Drunk driving is one of the major cause of road accidents especially in Nigeria where there is no controls or checks to the level of alcohol content of drivers. In this study, a vehicle alcohol and temperature monitoring system was simulated and constructed using an Arduino Uno microcontroller ATMega328. The circuit was simulated in Proteus8.1 design suit comprising an alcohol sensor, contactless temperature sensor, motor/relay driver, ignition, 16×2 liquid crystal display, and 5V DC power. The simulated circuit was constructed on a printed circuit board and tested for continuity and power ‘ON’. An evaluation performance test was also carried out using 40 volunteers that have consumed varying amounts of alcohol content ranging from two to fifteen standard drink and their blood alcohol content as well as body temperature were measured. The true positive, false positive, true negative and false negative were recorded. Results showed that the constructed device has sensitivity of 92% and specificity of 75% depicting that the system can correctly identify 92% presence of alcohol and 75% of alcohol absence with 90% accuracy. It however, failed to identify only 8% alcohol presence and 25% alcohol absence. The device if installed in a vehicle could be significantly useful in averting road accidents caused by drunk driving. Ensuring the public and commercial drivers have a clear understanding of the law and raising awareness of the impact drink drive has on road users is important to reducing its prevalence.
