 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.

Microcontroller PIC Buzzer DC Motor Eye blink sensor Comparator

 The eye-blink sensor illuminats the eye with infrared light, monitoring the changes in the reflected light  The output is active high for Eye close and can be given directly to microcontroller for interfacing applications.  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

L293D Pin description LOGIC CIRCUIT Functional description

 L293D is a dual motor driver integrated circuit (IC).  act as current amplifiers. This higher current signal is used to drive the motors.  L293D contains two inbuilt driver circuits.  In common mode of operation, two DC motors can be driven simultaneously, both in forward and reverse direction.  Enable pins 1 and 9 (corresponding to the two motors) must be high for motors to start operating.

 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.

 consists of two lines, 20 characters per line.  3 control lines and 8 I/O lines. - 8 data pins D7:D0 - RS: Register Select - R/W: Read or Write - E: Enable (Latch data)

 MikroC is a powerful, feature rich development tool for PIC microcontrollers.  ProvideS the programmer with easiest possible solution for developing applications for embedded systems, without compromising performance or control.

The prime purpose is to provide safety measures.  It is used for Automatic parking.  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 mera module

 Development of this kind of model reduces the risk of road accidents  After complete research and development of this project, it can be implemented on every vehicle in the industry thus increasing safety on roads.  Drivers who have been driving for long hours wouldn’t have to worry even if they fall asleep suddenly and therefore passengers are also safe.

 Development of a hybrid microcontroller for a vehicle which also consists of an alcohol detector which will sense if the driver is drunk and would not start the vehicle.  If the person who is driving takes alcohol then the vehicle will be stopped immediately by giving alarms.

 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.
