Accidents are increasing at a large pace, and various technologies are being introduced to reduce the accidents.

In this project we provide by means of accident prevention using eye blink where as the vehicle is stopped immediately and intimated wherever needed.

Vehicle accidents are most common if the driving is inadequate.

Driver drowsiness is recognized as an important factor in the vehicle accidents.

This project involves measure and controls the eye blink using IR sensor. The IR transmitter is used to transmit the infrared rays in our eye.

Functional description

Pin Diagram

Low power, high performance CMOS 8 bit microcontroller. 8K bytes of Flash, 256 bytes of RAM, 32 I/O lines two data pointers, three 16-bit timer/counters, a six-vector two-level interrupt architecture

VCC GND PORT 0 XTAL1 PORT 1 XTAL2 PORT 2 PORT3 RST ALE

TRANSMITTER:

•Low Cost• 1.5-12V operation• Small size

• operates at 4.5 to 5.5 volts

RECEIVER:

Keil compiler is the software used where the machine language code is written and compiled.

The machine source code is converted into hex code, this hex code is dumped into the microcontroller for further processing.

This is extended with alcoholic detection also.

If the person took alcohol who is driving then the vehicle will be stopped immediately by giving alarm
