occupancy sensors are de
signed to meet a wide range of
applications. Hubbell ceiling and wall
mounted sensors are available with the most
date sensing technologies on the market today. Hubbell offers passive infrared
and ultrasonic sensors as well as a multi
tech version. H

provide simple installation, easy setup, and reliable long
term motion detection.

settings to ensure that the sensor is providing maximum ROI and true maintenance
free "Install and Forget" operations.
Passive Infrared (PIR) sensors use a multi
gmented lens to divide the space in
zones. When a person enters the sensor's field of view, the Fresnel
™ lens focuses
the IR energy emitted by the human body onto a pyro
electric detector. When the IR
signature moves between zones, the sensor interprets this movement as occupancy
and turns on available lighting. PIR technology provides excellent long
Ultrasonic sensors utilize a volumetric sensing technology to monitor a specific area.
Transducers emit an inaudible wave pattern at a specific frequency filling the space
and bouncing off all surfaces in the coverage area. Ultrason
ic technology provides
superior minor motion detection.
technology sensors incorporate both PIR and ultrasonic technologies into one
compact device. By utilizing both technologies the sensors provide superior
occupancy detection in areas where a sing
le technology sensor would not.
