What is alcohol detecting system?
 a kind of system which can detect the
alcohol concentration in the cars to
prevent the behavior of drunk driving .

What we choose this project?
 These years, the cases of traffic accident caused by drunk driving have
increased rapidly.
 More and more people have realized that the drunk driving does great
harm to public security. It’s time to develop a kind of system which can
stop the drunk driving effectively.
 we try to develop this system which is available on every car.

FUTURE PLAN
advantages
Less cost for every driver to put it in your
car
Sensor is sensitive to detect alcohol
after drink two hours or more
Connect to the Android phone or iphone,
which could easily see diagram on the
screen
What we used in this system
MQ-3
ARDUINO MEGA
BLUETOOTH MODULE
MSP-430

What we have done before midterm and after midterm
The third step
The second step
The first step
1.Choose topic
1.Test arduino mega
and alcohol sensor
2.Find proper device
and material
2. Test different level
of alcohol
3.Set structure of our
system
3. Bluetooth
connection
4.Research on
alcohol level on after
drunk(20min)
4. Android
programming
1. Connect all the
devices
2. Package the all
parts
3. Set the diagram
on the ardroid
phone
4. Find one
mechanic device
that can connect
to the car

Problems

The sensor is so
sensitive so we have
to set all other
conditions at the
same and it’s a little
hard to calculate the
alcohol
concentration
Using the amarino
solves the problem
of programming of
phone, but it still
has some software
problems
Put the device to the
car, which connects
to the car ignition
Blood／breath alcohol concentration（BAC）
Blood／breath alcohol concentration(BAC) is the amount of
alcohol in the bloodstram or on one’s breath.
BAC is expressed as the weight of ethanol, measured in grams,
in 100 milliters of blood, or 210 liters of breath. BAC can be
measured by breath, blood, or urine tests.
Alcohol may affect Alcohol driving skills at BACs of 0.05
We could use the BAC calculate to do so
There’re some factor may affect the BAC, such as weight, age,
how fast you drink and so on.
Price in total
future
We cannot find other ways out to “persuade” driver to test
their breath every time whenever they want to use.
If they drunk, they may prefer to ignore the stuff even if they use it before.
Compulsory is only way for the system.
The system will connect to the ignition device, which means
the breath is the second key for your journey.
In addition, there’s an option that we try to put the system
on the key of your car because refitting the car is a tough
work for everyone to do.
