●
Human activity sensor detects the gap between the room temperature
and human body temperature. The available ranges may be different
depending on the surrounding temperature, clothes, etc. Human
activity sensor may mistakenly detect the heat source such as direct
sunlight, animals (dog, cat, etc.), warm air from air conditioner, heater,
electric pot, etc.
●
Sideways or lengthways movement can be detected easily, but back
and forth movement or a slight movement may not be detected strictly.
●
Human activity sensor may not work properly when there is a reflecting
object (mirror, etc.) in the available ranges or any objects between the
human activity sensor and person.
