This document describes a project to prevent vehicle accidents by detecting a driver's eye blinks using an IR sensor. If the sensor detects no eye blinks for a set time, indicating potential drowsiness, it will send a signal via RF to receivers in the vehicle to stop the motor and alert emergency services. The system uses a microcontroller, eye blink sensor, RF transmitter and receiver, motor driver, and other components. It aims to reduce accidents caused by drowsy or intoxicated driving. Possible extensions include adding alcohol detection to also stop the vehicle if the driver is intoxicated.

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
