Q
Q
Should I assume that detection is not pos-
sible in direct light?
Is there an easy way to verify sensor
operation?
The maximum ambient operating illumination of the sensor is 30,000 Lx.
Even in bright sunlight, and even if light shines directly on the sensor or on
the object of detection, the sensor will operate correctly as long as the illu-
mination does not exceed 30,000 Lx.
However, if an inverter light is directly within the detection area of the sen-
sor (plus or minus several degrees), the sensor will not operate correctly.
This is because the sensor cannot distinguish between light emitted from
the sensor and light from the inverter light.
The sensor will operate correctly in the direction of
the sun as long as its optical axis does not point
directly toward the sun. The field of detection of the
sensor is plus or minus several degrees, so there
will be no problem if the sensor’s optical axis is
shifted 15° away from the sun.
Connect the sensor
as shown at right to
have an LED illumi-
nate when the sen-
sor detects a person
or object.
* Use a resistor value appropriate
for the current that is to flow
through the LED.
