Q
Why is a detection signal output even
though no object is in the detection area?
Detection error
1. Is there anything in front of the MA Motion Sensor with a
Just as light reflects in a mirror, the infrared light emitted by the sensor will
reflect off of an object with a reflective surface and return to the sensor.
If this occurs, change the angle of attachment of the sensor slightly (no
more than several degrees) as shown below.
2. Is the sensor detecting the surface on which it is
The sensor emits infrared light in the form of a spot beam that gradually
expands. The beam projector element is in the bottom part of the sensor,
and thus if the sensor is installed on a surface parallel to the beam (wall,
floor or ceiling), the beam may hit the surface and reflect back into the sen-
sor. We recommend that you raise the sensor slightly off of the installation
surface (approx. 50mm).
