Alcohol Detection with Vehicle Warning

It takes being alive and healthy to tackle challenges for sustainable development. The source of drinking and driving has led to the loss of life and property. Control measures to ensure drivers are not under influence of alcohol while driving such as Blood Alcohol Content (BAC) check remains unrealizable due to used personnel, equipment, and maintenance cost involved. A less consuming effort has been proposed using MQ3 gas sensor mounted on the steering wheel, powered by the ignition of the vehicle to detect alcohol processed by Arduino Uno. In this project, an Arduino Uno compares the output with a set threshold for compliance. If the threshold is exceeded four modules are simultaneously triggered. Fuel supply control module is activated by a relay to cut-off engine and bring the vehicle to stationary position. The Liquid Crystal Display (LCD) module display is activated to show alcohol has been detected. The Global Positioning System (GPS) module is activated to detect exact location co-ordinates. The Global System for Mobile (GSM) module is activated to send notice on the LCD display and location co-ordinates to the subject’s next of keen for immediate attention
