THE SPARK

Majority of road accidents occur when the driver

is blinded by the light f rom an opposing vehicle

An aut omatic lighting control system could go a 

long way in providing the solution

FEATURES

An Aut omobile with built in luminous control

mechanisms.

Utilizes multiple sensors t o gauge parameters.

Multi-situation sensitive contraption utilizing PIC

16F877A

FORERUNNERSy AUTRONIC EYE : The f irst aut omatic headlight 

dimmery G UIDEMATIC  : It had a more compact dasht op 

housing and a swit ch that allowed drivers t o adjust 

the system's sensitivity threshold.

WHERE THEY FALTER

y

Do not have a compact location for the system.

y Non-responsive when driver approaches a vehicle

f rom behind.

DESCRIPTION

y The phot odetect or detects the presence of  opposing

vehicles by sensing the light emitted

y The ultrasonic sensor detects the ultrasound ref lected

f rom vehicles in same track .

y The pressure sensors determine the mass inside the

vehicle.

Continuesy The speedometer gauges the speed of the vehicle.

y The PIC16f 877A microcontroller compares these

values with suit able ref erence values.

y Subsequent adjust ments are made t o the position of  

the headlight using the mot or and the intensity usingthe relay.

HURDLES� Familiarization with PIC

� Inst ant aneous A-D Conversion.

� Non-availability of  a suit able pressure sensor.

� Interfacing of ultra sound sensor with PIC.

y Lack  of information regarding the head light 

focusing mot or used in Maruthi car.

TROUBLE SHOOTINGy The ref erence values for A-D conversion was

satisfact orily obt ained

y Phot o detect or section was adopted for co-

directional traff ic as well due t o the non-

availability of  suit able ultra sonic sensor

yMass dependent beam adjust ment was successf ully

tested primary level.

STATUSFinalized components based on compatibility and

availability.

Found out the ref erence value for comparison for the

phot o transist or.

Practical compatibility of  phot o transist or was testedin road.

Program was written for PIC using Mik ro C

CONTINUEDy The phot otransist or section for beam cont ol was

successf ully implemented breadboard level

y The beam adjust ment  corresponding t o vehicle

occupancy was successf ully implemented

breadboard wise

y The PCB design and layout was done based on

ORCAD
