Σύνοψη

This project idea was created when a good friend that who studies in England
became aware that his room-mates used to enter his room while he was in classes and
were messing around with his private staff and his university notes.
Then he asked me to help him discover who from the five people that live with him in a
shared house did not respect the privacy and the request of the others in order to stop this
situation.
SOLUTION
After some thinking, the construction of a security alarm came to our minds. A
security alarm that would trace the presence of a person in the room and since I
never knew much for ultrasounds I thought it will be a good healthy challenge to try
and obtain a circuit and understand its operation and construction. There are many
other type of alarm sensors from piezoelectric to infrared.
In security alarms the most usually type of detector used is the infrared but the
ultrasonic sensor was the one I chose for my work after finding some relevant
information over the Internet.
The whole project can be used in a million ways to do virtually anything
concerning security and not only for this situation. In any kind of intrusion in small or
big houses, it can detect and intimidate the intruder or it can cause him severe health
damage. It can also be used not only in a house but due to its small size it cam be
used in a car, a shop or a specific drawer or cupboard.
The system can be "cut" individually to many other smaller independed
detectors acting each on its own.
After the method of detection was found a way to capture or photograph the intruder
was needed.
At that point Mr.Hajioannou had the idea to use a microcontroller in the project,
a thing that I though was not needed but eventually was vary helpful in the completion
of the security alarm and also gave me a good introduction in the world of
microprocessors and microcontrollers, which is essential for an electrical engineer.
The microcontroller would be responsible for the operation of a camera
installed on top of a stepper motor interfaced with the micro controller in order to
capture the person, who was responsible for the intrusion.
