3.  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.

5.  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.

17. TRANSMITTER:
•Low Cost
• 1.5-12V operation
• Small size
• operates at 4.5 to 5.5 volts
RECEIVER:

19.  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.

20.  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
