passersby detector SOS
January 3, 2012
hi everyone! i am a vocational student living here in Philippines. Now i have a project in Robotics and Artificial Intelligence class.. at first i proposed a light follower/obstacle avoider/line follower robot. Unfortunately, it was rejected by my prof because it doesn't answers any problem and it was so easy. then, i came out with a concept about "passersby detector."
What i want in my project is that when someone enters the room in "entrance door", then the lights and fan will turn on, lights and fan will only turns off when that person will go out passing in "exit door" ...
can anyone here help me in what technology can be easily implemented (something that i can attach near the door like laser, motion detector, etc), I BADLY NEED SOME IDEAS, DESIGNS, LOGICS or anything that can help me... please guys...and something that I can be finish in one weeks... T-T
COMMENTS, SUGESTIONS AND ANY FORM OF HELP ARE MUCH APPRECIATED... (> T-T )>
