The main aim of this project is to design a system that can identify whether the person, driving the vehicle, is in complete conscious state or not. The designed and developed system is installed in the module confining microcontroller, alcohol sensor and Bluetooth module.

Block Diagram:

Working Principle:

From the above block diagram,

If the driver is drunk, the alcohol sensor fixed to the microcontroller will identify the alcohol content and its output will be triggered. This output of the sensor will be sent as an input to the microcontroller. Thus, the microcontroller continuously sends real time sensed alcohol detected values to the Bluetooth application where police is using at the scene, now android application analyses the streaming sensor values and display the level of alcohol detected.

If the alcohol level is above the normal range then it displays the detected level along with corresponding violated due amount and also sends those information to the police data base and in turn violation due amount will be placed via SMS to the driver.
