Smart Helmet Implementation using GSM Module

India is the second most populous country in the world, and it has a lot of young people. These days, young people like riding bikes, but because it's cool, they don't wear helmets. Because of these things, there are more and more bike crashes every day, which kill people. Head accidents kill a lot of people, but you can avoid them by wearing a helmet. More and more people are getting caught driving while drunk, which leads to crashes and deaths because of carelessness. These events led us to create a smart helmet using the Internet of Things to lower the risk of accidents and deaths. The helmet has the following features: the bike will only start if the rider wears a helmet; if the rider is too drunk, the ignition will be turned off automatically; and if an accident happens, a GSM modem will send a message to the registered contact number using a SIM card.
