ABSTRACT

The project work titled Design and construction of a metal detector. When fully design and implemented would be able to detect any metallic material that is passing or coming close. This function would serve as a security check for dangerous metallic material as an alarm. Going by the sophisticated means of armed rubbers adopt these days in the breaking into bank supermarkets offices and highly secured area. No security system will be optimized or complete without the installation of metal detector. This will stop or reduce to the bearest minimum the activities of men of the underworld. The device we then build we function as a metal detector that can scout out metal objects, such as coins, nails, keys such as car keys you may not be able to fine, and even gold if youâ€™re looking for it in a beach (through this one may not have industrial strenght). This metal detector can detect certain kinds of metal- especially iron â€“containing metals, which are called ferrous meat, even if under a half-inch of drywell or sand.

CHAPTER ONE
INTRODUCTION
1.1 Background of Study
It has been observed that the rapid growth in the technological knowledge across the world has been accompanied by a rapid rise in crime rate. These criminal acts takes the form of breaking of private and official homes and making away with a huge sum of money, valuable and in most cases hosts of lives. The background of this project work comes into play for the removal or minimization of the above criminal act by a way of a METAL DETECTOR, which will be handly or connected to a strategic position in our homes and offices.
Detection and clearance are still very often carried out in humanitarian demining ways using manual methods or computer as primary procedure. When operating in this way, detection phase still relies heavily on metal detectors, whereby, each alarm needs to be carefully checked until it has been fully understood or its source removed. This is normally done visually and prodding or excavating the ground. Metal detectors are probably going to remain in use for some time.
1.2 Problem Statement
Going by the sophisticated means armed robbers adopt these days in breaking into banks, super markets and highly secured areas or the activities of assassins in conference hall, airport, hospital e.g. there are every indication that they are out for the worst and a better way of lessening the harshness of these menace is to get highly alerted security wise. No security system will be optimized or complete without the installation of metal detector. This will stop or reduce barest minimum, the cases of men of the underworld breaking into banks, hotels, conference hall, homes, hospital e.t.c systematically undetected.
The exigency of Metal detector involvement in security outfits whether national, sub-national and domestic level cannot be over emphasized.
The researcher was motivated to design a project which will demonstrate the undisputable wide use of transistors in field of electronics to produce the kind of sound that should be able to alert people for special attention, and serves as a danger signal in a nutshell.
