The main feature of the smart helmet is the custom built intercom set that helps in getting the riders connected with their cell phones without interrupting their journey and get fast access to the features like calling , navigation and GOOGLE engine to surf music. The Smart Helmet also provides a feature to give the riders adequate amount of visibility during their ride at night .Also provides safety feature of getting the alcohol detection unit to detect the alcohol content in the rider. 1 INTRODUCTION The use of technology is indulged everywhere nowadays in the world to ease the way of living our lives. The use of technology in different sectors of department has already started revolutionizing the world, so why not to use the technology to enhance the world of motorcyclists. According to the Global Status report, one fourth of the people dying every year are motorcyclists. One of the major reasons of this is the lack of visibility of the riders on the road and due to the usage of mobile phone while riding. The IOT has already made the communication between the devices very easy and robust. The IOT has already taken part in changing the world of home ecosystem, Grid systems, and even changing the whole scenario of the cities by building a smart city eco system. The IOT helps in gathering the large amount of data in real time and helps in establishing the connection between the devices in hassle free manner with wireless communication methodology. 1.1 LITERATURE SURVEY A lot of companies are there that are working on the smart helmet system. Smart helmets are very much user friendly in nature along with being autonomous that helps in coordination of rider with the devices in a friendly manner. The inner shell of the smart helmets becomes tough and rigid during the accidental situations and hence there is need to send the emergency message to the parents, friends and close ones to the rider. The smart helmet also provides various features like monitoring the live traffic , analyzing the rider ‘s health situation, monitoring the heart rate and many other. Now to increase the use of smart helmet in the future there is need of increasing the production quality and reduce the per helmet cost of the system. 1.2 DEVICES USED FOR SMART HELMET: Arduino Microcontroller ,16*2 LCD HT12E Encoder, HT12D Decoder, RF Transmitter & receiver, L293D Motor Driver, MQ-12 Alcohol Sensor, Limit switch, DC Gear Motor, 5V Regulated Power Supply ,12V Adapter, Bluetooth HC06 module.
