Now a days we see many accidents are taking place due to alcohol consumption of drivers during driving. Though it is said that alcohol consumption while driving is not suggestible and illegal people are accustomed to the habits. So here is some protection act that can be implemented to all transportation vehicles so that we can have an accident free or safe journey.
Here in this project, we use certain equipment which is controlled by the micro controller that is we use a gas sensor or alcohol sensor which senses the alcohol and as soon as the alcohol is detected the robot stops or the vehicle is stopped and sends the message i.e., GPS Data to mobile using gsm module. The micro controller is interfaced with gas sensor and 555 timer and the motors are driven using L293D and the gsm module is also interfaced with micro controller using MAX232.
The L293D driver circuit is used to drive the motors and max 232 is used as serial interface for GSM module. Power supply is provided by the 12v battery source.
This project uses regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. The programming language used for developing the software to the microcontroller is Embedded/Assembly. The AVR STUDIO is used to edit, compile and debug this program. SINAPROG programmer is used for burning the developed code on AVR STUDIO in to the microcontroller Chip. Here in our application we are using AVR microcontroller which is Flash Programmable IC.
