WHY IT IS CHOOSED ?
• Most of the people in our country use helmet to avoid police fine
not because of their safety.
• To make indispensable to wear helmet for riding bike we develop
the project.
• Smart helmet ensures wearing the helmet by rider and chin strip
attachment during a ride.
6. 006
COMPONENTS USED IN OUR PROJECT
• Arduino NANO and UNO
• Alcohol sensor MQ3
• Bluetooth module HC05
• LCD display board

CHALLENGES FACED DURING PROJECT
• Programming error
• Ascii value detection
• Bluetooth communication error
• Pairing of Bluetooth module
• Mq3 proper calibration
• Too many trials
• Its Cost
12. 012
LEARNING FROM PROJECT
• Idea implementation
• Problem solving
• New software and language
• Electronics components
• Coding and programming
• Actual bike wiring and ignition system
• Teamwork and SGA
13. 013
• Real time location feedback
• SOS system by GPS / GSM module
• Charging of battery from bike
• Battery level indication of helmet
• Health monitoring
• Crash detection
• Call answering
FUTURE SCOPE
14. 014
• Bluetooth module – versatile nature
(Like our phone we can pair any two Bluetooth module with bike
Bluetooth)
• Longibity- MQ3 average life >10 yrs.
• Other components like Bluetooth module >5 yrs.
• Cost- setup cost- 3000 (during project)+ helmet
price
• If mass production considered, then <2000
