Q
When you say "a temperature difference
between the object and the background of 4°C
or higher", what does "background" mean?
The background is the temperature of the environment surrounding (but not
including) the object to be detected, such as the ground, walls, and ceiling.
When a person enters the sensor's detection area, the quantity of infrared
radiation incident on the sensor changes by an amount equivalent to the
temperature difference between the person and the background. The MP
motion sensor ‘NaPiOn’ detects a person by detecting this change in inci-
dent infrared radiation. In other words, the sensor operates in response to
the difference in temperature between the human body, a source of heat,
and the background such as the floor and walls.
