We usually come
across drink and driving cases where drunk drivers crash their cars under the
influence of alcohol causing damage to property and life. So here we propose an
innovative system to eliminate such cases. Our proposed system would be
constantly monitoring the driver breath by placing it on the driver wheel or
somewhere the drivers breath can be constantly monitored by it. So if a driver
is drunk and tries to drive the system detects alcohol presence in his/her
breathe and locks the engine so that the vehicle fails to start.
In another case if the driver is not
drunk while he starts the vehicle and engine is started but he/she drinks while
driving the sensor still detects alcohol in his breath and stops the engine so
that the car would not accelerate any further and driver can steer it to
roadside. In this system we use an AVR family microcontroller interfaced with
an alcohol sensor along with an LCD screen and a dc motor to demonstrate the
concept. So here the alcohol sensor is used to monitor users breath and
constantly sends signals to the microcontroller.
The microcontroller on encountering high
alcohol signal from the alcohol sensor displays alcohol detection note on LCD
screen and also stops the dc motor to demonstrate as engine locking. The system
needs a push button to start the engine. If alcohol is detected at the time of
starting the engine the engine does not start at all. If alcohol is detected
after engine starting, the system locks the engine at that time.
