Now days, there are many accidents and brutal assault activities being happen and are normally at an inclination point. The project aims in designing a smart helmet to provide safety and security using PIC microcontroller. The controlling device of the whole system is a Microcontroller. Switch, alcohol sensor, MEMS sensor, GPS, RF Transmitter, RF receiver, DC motor, ESP8266 Wi-Fi module are interfaced to the Microcontroller. Whenever the user wears the helmet, the switch detects that and then only the helmet section circuit works properly. When the alcohol sensor detects the alcohol, then the system will stop the vehicle ignition automatically. MEMS sensor is uses to detect the accident of the bike and send the blynk notification to the parents/police along with location. This system sends the accident notification to the user mobile using blynk mobile application. This system uses GPS technology to track the location of the person. To stop the vehicle automatically, the wireless communication is implemented between the helmet and the ignition part of the vehicle by using RF technology
