Stands for Passive Infrared. This technology is used in motion sensors to detect movement. The devices are passive because, unlike a TV remote, they do not generate any infrared light - they only detect it. Infrared light can be generated by heat, so motion sensors with PIR can detect the heat produced by people and warm-blooded animals.
