Motion sensors are sensitive in the 8-12 micrometer range of infrared energy, which is the range that corresponds with the temperature of human skin, about 93 degrees Fahrenheit. Motion sensors detect changes in infrared energy, but only if the change is rapid. For example, if someone walks past a motion sensor it will pick up the change in energy and trigger the alarm. Heating and cooling your home won't trigger an alarm because the change in energy is too slow.
