A study on the Efficacy of Alcohol Detection in the prevention of Drunken Driving

Accidents on roads due to drunken driving have become increasingly common. We have developed a device which can prevent the accidents that occur due to drunken driving by stalling the vehicle. We are using the (MQ-3) sensor which can detect alcoholic content from the driver's breath. The Arduino NANO board is very flexible and can be programmed to the MQ-3 sensor's sensitivity requirements which in turn can actuate the relay to break the circuit which connects the starter motor and the battery, thereby stalling the vehicle. This circuit is quite compact and be integrated in all types of vehicles.
