3. A smart helmet is a type of protective headgear used by
the rider which makes bike driving safer than before. The
main purpose of this helmet is to provide safety for the
rider. It is compulsory to wear the helmet, without which the
ignition switch cannot turn ON. An RF Module can be used
as wireless link for communication between transmitter and
receiver.
ABSTRACT

4. INTRODUCTION
 Transportation industry was always an essential part of the economy, and a
tool used by the government.
 Motorcycles are the craziest vehicle in the young generation and as well as to
the world.
 With the help of new technologies such as IoT, We make it mandatory for the
bike rider to wear a helmet during his/her ride. In a recent survey, every hour
4 people die in road accidents, 70% due to not wearing a helmet ,Which is the
main reason for brain damage and this leads to immediate death .
 If the rider wears the helmet, 80% chances for avoiding head injuries and we
can save a life from accidents

5. EXISTING
 There are currently two products in the market
Altor :
 It is a company which manufactures smart helmets ,
 The features of smart helmets manufactured by Altor are Bluetooth calling, Navigation, Emergency
SOS , playing songs and accident alert system
 Sena intercom:
 Sena is a US based company which manufactures smart helmets and smart helmet gears Sena intercom
is a device which can be installed to a helmet to make it smart, The functions of sena intercom
are Bluetooth calling, Navigation, playing songs .
 But both of them doesn't have any specification that makes helmet necessary to ride bike

6. DRAWBACKSOFEXISTINGSYSTEM
The existing smart helmets doesn’t have any feature to make them
manditory to wear it
And many normal helmets doesn’t have any smart features like
Bluetooth enabled calling and navigation
Because of this many people are not willing to wear helmets
resulting in the death of many bikers
As there are many drawbacks in the existing system we are proposing
a new system

7. PROPOSEDSYSTEM
We are developing a smart helmet using the internet of things (IoT) technology,
in which we ensure the safety of the bike rider and also very functional
We are using transmitter and receiver to ensure that biker wears helmet if
bikers removes the helmet then ignition will turn off
And by using bluetooth module we are able to pickup the call and we can get
the directions using navigation
By these things we can make helmets not a choice but a nessacity

8. ADVANTAGESOFPROPOSEDSYSTEM
By using this system we can reduce the number of deaths caused by
not wearing helmet
We can easily answer the important calls while driving without much
effort
We can get the directions to reach specific place which is very
important when we are new to a specific place
We can ensure the safety of biker while making it easy to get
directions and answer the calls

9. HARDWARE
REQUIREMENTS

10. HELMETSECTION
• IR Sensor:
• An infrared proximity sensor or IR Sensor is an electronic device that emits infrared
lights to sense some aspect of the surroundings and can be employed to detect the
motion of an object. As this is a passive sensor, it can only measure infrared radiation. This
sensor is very common in the electronic industry and if you’ve ever tried to design an
obstacle avoidance robot or any other proximity detection-based system, chances are you
already know about this module, and if you don’t, then follow this article as here we will
discuss everything about it.

 RF transmitter (434-Mhz):
 RF modules are 434 MHz transmitter and receiver components. RF transmitter is the
wireless data transmitting device. It transmits serial data to the receiver through an
antenna which is connected to the 4th pin of the transmitter. It transmits the helmet data
to the bike receiver through the radio frequency signals and microcontroller will process
the received data.

11. 9VBattery :
 Battery is used to power the Arduino and Bluetooth speakers.
 Switch (ON/OFF button) :
 A switch is an electric mechanism for ON/OFF the device, it is used to regulate the flow of electricity
by interrupting or diverting the current from one conductor to another. This switch is placed inside
on top of the helmet and it is pressed when the rider wears the helmet and it released when helmet
takes off. Based on the switch condition the bike ignition key will be ON/OFF.

12. 7085 VOLTAGE REGULTOR :
A 9v to 5v voltage regulator can be implemented with an LM7805 step-down voltage
converter. It is used for (10mA to 1 Amp and more) medium to a high current
application. The unique about this circuit is its ability to provide the same output
current as applied at the input end.
JUMPER WIRES :
They are used to establish connection between components and they transfer
electric signals

13. RF receiver:
 RF receiver (434-Mhz) :
 Radio-frequency receiver is an electronic device, used to communicate
between two electronic devices which are connected wirelessly. The transmission
takes place through the radio waves which are of the form of electromagnetic
radiation. The helmet module(transmitter) output data will be received by the
vehicle module(receiver) and the process will take place by wireless technology.
 LCD (16×2) :
 LCD stands for liquid crystal display that it uses liquid crystals for operation. It is
very popular and broadly used in electronic projects as they are used for
displaying information like sensors data from the project, and commonly found in
smart-phones, televisions, computer monitors and instrument panels.
BIKE SECTION

14.  ARDINO UNO :
Arduino is the open-source platform used for building electronic projects. It consists of both
hardware circuit and software tool, and this software is used to write the code and upload into the
physical board through the cable. Arduino IDE uses the simplified version of C++, but this is one of
the easiest ways to write the code. Arduino can interact with sensors, motors, internet, smart-phone
and the TV. Arduino has varieties of boards but the UNO is one of the most popular board in the
Arduino family.
 BUZZER :
It is a electrical device that makes a buzzing noise and is used for signalling.

15. IGNITION KEY :
In this project ignition key is used to represent the ignition of a bike , It has
keys to turn on and turn off the motor
 JUMPER WIRES :
They are used to establish connection between components and they
transfer electric signals

16. CIRCUIT DIAGRAM
A circuit daigram is a graphical representation of an electrical circuit . It is also
known as an electrical daigram.

17. Block Daigram :
A block diagram is a visual representation of a system that uses simple, labeled blocks that
represent single or multiple items, entities or concepts, connected by lines to show
relationships between them.

18. Flow Daigram
Flow diagram is a collective term for a diagram representing a flow or set of dynamic relationships
in a system.

19. IMPLEMENTATION
 Here we designed a system which checks the two conditions before
the ignition of the engine. The first condition is whether the rider is
wearing a helmet or not and it is detected by a position sensor. The
second condition is if the key is on or not. If any of the two or both
conditions are violated then the bike will not start. If the rider is
wearing a helmet and the key is turned on then the ignition of the
engine starts.
 When the key is turned on then system will check whether the
helmet is worn or not , if the helmet is not worn then we will be
indicated through buzzer and once we wear helmet the buzzer stops
and engine will be on ,once we remove the helmet the engine will be
turned off

21. RESULT
 Nowadays, most cases of accidents are caused by
motorbikes. The severity of those accidents is increased
because of the absence of helmets .
 In our project, we have a tendency to develop an
electronic intelligent helmet system that efficiently
checks the wearing of helmets .
 By implementing this system a safe 2-wheeler journey is
possible which would decrease the head injuries
throughout accidents caused by the absence of a helmet
and additionally reduce the death rate due to head
injury.

22. CONCLUSION
 The designed system is highly useful to avoid accidents
which happen around the night time.
 It provides more than 70% safety for two-wheelers. It is
a fact that the implementation of the system will
increase the cost of vehicles but it is better to have
some percent safety rather than having no percentage
of safety.
 This system could be further enhanced with future
technologies to provide further safety and security to
vehicle systems.

23. Scope for Future Work:
 In future, we have planned to construct our intelligent system
at a compact size and additionally as globally acceptable to
avoid accidents because of bikes.
 Can be modified for four-wheelers.
 GPS can be used to track the location of an accident.
 Light dimmer sensors can be used to dim the light automatically
when light from other vehicles falls on it.
