● When measuring in narrow locations or inside holes, mount the prod-
uct so that optical path from the light emitting part to light-receiving
part is not interrupted.
● Mount the sensor to a wall as follows, so that the multiple light reflec-
tions on the wall do not reach the light-receiving part. When the reflec-
tion factor on the wall is high, it is effective to use a dull black color.
