This article is written on
the project which you may take for your final year project. As the topic
of the project that is to make the system which is the phone detector
of hidden active cell phones is very interesting. We can also explore on
it. We can get so much information for this topic. As you can easily
make this topic as your MS thesis. Basically in this project our main
purpose is to make the system which is the phone detector of hi
dden
active cell phones. In this project our main aim is the sensing of the
phone which is active at certain distance which is specify mostly it is
about one and half of meters which is used to prevent the usage of the
mobiles in certain places special where mobile phones are not allowed
for example in the exam hall. We can also take example of offices and
theaters or in many places where there is not allowed of mobile phones.
So at that places these systems are very useful. So whenever someone at
that place uses the mobile phone in such a way that he or she can try to
make the call or receiving and also if he sends or receive the message
then in this system buzzer produces beep so by which someone who handle
that place come to know about the mobile phone. So basically in this
system of the project we can use the detector which is RF detector which
uses the circuit of tuned LC which is formed in order to detect the
signals which are lie in the frequency range of GHz which is band usage
in the cell phones in such a way the frequency which is the transmission
one of the cell phone which can ranges from the 0.9 towards the 3 GHz.
As in it there is the use of the capacitor which forms the part of the
circuit which is the part of circuit name as LC circuit. When it can
detects then LED also blink.
As we can make this project as the
final year project. So I will described the apparatus which are required
in this project. In the project we use microcontrollers, segment
display, resistors, opto isolator, LEDs,buzzer, motor drive, slide
switches IC,resistors,capacitors,crystals, diodes, push buttons are used
in it .In this project we also use the current transformer in it. As
microcontrollers are used in this project so we should use the software
for this project. In it we use programming language of MC. We also use
another software in this project that is Keil software. As in this
project microcontrollers are also used in it. There are many
capabilities of that microcontrollers. They have internal RAM and ROM.
input and output parts with programmable pins. There are timers and
counters in it.These microcontrollers are capable of serial transfer of
data and serial communication of data. As this project has many of its
applications in many fields.
