Technology for Today’s Needs
Dual technology occupancy
sensors use both passive
infrared and ultrasonic
technologies for maximum
reliability. These sensors also
minimize the risk of false
triggering (lights coming on
when the space is unoccupied).
Both ultrasonic (US) and passive
infrared (PIR) technologies must
detect occupancy to turn lighting
on, while continued detection by
only one technology will keep
lighting on. The dual technology
sensors are the best performing
sensor for most applications.
Dual Technology
Ultrasonic technology senses
occupancy by bouncing ultrasonic
sound waves (32kHz - 45kHz) off
objects in a space and detecting
a frequency shift between the
emitted and reflected sound waves.
Movement by a person or object
within the space causes a shift in
frequency, which is interpreted as
occupancy. Ultrasonic occupancy
sensors are good at detecting
minor motion (e.g. typing, reading)
and do not require an unobstructed
line-of-sight, thus making them
suitable for applications such as an
office with cubicles or a restroom
with stalls.
Ultrasonic (US)
H-MOSS
feature the latest in
technological advances.
Adaptive Technology
Adaptive Technology is a Hubbell breakthrough that delivers benefits
to the building owner and occupants. The building owner gets
reduced energy costs, fewer adjustments and less maintenance. The
building occupant experiences fewer false-offs, disturbances and
lower energy costs.
Adaptive technology sensors use microprocessor-based technology
which makes all the decisions for setting adjustments. Internal
software constantly monitors the controlled area and automatically
adjusts the sensitivity and timer based on environmental history. This
means that instead of manually adjusting the sensor for seasonal
changes, modified airflow, and furniture layout or occupancy pattern
changes, the sensor will automatically adjust itself. These automatic
adjustments will eliminate the need for multiple adjustments by
maintenance, personnel or outside contractors.
Hubbell offers adaptive technology throughout its product offering
(wall switches, ceiling and wall mount sensors) in conjunction with
dual technology (ultrasonic and passive infrared), ultrasonic, and
passive infrared products.

Occupancy Sensors
Passive Infrared (PIR)
Passive Infrared (PIR) technology
senses occupancy by detecting
the difference between heat
emitted from the human
body and the background
space. PIR sensors require an
unobstructed line-of-sight for
detection. These sensors utilize
a segmented lens, which divides
the coverage area into zones.
Movement between these zones
is interpreted as occupancy. PIR
sensors are good at detecting
major motion (e.g. walking) and
work best in small, enclosed
spaces with high levels of
occupant movement.
