ABSTRACT :

Freak accidents are commonly hitting the headlinesnowadays due to factors like carelessness, drowsiness ofthe driver etc.

System designed to detect the drivers consciousness

every moment and guide him/her throughout thejourney .

Controls the speed of the vehicle based on thedrivers consciousness.

This system prevents the road accidents and alarmsthe driver.

OBJECTIVE:

To design a system which controls the speed of thevehicle depending on the drivers consciousness.

To design a system used GSM technology to informthe accident identification and alert the owner usingSMS.

FLUX SENSOR

Photo of thesensor

Theory

By varying the position of flux

sensor wire the output will change.

It works on the principle of forcesensor.

4K Bytes of In-System Reprogrammable Flash

Memory.

1,000 Write/Erase Cycles.

Fully Static Operation: 0 Hz to 24 MHz 128 x 8-bit Internal RAM.

32 Programmable I/O Lines.

2 -16 Bit timers s used.

Six Interrupts are present. Programmable Serial Channel.

Low-power Idle and Power-down Modes.

Parallel Ports4.

FEATURES OF MICROCONTROLLER(AT89C51):


12/25

INTERFACING DC MOTOR WITH C :


13/25

DC MOTOR :

It can be used to interface with the Microcontroller.

By interfacing this motor we can control the speed of the motor,direction ofrotation.

It can also be used for encoding of the rotation made by dc motor .

Usually H-bridge is preferred way of interfacing a dc motor.

The H-bridge has four switching elements ,they are
