INTRODUCTION

5. As we know day by day the population is increasing, with increase in
population we need some power generation tool for the increased
population needs. To overcome this problem, we came with a solution
of generating power through human footsteps, the energy which gets
wasted in locomotion. For this purpose we use piezosensors which
converts the pressure on it to a voltage and can be used at public places
like Railway Station, Theaters, Airports, Bus Stands, etc where people
walk alot so as to conserve this natural resource and to develop charges
through human walks we use this method which generates decent
amount of charges/ powers to solve electricity problem without burning
coal which is getting less and will be found in less amount in future.
Atleast it can solve a bit of electricity crisis problem. so, that’s our
motivation to work on this project.
MOTIVATION

6. ❖ The system generates voltage using
footstep force.
❖The system serves as a medium to generate
electricity using non conventional sources
(force) and stores it.
❖This project is designed in such a way that it
is useful at public places like railway stations
where a lot of people keep walking through
all day.
OBJECTIVE

LCD Display :- DC Battery:-
COMPONENTS

8. Earlier developments in piezo electric circuitry involved concentration on
small vibrations and hence small strains. Also, few of them required
external voltage supply and there were number of losses in the system to
low voltage which amounts to low voltage output. In December 1929,
scientists in U.S Navy performed various researches on piezoelectric
crystals. Their focus was primary on the dimensions of crystals. These
crystals cut with such dimensions are effective in controlling oscillations of
a 50 watt vacuum tube. In 1985, the concept of using handwriting
dynamics for electronic identification was performed in Sandia
Laboratories. In 2000,various applications of piezoelectricity in wireless
sensing was studied and experimented.In 2005, United states Defense
Advance Research Project Agency initiated an innovative project on
Energy harvesting which attempts to power battlefield equipment by
piezoelectric generators embedded in soldier’s boots. Their mission was to
harness 1-2 watts from continuous shoe impact while walking was
abandoned due to additional energy expended by a person wearing the
shoes. The main aim is to use piezoelectric crystals in high vibration to get
satisfactory result.
Literature Review:-

9. It can solve the problem of electricity crisis, the utilization of waste energy
foot power with human motion is very important in highly populated
countries.
India and china where the roads railway stations are all full of crowds can be
benefited alot by this method of power generation.
Conventional method of power generation becoming insufficient; It
introduced a new problem, lack of power; There is a need arises for an
alternative power generation method; Energy is wasted in many forms by
walking.
PROBLEM IDENTIFICATION

10. Arduino is a popular programmable board accustomed creates
projects. It consists of an easy hardware platform also as a free source
code editor which features a ‘’one click compiles or upload’’ feature.
Arduino offers an open-source electronic prototyping platform that’s
easy to use and versatile for both the software and hardware. Arduino
is in a position to sense the environment through receiving input from
several sensors.
B. Piezo Electric Sensor : -
A piezoelectric sensor may be a device that uses the piezoelectricity
to live pressure, acceleration, strain or force by converting them
to an electrical charge. Based on piezoelectric technology various
physical quantities are often measured the foremost common
are pressure and acceleration. A piezoelectric transducer has
very high DC output impedance and may be modeled as a
proportional voltage source and filter network.
A. Arduino Uno Board:-

11. The voltage V at the source is directly proportional to the applied force, or
strain. The output is then associated with this mechanical force as if it had
skilled the equivalent circuit.
One disadvantage of piezoelectric sensors is that they can’t be used for
truly static measurements. A static force will end in a hard and fast
amount of charges on the piezoelectric material.
The most effect on piezoelectricity is that with increasing pressure loads
and temperature, the sensitivity is reduced thanks to twin- formation.
C. DC Battery:-
A battery may be a device which will store electricity.
Some are rechargeable, and some are not. They store direct
current (DC) electricity. A battery really means two or
more wet or dry cells connected serial for more voltage,
or in parallel for more current. The chemical reactions
that occur in a battery are exothermic reactions and,
thus, produce heat. For example, if you allow your laptop
on for an extended time, then touch the battery, it'll be
warm or hot. However, the batteries utilized in laptops
are called lithium-ion batteries and that

12. These components are “sophisticated” for being used in combination to
microcontrollers, which means that they cannot be activated by standard IC
circuits. They are used for writing different messages on a miniature PCB
LCD. The component chosen here is low price and great flexibility most
frequently used in all applications. It is based on the HD44780 microcontroller
(Hitachi) and can display messages in two lines with 16 characters each. It
displays all the 5x7 elements like alphabets, Greek letters, punctuation marks,
mathematical symbols .
E. GSM Technology :-
GSM (Global System for Mobile communications) is an open, digital cellular
technology used for transmitting mobile voice and data services. GSM
(Global System for Mobile communication) may be a digital mobile
phone system that's widely utilized in Europe and other parts of the
planet. GSM uses a variation of your time Division Multiple Access
(TDMA) and is that the most generally used of the three digital wireless
telephone technologies (TDMA, GSM, and CDMA). GSM digitizes and
compresses data, then sends through a specific channel with two other
streams of clients data, each in its own slot.

13. A FLOWCHART AND USES OF
ARDUINO UNO BASED FOOTSTEP
GENERATOR:-

14. The main components of the system include piezoelectric sensors, voltage
boosters, voltage Regulator, PIC Microcontroller, Battery, LCD display, LDR
and a socket for mobile charging.Here in this system,at first the output from
an array of piezoelectric sensors is fed into voltage booster. In the system,
two voltage boosters are used to boost the voltage to get the desired result.
The output is from piezoelectric sensor is in the range of 3V to 4V. It has to be
boosted to a range of 9V to 12V with the help of voltage boosters.
A constant output voltage irrespective of fluctuations will be maintained by a
volt regulator. This regulated voltage is stored in the battery and is fed to the
microcontroller.The LCD which is interfaced with the microcontroller in turn
displays the amount of charge stored by the battery. In this system the power
generated has been used for two applications such as lightening a street light
and charging a mobile phone. A LDR is used to indicate the street application.
While a buzzer is used to alert the battery when it falls down below the
charging the microcontroller.For PIC Microcontroller 5V is required by them
for working.The mobile charging socket also requires 5V for it’s operation.

the vehicles too much thus increases input torque
and ultimate output of generator, If we are used
this principle at very busy stairs place then we

purposes.
DISADVANTAGES:-

19. This process provides electricity with the assistance of electronic
components that produces application of energy using human
footsteps. The ADC converter deployed in the circuit stores the charge
for future constraints. So as to extend. The ability of the entire system
if super capacitors and converter square measure employed in place of
the conventional ones then a lot of charge will be hold on than the
standard ones. The super capacitors store and discharge energy while
not intense abundant renewable energy. Thus, the need of constant
increase of power will be met by putting in these systems in heavily
packed places.
