ABSTRACT
This project is design and
construction of a sound detector with alarm system was done primarily to
detector sound. It can be use in industrial and domestics. It employ four
discreet stages with power supply which power the system.
The 1st block is pick up
amplifier containing the microphone and the input which serve as a transformer
which the function is to pick up the smallest sound that comes close to the
amplifier
The second block is comparator with hysterias.
The function as analogue to digital convector and also it help to accumulate
amparm sound like sound of the gun short or any other heavy sound
Block three. This is transistor
switching this stage consist three bipolar function transistor (BJI) with a
decay circuit found using capacitor time constant (T – RC) with a 12v Re let,
it output work function is to switch the alarm circuit.
Block four. This is the Alarm circuit,
it’s function is the alarm tone. It is an stable mutivibertor that produce 1kH2
tone frequencies which sound as alarm signal with loud speaker which serves as
an output transformer.

INTRODUCTION
1.1 THE
GENERAL DESCRIPTION OF PROJECT
Due
to advance electron logy in the electronic which gave rise to automation of
electronic system in domestic and industrial use. This development is what gave
me the courage to choose a project topic on sound detector with alarm system.
This system employ four discreet stages with power supply namely, the pick up
microphone, Amplifier, Schmih trigger, thysistor switch circuit with rally
circuit and 1kHz turn generator which from the alarm circuit at the input of
the system a transducer which a capacitor microphone whose the function is to
piece the sound and it out put to feed in to class. A amplifier microphone
preamplifier of two transistor stage cable of amplifier the sound to a standard
were it be accepted by the schmih trigger or built using comparator with
hysterics. This comparator with hysterics is acting as amuroge to digital
convector (AID) whose one put switching between high or low conditionally. An
interface containing a transistor switching circuit with rally at it out put
such that once a sound is pick up out the input the rally is energized capable
of switching an alarm circuit on.
1.2
OBJECTIVE DESIGN
The main objective design of the project is to
design and construct an electronically operated system capable of picking sound
of a visitor at the door processing the alarm put natural sound wave to an out
put electrical sound signal to alarm signal to alert the people inside the
house that some body is at the door
outside, also it help increasing the standard exposure in the practical aspect
of engineering training.
1.3 SIGNIFICANCE
OF THE STUDY
The
project designed work on sound detector with alarm quite, applicable in almost
every where like industries and for domestic use for instance it could serve as
audio activated door bell for office installation also used to monitor an
intruder in our domestic places.
1.4 THE
REPORT LAYOUT
For
clarity and simplicity, the report is divided into five chapters. The chapter
one deals on the introduction, which centers on general description of project,
design objectives, significance of the project and the report layout. The next
chapter which is chapter two is on the literature review which talks on the
historical background of sound detector with alarm system theories and models
relevant to the design, list and description of the system component and lastly
distinction between the existing method of design and the new approach. Chapter
three is on system design and which is all about the description of the system
building blocks, system design specification, block diagram of the system,
description of the overall operation of the system. Component list and complete
circuit diagram of a sound detector with alarm system. Chapter four is on
implementation, testing and results. Then chapter five is one cost analysis
conclusion and recommendation.
As
maximum measure of comprehensibility was ensured throughout the report. This is
indicated by the pattern of presentation and consistent system of rotation.
This I believe will ensure maximum reader satisfaction.
