Note:
R
Detection becomes difficult when
there is little difference between the
temperatures of objects and the
surrounding environment, such as
during summer. Conversely,
detection becomes easier when
there is a large difference between
the temperatures of objects and the
surrounding environment, such as
during winter or at night.
R
Detection does not occur when there
are obstacles in front of the infrared
sensor. Remove the obstacles or
change the installation location.
Direction of motion
It is easier to detect objects that move
sideways in front of the motion sensor,
and more difficult to detect objects that
move directly toward the front of the
motion sensor.
