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.

< Bhai Gurdas Institute of $ngineering % Technolog#


8/16

$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.
