Non-Invasive Alcohol Detection for Drunk Driving Prevention

This prototype aims to prevent the drivers who are not in the condition to drive and prevent them from any mishaps. This research proposes the development of a portable prototype which can be installed in a vehicle that can perform a quick check on driver's intoxication before starting the engine. In this prototype, a two-step mechanism ensures that the driver is not under alcohol influence and will be able to drive without any difficulty. Firstly, the driver has to place his/her finger on the Heart Rate sensor, if the heart rate is below the threshold value then the engine will ignite right away. However, if the heart rate exceeds above a certain threshold, the alcohol sensor will check the driver's Blood Alcohol Concentration (BAC). If the sensor detects alcohol it will prevent the vehicle from starting and send alerts to the emergency contacts of the driver.
