Prevention from Road Accidents due to Drunk Driver using IOT

Drinking alcohol is common in social gatherings and parties in some societies. Driving vehicles after drinking may cause road accidents. This paper aims to detect alcoholic drivers and stop them from driving using an IoT system. It is implemented using the Arduino micro-controller. The driver’s alcohol level is measured using an alcohol detector connected to a micro-controller in real-time. When the level of alcohol crosses a permissible limit, the vehicle ignition system will be turned off and the GPS module will capture the present location of the vehicle. Also, the GSM module will automatically send distress messages to police or family members.
