The main aim of “smart helmet 2.0” is the accident detection and messaging system. Once the person is met with an accident, the sensor attached to the helmet senses the vibration. The location tracked by the GPS attached to it is popped to the contact numbers’ of the near by clinics and ambulances. On seeing the popped location, the nearest ambulance rushes to the location and gets the victim hospitalized in a short period of time. Thus it saves the loss of life.
