AUTOMATIC LPG GAS SENSING WITH ALARM
The project deals with the design of an automatic LPG gas sensor,
which can detect the liquefied petroleum gas. The project has been designedusing the micro controller. The project has its own accuracy and has its
timing control. We can implement this project in home, industries, hotels,
where the need to protect the gas exposure. n future we can automatically
open fire extinguisher. When the lea!age of gas automatically an alarm will
be acti"ated.

MICRO CONTROLLER BASED VOTING MACHINE
This project is the best solution to a"oid the fa!e "otes and in "alid"otes registered by our citi0ens. The project has been designed using a micro
controller 12c34. The memory is a"ailable we can ha"e many number of
candidates and that will reduce the manual counting of "otes at any time we
can !now the result within few minutes of the completion of the "oting
process. n future we may do it as a wireless module also.

FASTEST FINGER IDENTIFICATION USING 89C51
n qui0 programs and other specific e"ents we need to !now the time
of the particular e"ent "ery precisely, but this can not be achie"ed in realtime because the pressing actions will ha"e the delay in the order of few
milli seconds with normal switch arrangement and by using gate logics.
-ence we use micro controller 12c34 to sense the press action and acti"ate
the bu00er only for the concerned pressed person indicating that he has
pressed the switch.

EFFICIENT TRAFFIC LIGHT CONTROL USING 89C51
The aim of the project is to first sense the traffic density and based on
that we control the traffic. This completely replaces the con"entional traffic
light control system. ecause the time delay for each direction is fixed innormally a"ailable traffic control systems. There is no option in the circuit to
increase the time delay based on the traffic conditions. ut in our project we
sense the amount of traffic and accordingly we proceed further to clear the
traffic.

EMBEDDED LASER BASED SECURITY SYSTEM.
&ecurity is a major aspect in offices and control rooms. *ot enter into
these restricted areas. /lso documents and other important files should be
protected from fire and illegal users. hence it is necessary to pro"ide a
security system in such places for safety purpose. #ur project aims at
pro"iding such a security system. The circuit consist of fire, heat, door open
8 loc!ed open sense circuit. The heat sensing circuit is sensed by thermister.When e"er heat is sensed the alarm is acti"ated. The entering of un!nown
person is sensed by the door open with the help of limit switch. the fire is
sensed by the L+% . these all other sensed out puts are input to the
microcontroller and acti"ate the bu00er. The security of the office is ensured.

EMBEDDED DOWN COUNTER AND UP COUNTER.
The project deals with the design of an automatic counter which can
count both upwards and downwards. The project has been designed using
the micro controller. The project has its own accuracy and has its timing
control i.e. the counter can count based on the different timing delays if we
change the program. /lso this project has the ad"antage of stopping the
count at any moment. When the user wants to count in the re"erse direction
simply he has to press the switch placed in the hardware in order to get the
required output.

continually emit electro magnetic radiations, which will be identified by the
recei"er unit interfaced with a computer. The interface chec!s the status of

a"alaible. We ha"e designed an acti"e %: + tag, which has got a source by
itself generated from a regulator ).
/nd also we are registering the attendance in the micro controller also
because for uneducated peoples whom cannot to operate the computer and
not only for them we can se the attendance in the micro controller itself.

The project deals with the design of an equipment to read theenergy consumed in particular load through an analog energymeter and to cut off the total power supplied to a particular load on
prepay basis. ecause if we !now the importance and the cost ofenergy production we will be definitely be aware of consuming
power in a limited way. This prepaid scheme can be implementedin the places li!e marriage halls, lodges and hotel and e"en inoffices where the supply will be cut off based on the timing and theamount of energy consumed. The purpose of this project is toa"oid the on spot billing for power consumption and a post payscheme. &o we propose a technique to measure the same energythrough some digital techniques. The %otary arrangement of themeter is drilled at a corner of the rotating disc. Then through this

we are in a position to safeguard them through some methods. $"en the
mechanical loc! systems fail because they are easily brea!able without
ma!ing any huge noise. 5ore o"er *ow a days we need lot of security
systems in all !inds area. The security system "aries depends upon the
application Bpassword, finger and "oice etc,C &o we desire to do ta!e radio
frequency security system. The project has its own accuracy and has its
timing control i.e. based on the different timing delays which we ha"e
implemented in the mono stable multi "ibrator of the circuit. When the %:
recei"ed the door will automatically open using the micro controller.

PC BASED FRE UENCY MEASUREMENT SYSTEM
The project is actually the design of an P) based
frequency measurement equipment. -ere the circuit senses therectified out is gi"en to the comparator, the comparator is act
as a analog to digital con"erter, the digital output is gi"en to
the P) through parallel port. The program which we ha"e used
@)A language. This "ery useful in industries.

RFID BASED AUTOMATIC TRAIN STATION DISPLAY
This project deals with the design of an automatic control of a distantautomobile through o"er blue tooth communication. The project confines
itself in the control of the direction and the acceleration of the dc motor in
order to implement the robotic9based sur"eillance system. The protocol has
been designed on our own and the total operation of the "ehicle has been
controlled from the school 0one and hospital 0one.
