INTRODUCTION
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.
WORKING
The eye-blink sensor illuminates the eye with infrared light, monitoring the changes in the reflected light
The sensor output is active high for Eye close and can be given directly to microcontroller for interfacing applications.
When this output remains high for a specific time period say10 sec , the driver is taken to be asleep.
Consequently a buzzer is activated in order to wake the driver.
The motor of the vehicle is slowed down through a relay switch so as to prevent impending accident.
BUZZER
A signaling device, usually electronic, typically used in automobiles, household appliances .
Usually illuminates a light on the appropriate button or control panel.
Sounds a warning in the form of a continuous or intermittent buzzing or beeping sound.
ADVANTAGES
The advantages are:
It can be used in wireless technology.
The eye blink module of this project can be separately used for RFID detection in global
industries.
It can be used in image processing application by camera module
CONCLUSION
A complete study on road safety is going to be the next boom in the automobile industry for it to flourish and survive as every human being wants to be safe with all the comforts at the same time
Reduce the number of accidents.
It is also used for security alerts where 24 hours surveillance is required
