This is a =oice Operated 3uel Dispenser S#stem. In speech recognition using water
dispenser we used *M7??< module. In this project we will switch on mechanical
rela# using speech module which will further control the water dispenser@ pump.
In the module& we can record our +oice for different le+els. This recorded +oice links
to the code at the microcontroller. (hen one speaks Athe person whose +oice has
been recorded at the module then our recognition s#stem recogniCes the sound andaccounts it to the rela# switch on& for that particular time.
The 2roject is di+ided into three parts.

Wor'in( o$ t)e pro.ect
(hen we switch on the power suppl#& the transformer con+erts the ! into D&
with a rectifier circuit. This D suppl# is then gi+en to the /0112 Module.
The +oice then gi+en as an input to the module is fed to the microcontroller.
In this project we use I >Fc7?9' as a main processor. On pin no. ' we use
one capacitor and resistor network. Two infrared sensors are connected as a
collision sensor. These sensors are connected to the input ports. On this pin
we directl# connect a photodiode as a recei+er sensor. Infrared led is directl#
connected with the 9 +olt suppl# through '?? ohm resistor. In this controller
we use negati+e input and negati+e output circuit. Output of the
microcontroller is connected to the four different optocoupler connecti+it#.
Output of the in+erter circuit is connected to the rela# circuit. (e use the
rela# circuit to control the timing of the motor. (ith the help of dc motor
A3uel Dispenser we pump out the fuel.

! transistor is semi conductor de+ice consisting of three regions separated b# two 26
/ junctions. The three regions are Base& $mitter % ollector.
The base ma# be of /6 t#pe or 26 t#pe. The emitter and collector ha+e same
impurities but different from that of base. Thus if base is of /6 t#pe then emitter and
collector are of 26 t#pe then transistor is called 26/62 transistor and +ice +ersa
transistor is called /626/ transistor.
The base is made thin and number densit# of majorit# carriers is alwa#s less than
emitter and collector. The base pro+ides junction for proper interaction between
emitter and collector.

$lectrons are majorit# charge carriers in /6 region and in 26region& holes are the
majorit# charge carriers. Thus two t#pes of charge carriers are in+ol+ed in current
flow through /626/ or 26/62 transistor.
04 D%ODE
It is a 26t#pe region and /6t#pe region formed in the same cr#stal structure& and
hence a 26/ junction is produced. Some of the conduction electrons near the
junction diffuse in to 26t#pe semiconductor from the /6t#pe semiconductor across
the junction combing with the holes. The loss of electrons makes the /6t#pe
semiconductor positi+el# charged and hence the neutraliCation of the holes on the
other hand makes 26t#pe semiconductor negati+el# charged. This region where
positi+e and negati+e charges de+elop is called depletion region.

Soldering is the process of joining two metallic conductors the joint where two
metal conductors are to be joined or fused is heated with a de+ice called soldering
iron and then as allow of tin and lead called solder is applied which melts and
con+erse the joint. The solder cools and solidifies uickl# to ensure is good anddurable connection between the jointed metal con+erting the joint solder also present

Transformer works on the principle of mutual inductance. (e know that if two coils
or windings are placed on the core of iron& and if we pass alternating current in one
winding& back emf or induced +oltage is produced in the second winding. (e know
that alternating current alwa#s changes with the time. So if we appl# ! +oltage
across one winding& a +oltage will be induced in the other winding. Transformer
works on this same principle. It is made of two windings wound around the same
core of iron. The winding to which ! +oltage is applied is called primar# winding.
The other winding is called as secondar# winding.

Scope o$ Voice ,eco(nition System
This project has a great scope in controlling +arious de+ices. !s in this project we
are using this +oice recognition s#stem to control the fuel dispenser@pump& similarl#
it can be used to control other de+ices such as robotic arm to perform +arious kinds
of motions. It can be used in the cars or other +ehicles for the starting of the engine&
and locking the doors. It is alread# used in hi6tech buildings to control the lighting
s#stem& +entilation s#stem& air conditioning s#stem etc. Athese s#stems can be
clubbed under home automation s#stems. It can be used in s#nchroniCing with the
na+igation and entertainment s#stem of our +ehicle. =oice operated dial pads are
also being used in +arious mobile phone technologies.
It can be linked with +arious machines in order to control the feed and speed of the
machine tools. It can also be linked in agricultural applications& such as using +oice
recognition s#stem in controlling the spra#ing pump of the spra#er.
Thus it has a +er# wide scope& regarding the futuristic point of +iew.
