Integration of Advanced Vehicle Monitoring and Alcohol Sensing System for Modern Vehicles to Prevent Road Accident

Road Traffic accident has become a very common issue in Bangladesh. There are several reasons behind those accident. But the most common reasons are unfit vehicle and drunk driver. For that reason, we have developed this project which detects the drunk driver and checks the document like vehicle fitness certificate. We have developed this project based on microcontroller where the microcontroller gets the input from Alcohol and eyeblink sensor. Multiple sensors are installed on the steering wheel and adjacent to the driving seat which can detect the alcohol level from the breath of the driver and monitor the eyeblink. If the level of alcohol crosses a certain level and eyes remain closed for certain time the microcontroller will stop the engine ignition. A document checking algorithm is formulated in the microcontroller which checks the fitness validity of the vehicle. A GSM and a GPS module is also integrated with the system which shares the location of vehicle with related personnel and authority if any anomaly is found. Implementation of this idea in our country, certainly can reduce a large number of vehicle accident due to drunk driver and unfit vehicle and at the same time can increase government revenue.
