DESCRIPTION:
Most of these days, we hear lot of accidents due to drunken driving. Drunken
drivers will not be in stable condition and so the rash driving is the inconvenience for
other road users and also question of life and death for the drunken driver and for others.
The main purpose behind this project is “Drunk driving detection”. Now a days, many
accidents are happening because of the alcohol consumption of the driver or the person
who is driving the vehicle. Thus Drunk driving is a major reason of accidents in almost
all countries all over the world. Alcohol Detector in Car project is designed for the safety
of the people seating inside the car. This project should be fitted / installed inside the
vehicle.In this project, we are developing an Auto Lock System. Alcohol sensor will be
attached with our microcontroller. While alcohol wafers smelled by the sensor. Sensor
sends the input voltage to microcontroller. If there are any traces of Alcohol above the set
limit, then the system will lock the Engine at the same time will automatically gives a
buzzer We can avoid accidents by checking the driving people on the roads. So that we
can avoid accidents.The system uses a compact circuitry built around Flash version of
AT89S52 microcontroller with a non-volatile memory capable of retaining the password
data for over ten years. Programs are developed in embedded C. ISP is used to dump the
code into the microcontroller
SOFTWARE:
1. Embedded C programming.
2. Keil software
3. Express SCH for Circuit design.
4. Proteus for hardware simulation.
5. ISP to burn the chip
HARDWARE:
1. Power Supply
2. Alcohol sensor
3. Buzzer
4. AT89S52

So that we can avoid accidents.The system uses a compact circuitry built around Flash version of AT89S52 microcontroller with a non-volatile memory capable of retaining the password data for over ten years. Programs are developed in embedded C. ISP is used to dump the code into the microcontroller SOFTWARE: 1. Embedded C programming. 2. Keil software 3. Express SCH for Circuit design. 4. Proteus for hardware simulation. 5. ISP to burn the chip HARDWARE: 1. Power Supply 2. Alcohol sensor 3. Buzzer 4. AT89S52 www.svskits.in SVSKITS svskits@gmail.com, CONTACT: 9491535690, 7842358459
