AIM:

The main objective of this project is to develop an embedded system which detects the alcohol.

(Automatic Engine Locking system for drunk driver )

 

IMPLEMENTATION:

This project is implemented 8051 development board interfaced with alcohol sensor, Buzzer.

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.

 

[sam id=”5″ codes=”true”]

 

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 8051 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

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 contries 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.

SOFTWARE:

Embedded ‘C’

Keil to write code

Flash magic to burn the chip

HARDWARE:

  1. Power Supply
  2. Alcohol sensor
  3. Buzzer
  4. MICROCONTROLLER 8051
  5. Driver circuit
  6. Engine/MOTORS
  7. LCD
  8. Lm324 op-amp

 

ADVANTAGES: Low cost, automated operation, Low Power consumption.
