Week 3 ( Final Year Project Briefing )


In this week,
we have Final Year Project briefing about the Final Year Project for this semester.
The marks will be collected for every week..
So, I have to completed the task for every week with updating my blog and show how the project progress to my supervisor..
From blogging, I learn the new knowledge to make the blog become more good and interesting.

Conclusions :
This month, I plan to buy some components for my project.
But I have to take a look the good sensor which is compatible with my project.
The price also will be the main factor in surveying the components later on.
I have to go to Jalan Pasar which is located many components that I have need to buy.
I will continued write the blog for the next time.

Wassalam.

WEEK 2 ( THE DESIGN AND HOW IT WORKS


The applications for the basic circuit include switching on a porch lamp at dusk, briefly sounding a buzzer when someone's shadow falls on the sensor or to switch on a lamp in a cupboard when the door is opened. With the addition of a second circuit board, there is an optional extra stage to this project, called the Differentiator. This changes the response of the trigger. Instead of being sensitive to light level, it becomes sensitive to the rate of change of light level.
this is the list of components that we need

The sensor will detect any motion and produce an output (Buzzer & L.E.D). Then, buzzer will active when detect any motion through the sensor. Reset button is used to reset the circuit.


note: next step is to find the components at Jalan Pasar

WEEK 2


INTRODUCTION MY PROJECT



My project's name is Development of Versatile Optical Trigger to Detect Shadow.
The idea of this project come when we finding the home security system.
Then, I expect this security system can reduce the problem of theft or trespass in any place.
Two circuit have been used to make this project more effective, buffer circuit and differentiator circuit.Motion sensor used to detect all suspicious.
Buzzer and LED will work to inform residents that the area was in a of careless or unsafe.
Also, there is a switch button which serves to reset circuit back to be in the clear state.

So, I will do the best and hope I can do this project successfully with my partner, Mohamad Daniel
