Infrared presence detectors sense any moving object which can’t be detected by the human eye. Since the primary source of infrared radiation is heat or thermal radiation, any object which has a temperature radiates in the infrared. Even objects that we think of as being very cold, such as an ice cube, emit infrared. The warmer the object, the more infrared radiation it emits.
