Detection Area
Detection Area:
The PIR sensor has a range of approximately 110 degrees horizontally, and
approximately 70 degrees vertically (see diagram).
You can test the functionality of the motion sensor as well as the detection area by
setting up the sensor, setting it to
chime mode
and then moving about in the area
you want to protect. It will chime each time it detects movement, allowing you to
obtain a very accurate impression of the field of view.
Important:
Any obstructions in the environment will reduce the sensors effectiveness. It
•
can’t see through walls! Even a thin sheet of glass will significantly impair the
range of the sensor, as glass blocks more infrared radiation than visible light.
Small animals (such as a cat or similar) can, under some circumstances, trigger
•
the PIR sensors. Therefore, we suggest that the PIR sensors are not suited to
areas where pets are routinely kept.
