FINDING THE SCOPE AND LIMITATION FOR MY PROJECTS
WEEK 9
A scope
limitation is a restriction on the applicability of an auditor's report that
may arise from the inability to obtain sufficient appropriate evidence about a
component and the system . When our
projects is unable to apply all the audit procedures that are considered
necessary, either by circumstances the audit is limited in scope.Some scope
limitations arise for reasons that are beyond the control . Basically this project is divided into two
main parts which is Hardware development which consist of the part that we can
see and touch like development of ir
sensor , development of microcontroller part with the buzzer and also LED. While the software development, are the programming
for every part. In every product they must be a limitation . Limitation can be
defined about what our products cannot
do and have a difficulities in developing it, in my projects Sometimes our IR sensor cannot detect our eye
if our eye open and close too fast and exact functionality depend on great
positioning and aiming of emitter and detector respect to eye . So to prevent
the limitation, i need to put the IR sensor at the proper place so that it can
detect in any condition . And the main problem that i can trace from my
research was, it is a very difficult work and veru difficult thing to do in
tracing our eye by using IR sensor. The IR sensor can trace but it is must be
place precisely .
RESEARCH THE AVAILABILITY & RELIABILITY OF THE PROJECTS.
WEEK 8
After doing the
research about the projects, in this week i had find the projects that have the
same concept of my projects. After that i had found the projects that same
concept like mine but it is more advance projects. So i take this projects as
my inspiration . Although the system is not same but the concept is quite the
same.
RESEARCH ABOUT SOFTWARE
WEEK 7
The previous
work is study about the main components of the system and for this week i had
make a study on software that i want to use in developing this projects. I had
make a research about the projects from the internet, books , journal and etc.
And the software that i may use is KEIL software which is microcontroller
software but i need to do more research about the projects . The introduction
about the software are The µVision IDE from Keil combines project management,
make facilities, source code editing, program debugging, and complete
simulation in one powerful environment. The µVision development platform is
easy-to-use and helping you quickly create embedded programs that work. The
µVision editor and debugger are integrated in a single application that
provides a seamless embedded project development environment.
CONTINUE RESEARCH COMPONENTS
WEEK 6
In this week , i
had make research about the other components used in my projects and for this week , i had research about the
characteristics of the components and also circuit that used.
- · IR SENSOR
- · LM 358 COMPARATOR
- · LCD
- · BUZZER
IR SENSOR
LM 358 COMPARATOR
An operational
amplifier (op-amp) is a DC-coupled high-gain electronic voltage amplifier with
a differential input and, usually, a single-ended output. In this
configuration, an op-amp produces an output potential (relative to circuit
ground) that is typically hundreds of thousands of times larger than the
potential difference between its input terminals. Op-amps are among the most
widely used electronic devices today, being used in a vast array of consumer,
industrial, and scientific devices.. Op-amps may be packaged as components, or
used as elements of more complex integrated circuits.
LCD
LCD is used to
display the driver condition. I had choose to display on LCD because of LCD
will function during day or night. So other people can still know about the
driver condition . the working of LCD are is a flat panel display, electronic
visual display, or video display that uses the light modulating properties of
liquid crystals. Liquid crystals do not emit light directly.LCDs are available
to display arbitrary images (as in a general-purpose computer display) or fixed
images which can be displayed or hidden, such as preset words, digits, and
7-segment displays as in a digital clock. They use the same basic technology,
except that arbitrary images are made up of a large number of small pixels,
while other displays have larger elements.
BUZZER
A buzzer or
beeper is an audio signalling device which may be mechanical,
electromechanical, or piezoelectric. Typical uses of buzzers and beepers
include alarm devices, timers and confirmation of user input such as a mouse
click or keystroke .
PREPARING THE SYSTEM OF EYE DETECTION AND ACCIDENT PREVENTION
WEEK 5
PREPARING THE SYSTEM OF EYE DETECTION AND ACCIDENT PREVENTION
The development of this projects are divided by 2 which is hardware part
and also software part. The above figure
is the block diagram of eye detection and accident prevention projects.The
methodology shows the process flow that will happen for this project
construction. For the first stage , the eye blink will be detect by using IR
sensor as sensor to detect eye blinking . the IR sensor are divided into 2 part
which is IR transmitter which used to
transmitted the infrared rays to our eye and the reflected ray will be
received by IR receiver. IR transmitter and IR receiver must be mounted at the
straight line to each other. This is because the further distance between
emitter and receiver will decrease the amount of infrared light hitting on
emitter. The IR sensor will be mounted at the LM358 comparator which The
comparator is constructed with LM 358 operational amplifier. In the comparator
circuit the reference voltage is given to inverting input terminal. The non
inverting input terminal is connected IR receiver. When interrupt the IR rays
between the IR transmitter and receiver, the IR receiver is not conducting. So
the comparator non inverting input terminal voltage is higher then inverting
input. Now the comparator output is in the range of +5V. This voltage is given
to microcontroller or PC and led so led
will glow. the output from the sensor
will be send to the microcontroller. If the eye is closed means the output of
IR receiver is high otherwise the IR receiver output is low. This to know the
eye is closing or opening position. If
the eye are still in ‘0’ conditions which means that the eye is still opening
the sequence will be repeated until the output of receiver is “1” , then if the
output of IR receiver is “1” the the microcontroller will send the signal to
the output ehich is indicare by the LCD which is the function is to tell the
behind people to be ware with this vehicle because the driver in the drowsiness
condition, LED will indicate the emergency lamp and the function will be
benafit to the othe vehicle and also alarm which will make sure that the driver
will wake up .

SENSOR THAT DETECT EYE BLINKING
WEEK 4:
I had made research about the sensor that need
to use to detect the eye and I had found a few type of sensor that used as
sensor to detect eye blinking and
finally I choose IR sensor because it is suitable for make prototype.
IR Sensor (IR Receiver and IR Emitter)
The
basic principle of IR sensor is based on an IR emitter and an IR receiver. IR
emitter will emit infrared continuously when power is supplied to it. On the
other hand, the IR receiver will be connected and perform the task of a voltage
divider. IR receiver can be imagined as a transistor with its base current determined by the intensity of IR light
received. The lower the intensity of IR
light cause higher resistance between collector-emitter terminals of transistor,
and limiting current from collector to
emiiter. This change of resistance will
further change the voltage at the output
of voltage divider. In others word, the greater
the intensity of IR light hitting IR receiver, the lower the resistance of IR receiver and hence the
output mvoltage of voltage divider will decreased. Usually the IR emitter and IR receiver will be mounted
side by side, pointing to a reflective
surface. The further distance away
between emitter and receiver decrease the
amount of infrared light hitting the receiver if the distance between the sensor and a reflective
surface is fixed. Since the output voltage from voltage divider
varies with the intensity of IR light,
and microcontroller is not used in this
project, a comparator (LM324) is used to show the changes. The eye-blink sensor
works by illuminating the eye and/or eyelid area with infrared light, then
monitoring the changes in the reflected light using a phototransistor and
differentiator circuit. The exact functionality depends greatly on the
positioning and aiming of the emitter and detector with respect to the eye.
WEEK 3
In final
year project (semester 1 ) ,we need to show the research progress . In unikl bmi, we
had given a choice to choose whether update the research progress in Log book
or in the blog. My adviser had asked me to create a blog to update the
progress of every meeting and all the result of my research must be updated in
this blog also. I preferred to update the progress in blog than in log book.
This is one of the way of learning process toward the excellent in future. And
we have to send our blog address to RPS bmi
and to adviser .

Accident
statistic in Malaysia
Why I choose this projects as my final year
projects. Based on the statistics above show that from day to day, week to week
, month to month and year to year , the statistics of the accident happened had
increased . By looking at the newspaper , the main problem why accident
happened because of driver become asleep after a long journey. By looking at
this problem I get an ideas in develop the projects that help driver to awake from
the sleep when they become sleepy . This will help to increase the accident
statistics in malaysia .
WEEK 1 & WEEK 2
As a one of the candidate for Final Year
Project for Semester 1,we have to choose lecturer to recommend and supervise
student .Student have to consult with the adviser time to time and report to
them the progress of the project. I had decided to choose SIR IZWAN ARIEF from electronic section to monitor me in
making final year projects . After choose
my adviser, I had met him and asking whether he agree to supervise me in making
my final year project and ALHAMDULLILAH , he agreed and he had told me make
research in project that I want to do and bring the simple proposal on the next
day to ask for his opinion. During my research , I had read an article about
the accident happened on the highway because of driver fell asleep while
driving and this article had attract me in producing something that can
decrease the accident statistic in Malaysia. After make a research and with my
trustful decision, I had decided to make "eye detection for accident
prevention". On the next day I had presented my ideas to my supervisor and
finally he approved my title. From now and the next
week , I need to research about my final
year project to get more ideas in producing this project which is my aim is to
decrease the statistics of accident happened in Malaysia.
