Objective of the Project

To built an intelligent vehicle with safety measures, to Prevent Accidents of vehicles.

Features in the Project

Accident Indication

Suppose if any accident is detected, it can be indicated to  a nearest hospital. This is implemented using an Infrared sensor. The vehicle consist of a IR Transmitter and the IR Receiver is placed in two different zones.  When the vehicle comes into contact with the IR receiver, that will be indicated to the system and the zone information is passed to the remote place.  This is shown by glowing different LEDs for different zones.

Alcohol Sensing

An alcohol sensor is included in the vehicle for sensing whether the driver has consumed alcohol.  If consumed, then vehicle will be stopped automatically by controlling the motors.

Sleep Detection

Further more we can use an Eye blink Sensor, which can be fixed to the drivers, Head, to monitor whether the driver has slept, or about to sleep, so that we can alert the driver by vibrating the driver seat using DC Motors.


Power Supply:

Uses to generate DC +12V, +5V Power supply from the give 230V AC Supply

Eye Blink Sensor:

Used to convert the eye blink action into voltage pulses for every blink.

Signal Conditioning Circuits:

Used to convert the voltage pulses delivered from the eye blink sensor to ttl level signals which should be given to a micro controller for processing.

Alcohol Sensor:

Produces voltage ouput according the alcohol sensing level.

Motor Driver:

The signal output from the controller is not sufficient to drive a DC Motor. So a current amplification is necessary before giving to the motor. So the motor driver board is used

Motor Power Supply:

Used to generate the motor power supply of +12V DC from the 230V AC Supply.


Used to switch on/off the  power supply of the motor, as decided by the controller.

LED1 and LED2:

Used to indicate the status whether the vehicle has stopped due to  the Alcohol sensor, or the driver has slept by monitoring the Eye blink sensor.


Alarm is enabled whenever there is fault condition.
