Overall, from the standpoint of detection performance, noise resistance,
causes of false detection and cost performance, the passive infrared type
is the most practical means of detecting the human body without contact.
All objects on the earth emit light in accor-
dance with their temperature and surface
characteristics. Naturally, light (infrared radia-
tion) is also emitted from our bodies. (This radi-
ation is emitted from the body surface, and is
centered around a wave-length of 10µm.)
When a person enters the detection area of
the sensor, the amount of infrared radiation
incident on the sensor varies by the
amount corresponding to the difference in
temperature between the body surface and
background.
That is, the sensor is actuated by the differ-
ence in temperature between human body
(which is a heat source) and floor, walls and
other objects forming the background.
These sensors detect the human
body by detecting the change in
incident infrared radiation.
