4.3. Installation Consideration
Ӽ What do I need to consider before installing the PIR sensor?
It is recommended to install the sensor at a height between 1.8m and 2.4m in order
to get the best coverage of the area.
The PIR sensor coverage area is approximately conical in shape and is broken up
into zones by a Fresnel lense - see below for a view of coverage area. The target to be
detected must pass either into or out of one of these zones in order to be detected.
Small targets can sometimes move between these zones and not be detected because
they never pass into or out of a zone.

Please note also that you should not point the PIR towards an area with constantly
moving objects such as vehicles, small animals, hanging objects or trees that can
move in the wind.

Targets moving directly toward or away
from the sensor may sometimes escape
detection, as PIR sensors tend to be less
sensitive to this type of movement - this
