hey there ppl!!

i m an electronics student and i have to come up (or rather follow) a design of some project for this year and i only have a vague idea about what i will do!!

i just know that energy reducing/saving projects will be highly appreciated, like for example a lighting system that switches on when a person enters the room and switches off when the person leaves, or projects along those lines!!

if any one can lead me to any good sites where i can find what i m looking for pls do so!!! thanks a lot btw!!

thanks again :D

dear,
you can search yahoo for sensors and specially photoelectric ones.like lifts if someone interuppts the passage of light the lift door stays open.and you need a proximity switch to see if someone is coming or leaving and a simple program
with best regards
