The main goal of this paper is to get an instant notification if a user's breath contains an amount of alcohol that exceeds a certain limit. When a person is recognised as having a high amount of alcohol in their bloodstream, the system sends out a warning signal to their phone. Whenever the amount of alcohol in the blood comes within the detection range of a high alcohol level, the device generates an alert sound and flashes the LED. According to the manufacturer, this technology is only an upgrade to the existing alcohol detection systems that are now in use across the world. An alcohol-detecting sensor measures the quantity of alcohol in a person's breath and transmits the information to an Arduino, which subsequently controls the light and buzzer by sending commands to and from the sensor. This strategy provides low-cost development as well as attention to detail.
