad
  2. Regulated Power Supply
  3. P89C51 Micro Controller
  4. Buzzer
  5. LCD Display.

Development of Fire Fighting Robot for Fire Accident Rescue

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.

REFERENCE: The 8051 micro controller and embedded systems by Mazidi.

Wireless Stepper Motor Control Using RF Communication

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

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.

Controlling Power Grid System Using GSM Wireless Communication

Power Grid Control System Using GSM Modem Projects works on GSM wireless technology and 8051 micro controller. This application works for seven power grids. This system works by sending message to the GSM modem and it will communicate with MCU which will check is the number whether it is authorized or not and if the number is from authorized user grid control system working starts.

Grid position is calculated every moment using EEPROM which is connected to micro controller. Information is stored in EEPROM so even the power is lost there will be no chances of losing data. This system is attached to a key pad which will work as a keyboard for modifying and deleting mobile numbers. Information is displayed on 16×2 LCD screen. Load controller and Triac drivers are used in this project.

Ac Motor Speed Control Using Power Triac with Display Unit

In this application we are developing a electronic equipment for AC Motor Speed Control Using Power Triac With Display Unit. Using this application it will be easy to control Speed of AC Motor switches. In this project we use array of switches for controlling motors. Each switch has its own functionality for controlling motors at different speeds. By using these switches variations of motor speed can be managed.

Basically AC motors need more current which is not provided by micro controller used in this project. So we use TRIAC driver for our driving AC Motor. Here we need to consider two factors , Firstly driving AC motor with low current and protecting micro controller from high current. In order to solve this problem here we are using MOC 3021. A 16X2 LCD for displaying the running motor speed.

Pc Based Substation Monitoring and Control System

PC Based Substation Monitoring And Control System Project explains about a system through which power efficiency can be increased with better decision system. This system is used by most of the electricity board around the country. Along with decision making this system will bring intangibles like safety to the system. Though there are many applications which is used for improving increasing power efficiency, but they are not as accurate as that of this application. This application had created a standard by providing customizability and availability of local technical support.

Using this application it will be easy for substations to monitor different parameters like voltage, current and temperature using various sensors and these readings are sent to micro controller through ADC. By analyzing these parameters regularly system will take decisions like shut down substations. This information will be sent to PC’s Hyper terminal using RS232 cable.
