what sensor shall i use to track human movement in a room???

I'm working on a LED lighting project for home usage. It's still in design stage now. I have the concept but find it difficult to make a feasible prototype plan. I know little about arduino now. But the deadline is close TOT.

the thing is, I need to track human movement in a room. I need real-time data so the lighting system can provide light accordingly. Camera can't help since it's dark.

Can anyone help me on this???

You'll need some sort of Passive IR sensors (Passive infrared sensor - Wikipedia) to do this.

Also, are we talking about one person tracking, or multiple people tracking? Are you with where they have been, or with where they are going? Or is it that you just want light where someone is?

I think that SparkFun has some of those PIR sensors.

A camera could, with some IR illumination.

However, if you're that close to your deadline, an Arduino is not the best choice.

My usual comment is, if you have to ask the question, you're probably not the person to do it.
