What tasks do sensors fulfl?
Mounting heights, room sizes, detection geometry and indoor climate
conditions – individual building needs are frequently complex. The right
solution can quickly be found though with a modular sensor kit
consisting of diverse, variably settable sensors. Several questions must
however initially be answered to enable correct selection.

Which technology is
most suitable?
Two sensor technologies are suffcient to fulfl all standard demands for
motion and presence detection, and one technology is not better than
the other. Intelligent use depends on the specifc requirements, and a
fundamental differentiation is made between the basic sensor types of
passive infrared or high frequency sensors.

Tip: determining the right mounting
location for PIR and HF sensors
Selecting the right installation location for a sensor
prevents erroneous switching, triggered for example
by temperature fuctuations, strong draughts or
vibrations. Sensors must be mounted so that their
detection ranges are not impaired by machines,
cranes, vehicles or doors.

Motion sensors for small to
large spaces and car parks
Rooms and halls for packing, assembly and logistics work
are typical applications for motion sensors with square
geometry. The precise determination of detection ranges
provides major savings potential, especially in large halls, as
these can be divided into precise segments during the
planning process. In this way only the specifcally required
area is illuminated but not the complete hall.
High quality and strong-range sensors with circular
detection are especially suitable for car parks and under-
ground garages, facilitating standard-compliant and energy-
effcient lighting. Another important factor is that parking
areas completely covered by sensors signifcantly increase
the subjective feeling of safety.
