This document describes a smart helmet system that uses sensors and wireless communication to improve rider safety. The system detects if the rider has been in an accident using an accelerometer. It also checks if the rider has been drinking alcohol and whether they are wearing a helmet before allowing the bike to start. If an accident occurs, the helmet sends an alert message with the rider's location to registered contacts using GPS and GSM. The system aims to reduce accidents by ensuring safe riding conditions and enabling faster emergency response when needed.

3. ABSTRACT
• 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 smart helmet to provide safety for
rider.This implement by using advance feature like alcohol
detection,accident identification, location tracking,fall detection.
• This makes not only smart helmet but also feature of smart bike.Its
compulsory to wear helmet,without helmet ignition switch cannot
ON.
• A RF module as wireless link which able to communicate between
transmitter and recover.
• If rider getting drunk it gets automatically ignition switch
locked,and send message automatically to their register mobile
number with their current location.
•

4. • So when accidents occurs,it will send message by GSM
to register numbers with their current location by GPS
module.
• The distinctcity utility of project is fall detection,if the
bike rider fall from bike it will send message
automatically.

5. INTRODUCTION
• The thought of developing this project comes to do some
good things towards the society. Day by day the two
wheeler accidents are increasing and leads to loss of
many lives.
• If accidents are one issue, lack of treatment in proper
time is another reason for deaths.
• In such situation, informing to ambulance or family
members through mobile to rescue him for an extent.

10. WORKING
• In this system ESP8266 wifi is used. When the system is switched on,
LED will be ON indicating that power is supplied to the circuit.
• The accelerometer is placed in the helmet such that it detects tilts of the
helmet. When the rider crashes, the helmet hits the ground and the
accelerometer detects the tilts that are created when the helmet hits the
ground and then the microcontroller detect the accident occurrence and
it will send information about the accident and location of accident
using GPS modules.
• Alcohol sensor sense the alcoholic content whether the rider drunken or
not, if he drunken bike will not start showing as alcohol detected on
android app.
• Use of pressure sensor, gives the whether the rider wear the helmet or
not. If he not wears the helmet again bike will not start and intimate to
rider to wear the helmet.

11. COMPONENTS USED
Hardware
• ESP8266 Wifi Module
• Pressure sensor
• Alcohol sensor
• Accelerometer
• GPS
• Driver Circuit
• DC Motor
Software
• IDE
• Embedded C

12. ADVANTAGES
• Detection of accident in remote area can be easily detected and
medical services provided in short time.
• Simply avoiding drunken drive by using alcohol detector, it
will reduce the probability of accidents.
• Operates on solar as well as battery supply.

13. DISADVANTAGES
• The bike will not start unless we wear the helmet.(in the case
of lost or damage)
• Cost of project is high.

14. APPLICATIONS
• It can be used in real time safety system.
• We can implement the whole circuit into small module later.
• Less power consuming safety system.
• This safety system technology can further be enhanced in car
and also by replacing the helmet with seat belt.
• Useful for school students.
• Useful for bike and scooters.
• Help to protect life in accident case.
• Number of cases of violated traffic rules can be reduced.

15. FUTURE SCOPE
• The system will ensure that the motorbike will not start unless the rider
wear a helmet and has not consumed alcohol. Hence safety of person is
ensured.
• Also GSM technology is used to inform the family members in case of an
accident. In future scope we can use GPS to send the location of accident
along with the message.
• The vehicle tracking system can be implemented. This will protect the
vehicle from theft. This can also be used to ensure that rider is not
misusing the bike.
• We can implement various bioelectric sensors on the helmet to measure the
various activity.
• We can use small camera for the recording of drivers
activity.

16. • It can be used for passing message from the one vehicle to
another vehicle by using wireless transmitter.
• We have used solar panel for helmet power supply by using
same power supply we can charge our mobile.

17. • In this project we have successfully designed a smart
helmet band using GSM and GPS technology.
• The project made compulsory of wear helmet to start the
ignition of vehicle and while riding if any sudden change
in velocity occurs then accelerometer will monitor the
change and a short message with the location of rider will
be send to the predefined number using GSM module.
• This is a situation where we found some solution to the
problem of increased death ratio caused by road accidents.
