This document proposes a project to generate electricity from speed breakers and footsteps. It would involve placing sensors on speed breakers and roads to capture the kinetic energy from passing vehicles and walking people. A prototype was built using piezo and force sensors connected to an Arduino board and LEDs. The project aims to provide a low-cost source of pollution-free electricity. It discusses components, circuit diagrams, code, and presents the project's second place win at a tech competition. The conclusion emphasizes the need for alternative energy sources like this to address future energy demands.

2. INTRODUCTION
 An energy crises may be refer to as electricity shortage and
electricity crises. An alternative energy source is required which
is cheap no natural input source is required to generate
electricity
 In this project a mechanism to generate electricity by converting
the potential energy which is generating by vehicles and man
walking on the street
 A vehicle weighing 1000 kg going on such a speed breakers
produce approximately 0.98 kilowatt power
 The number of vehicles on the road increasing rapidly and if we
convert some of the potential energy of these vehicles pass on
such speed breakers in a busy road where about 100 vehicles
pass every minute about 1 kilowatt of electricity can be produce
every single minute
 When a person walk he lose energy to the road this energy can
be tapped and converted in the usable form such as an
electrical form

8. PIEZO KNOCK SENSOR
A knock sensor is a sensor which produces a voltage in
response to some type of physical stress such as a knock or
vibration. This is why it's called a knock sensor; it detects
knocks.
This sensor can be useful when you want a circuit to be able
to respond to knocks that a user makes against them to turn
on or off some load.
For example, in the circuit we will build in this project, an
LED will light when a knock or vibration is detected.

FSRs are two-wire devices with a resistance that depends on
applied force.
FSRs are sensors that allow you to detect physical pressure,
squeezing and weight

14. WORKING OF PIEZO SENSOR
On footstep we are using Piezo sensor. For example, in
the circuit we will build in this project, an LED will light
when a knock or vibration is detected. Specifically, for
this circuit, we will connect the knock sensor and an LED
to the arduino microcontroller. When the sensor detects
a knock, the microcontroller will then turn on an LED for
5 seconds, then shut it off. Piezo sensor is placed on
garden The Piezo sensor has 2 leads, a positive lead and
a negative lead. It is a polarized electronic component, so
polarity must be observed in order for the sensor to
work correctly in a circuit. The red lead is the positive
lead and the black lead is the negative lead. The red lead
connects to analog pin A0 on the arduino board and the
black lead connects to the GND terminal on the arduino.
Positive leg of LED is connected to the 13 on the arduino
and negative leg of LED is connected to the ground and
resistance. While tapping on Piezo sensor LED will glow
which means Piezo detect vibrations and generate
electricity.

15. WORKING OF FORCE SENSOR
FSRs are two-wire devices with a resistance that depends
on applied force. FSR's are basically a resistor that
changes its resistive value (in ohms Ω) depending on how
much its pressed. Force sensor is placed on the road.
Connect the legs to the two vertical channels on the
breadboard. Right leg of FSR attach 10kohm resistor that
connect to another vertical channel. The other leg of the
resistance should is connect to the ground. In the Right
leg FSR channel, also attached a wire that connects A0
on the arduino. The other lead of force sensor is
connected by another jumper which is taking out from
the one side of the resistance. 5V is applying on the
breadboard from arduino. And also ground it from
arduino port. Another resistance (270 ohm) is connected
to the +ve leg of the LED. Ground the –ve leg of LED. Take
out one jumper from 12 port of arduino and is connected
to the resistance which is connected with LED. While
Appling force on Force sensor FSR LED will glow which
means sensor is detecting and generating electricity.

22. FUTURE
Future work would consist of a redesign of this
model to see exactly how much data we may be
missing with the assumption that we made with
low price, weight and capacity. Despite all the
assumptions, we still have realized that this
product can be very marketable and that the
demand is extremely large which means this is a
viable design that will yield a high return on an
investment

23. CONCLUSION
Energy is important part to retain the industrial
production rate and the progress of any country.
The conventional sources are reducing day by day
and by the turn of century, we have to depend
upon the non-conventional sources of energy such
as solar energy, wind energy, biogas etc. We can
also increase the growth of country by installing
speed breaker in heavy traffic roads and toll plaza.
The crises of electricity can be reducing by
applying these two techniques
