What you probably want is a PIR sensor (Passive InfraRed) like those used in motion sensitive porch light fixtures. Here's one example: http://www.sparkfun.com/products/8630
Note that they detect low-freq IR (around 10nm) which is what mammal bodies radiate, and they need a differential signal from motion so if you stand still (or wear a heavy parka) they may not fire.
