ABSTRACT This project work deals with the use of Direction/Location Display which is capable of detecting intrusion at any location, sound and alarm and display the exact location of the intruder using seven segment displays. This project work is realized using top down methodology with active and passive components available in the local market. It is realized in different modules, all combined to form one function unit. The inputs are ...

ABSTRACT The ease of cutting and sealing a polythene material especially during mass production of polythene bags using automated machine has necessitated the need to automate the process. Manual cutting and sealing of polythene films do not only waste time, it also increases cost of production as more than required people are employed to a job that can be automated. This project deals with the construction of an automatic sealing ...

ABSTRACT This project is he design and construction of a voltage inverter system with trickle charging system. This device is design to provide power supply for the need of offices, household etc. In absence of NEPA power supply. It would also prevent harm to our appliances caused by power holding company LTD (NEPA) Random power outage .                                                                     CHAPTER ONE INTRODUCTION Inverter is an uninterrupted power supply which conversed ...

  ABSTRACT The robot control using an RF module is simply a robotic system whose control and functioning is achieved by the use of a radio frequency based remote. This project implements the principle of artificial intelligence to develop a mobile robot that is controlled using the hand held remote device controlled from a distance away from the robots position. The project is implemented with 8051 microcontroller which forms the ...

ABSTRACT This project deals on the design and construction of an intruder detector for home and office use. Security as one of the biggest issues in our world today and we need a system that will be able to monitor our home, offices and industries by using two sensing circuits, touch and motion sensors. These sensors will cheek for an intruder in two different positions or location and with an ...

PREFACE  The purpose of this text is to present at a primary and intermediate level a comprehensive over view of the construction principle and indeed the operation of a Digital Incubator.  We want to present a situation where by as the temperature in going up let the resistance be decreasing and as the temperature decreases let the resistance be going up. The history and importance of Electronics as a unique ...

ABSTRACT The design and construction of s refrigerating unit is handled from the knowledge of the working principles of laws of thermodynamics. The size of the containing vessel i.e the case as established to be of 45cm by 32 cm in dimension. The Angle iron mild steel to used in the fabrication and welding. The box case of two layers are fabricated. Plastic (cooler) box is then  placed inside the ...

ABSTRACT  This research work is concerned with the analysis of laboratory test results and its scientific importance. The study revealed that by analyzing the laboratory test results, the mortality rate can be reduced. From statistical observations obtained from World Health Organization, report, millions of people die from diseases like the highest being HIV/AIDS others are malaria, tuberculosis and diarrhea dating from 2001-2005. The situation can b controlled if laboratory test ...

CHAPTER ONE 1.0  INTRODUCTION A transformer is a magnetically coupled coil used in transmission of an electric power. This coil may be electrically link, but not electrically linked as in two winding transformer. It consists of primary winding and secondary winding which the number of turns varies depending on the type of transformer. Transformers are operated by the principle of mutual inductance between two separate coils wound on the same core. ...

CHAPTER ONE 1.0       INTRODUCTION    The importance of light to every mankind cannot be over emphasized, even when the earth was created; the earth was illuminated with light which makes it a place of living. This means, without light, the whole world is in darkness and as a result of this, living things be it plants, animals or human beings cannot exist. When talking about lighting, it comes from two different ...

CHAPTER ONE 1.1   Introduction Given the current energy crisis and increasing need for sustainable energy. I endeavor to create a cost effective, small-scale electrical generator which could be used to power consumer electronics. Solar energy has proven its worth as an alternative energy source because it is low-impact and emission free. It has been implemented with much success for power grids with hundreds of acres of enormous solar concentrations. In the ...

CHAPTER ONE INTRODUCTION 1.1   BACKGROUND INFORMATION As the world becomes concerned with conserving electric power and the fuels that generate electricity, there is a growing need for the conscientious homeowner to keep an eye on and minimize their power usage. Vampire or standby power is loosely defined as the “electrical power consumed by appliances while they are switched off (but are designed to draw some power) or in a ...

CHAPTER ONE INTRODUCTION  The world as it stands now can be said to be digitalised in every ramification and as such this project is aimed at looking for the way to change the way the time of the day is computed and displayed to the end user. In this method a microcontroller PIC16F877A is being used and this will calculated the time based on the number of the internal instruction ...

CHAPTER ONE INTRODUCTION 1.1   BACKGROUND OF STUDY Liquefied petroleum gas (LPG) detection is very important because gas is not only an explosive but also acts as asphyxiant. It can therefore cause serious harm to your health, your family health and homes. Liquefied petroleum gas detection was pioneered in the twentieth century by coal miners who used canary birds that would pass out if there were any spike in the amount ...

CHAPTER ONE   INTRODUCTION Water is an indispensable and inevitable substance to all living things due to its usability and high priority among other substance and materials. Provision of large volume of waters essential due to its significant purpose, which therefore called for a means by which sufficient, and good quality water can be obtained. There are different types of water namely; well water, pipe-borne waters, rain water, stream water, river ...

CHAPTER ONE INTRODUCTION   1.1   OBJECTIVE OF PROJECT   The need for a remote control alert system that can control domestic appliances and various lighting points and sockets has often been a concern for users. At times users find it inconvenient and time consuming to go around turning their appliances on or off each time there is power outage or each time they are leaving the house for work. It has also often ...
