Warnings and instructions
• EasySense must be used only with Philips Xitanium
SR LED driver.
• The sensor is powered by a SR driver with a FELV
voltage 16-22V and should have at least basic
insulation.
• Do not apply mains power directly to the sensor.
• Do not cover the sensor during operation or mount
the sensor recessed.
• External infrared light source in the space might
have influence on occupancy detection.
• Incorrect location of sensor (e.g., outside the view
angle of the occupancy sensor) will result in
occupancy detection not functioning correctly.
• When recalibration is needed for adapting to
environment changes, make sure the SR driver is
power cycled. See System startup behaviors/Auto
calibration section for details.
• Faulty settings of the sensor might result in
undefined startup behavior; make sure field task
level is set higher than the background light level.
• Make sure the sensor, especially the occupancy
detection lens, is protected from damage during
shipment and handling.
• The application area of EasySense is designed for
a typical indoor environment (open/ private offices,
conference rooms, classrooms, corridors, etc.) in
normally heated and ventilated areas. EasySense
has no protection against aggressive chemicals or
water.

Introduction of EasySense
The Philips EasySense luminaire-mount sensor is the
ideal solution for per-luminaire, stand-alone control
of new light luminaires. It combines occupancy
sensing, daylight harvesting and field task tuning in
a single, compact package for easy OEM luminaire
assembly. EasySense operates with the established
Philips Xitanium SR LED driver standard to make a
simple two-wire connection between sensor and
driver, thus eliminating the need for multiple
components and auxiliary devices. The result is a
cost-effective and easy-to-design-in solution,
ideal for energy-savings. While the sensor pre-set
parameters are appropriate for most applications, an
intuitive app makes configuration during installation
fast and easy, if required.

EasySense overview
EasySense contains multiple functions in one
housing and uses two wires to connect with an SR
driver. (See wiring diagram in the Mechanical
design-in section.) Functions include:
• NFC antenna • Occupancy sensor (PIR)
• Light sensor
• Infrared receiver
• LED indicator
The application area of EasySense is designed for a
typical indoor environment (open/private offices,
conference rooms, classrooms, corridors, etc.) in
normally heated and ventilated areas. EasySense has
no protection against aggressive chemicals or water.
The sensor is normally mounted to a luminaire and is
optimized for a sensor mounting height of 2.5 m to 3 m.
NFC antenna
The EasySense sensor can be configured through
NFC (near field communication) using a smart phone
with the EasySense app. NFC is the set of protocols
that enables electronic devices to establish radio
communication with each other by touching the
devices together or bringing them into proximity to a
distance of typically 1 cm or less. Parameters for
lighting controls can all be configured. (More details
are available in the Lighting control section.)
Motion detector
The occupancy sensor is a PIR (Passive Infrared)
sensor that detects movement with an X-Y cross-
area under an angle of X = 72° and Y = 86°.
Two types of movements are defined in NEMA WD7
as follows:
• Major movement: movement of a person walking
into or through an area.
• Minor movement: movement of a person sitting at
an office desk reaching for a telephone, turning
the pages in a book, opening a file folder, picking
up a coffee cup, etc.
When installed in a typical office ceiling at H, the
sensor is sensitive to minor movements within X1 by
Y1 area. It will respond to minor movements down to
a few centimeters at the task area of a desk and is
sensitive to major movements within a range of X2
by Y2. The maximum recommended height to place
the sensor in the ceiling is 3 m to assure movement
coverage and detection. The PIR sensor reacts on
movement by means of a temperature difference,
such as the human body temperature versus its
surrounding temperature. A car that just starts its
engine is not seen by the PIR nor does the PIR see
people sitting within the car or a forklift truck.
Therefore, it is recommended not to use EasySense
in outdoor, parking or industrial applications.
Please refer to the EasySense datasheet for coverage
area details.

Sensor view shield
The sensor comes with an occupancy view shield
that can be used to block the movement detection
by the sensor in a certain area. The shield comes
inverted. (See Figure 2.) This view shield can be
pulled out, flipped and inserted back in the sensor
and then rotated so the correct area is shielded off
from the detection area. If such shield is not needed
in the application, it can be easily pulled out from
the sensor or left inverted.
Light sensor
The light sensor is a photo diode that reads average
light level captured under an angle of approximately
40°. The intensity of the illuminance depends on the
amount of artificial and/or natural light supplied in the
office, as well as how this light is reflected toward the
ceiling/sensor. The EasySense converts the illumi-
nance signal into ON/OFF or dimming commands to
the Xitanium SR driver in order to maintain a constant
light level on the desk. The sensor should be installed
with a minimum distance of 0.6 m to the window to
avoid the sensor looking outside. When the sensor is
mounted too close to the window it will look partly
outside. Sun reflection from cars or snow can reflect
directly into the sensor.
The sensor will then measure such high illumination
levels that it will drive the artificial light to its minimal
level or even switch off the artificial lights. The
optimum distance [Y] from the window to EasySense
can be obtained from Figure 4. This graph shows the
relation between the distance from the window to
the sensor [Y] and the height [H] of the sensor
(H, height of the sensor measured from ceiling to
bottom of window sill).
LED indicator
The product contains an LED indicator. The LED
indicator by default is enabled, and it can be disab-
led through the app. The behavior of the LED is as
listed below.
Yellow LED on: = vacancy & sensor is functional.
Red LED on: = motion is detected and hold time is
not expired yet.
IR receiver
The infrared receiver serves as a communication
portal for the commissioning tools for future version
of the sensor. Also, an RF transceiver is built in, in
compliance with RTTE and EMC regulation, and will
be enabled for future version of the sensor.

System startup behavior
and auto-calibration
System startup behavior
When the sensor is powered (mains of driver is
switched on or a momentary power dip is detected
by the sensor), the sensor performs an auto-
calibration routine.
Auto-calibration routine
Below describes the calibration routine.
• Light is switched on at maximum light level set by
max of AOC (adjustable output current).
• Light dims down to minimum dimming level.
• Sensor stores the value detected by the light
sensor.
• Light dims up to maximum light level which is set by
the field task level.
• Sensor stores the value detected by the light
sensor.
• A calculation is executed, and calibration set point
will be determined.
• Light dims down to the task level that meets the set
point.
Warning:
Make sure no objects are blocking the sensor’s
view and no surface reflectance changes occur
in the sensor’s view during auto calibration.

Lighting control
Fade to switch-on time is the time (T1 to T2) from
the point at which occupancy is detected until the
lights dim up to the max light output. This timer is set
to 0.7 sec and is not configurable.
Hold time is the time (T3 to T4) from the point
at which the last movement has been detected
(e.g., occupant left the room) until grace time starts.
This timer is set to 15 minutes by default and can be
configured from to 1 – 120 minutes.
Grace fading time is the time from T4 to T5 during
which the lights are being dimmed down from the
current light level to the background level. By default,
grace fading time is 10 sec and can be configured to
0 – 25 seconds.
Prolong time is the time from T5 to T6 at which the
background level is maintained at a fixed level.
Default prolong time is 15 minutes and can be
configured from 0 – infinity.
Fade to switch-off time is the time (T6 to T7) for
the lights to fade from background level to off after
prolong time is expired. This timer is set to 0.7 sec
and is not configurable.
Field task level is used to configure the required light
level on the task plane, which is also the maximum
light level of the luminaire. It can be configured
through the app. (See Task tuning.)
Switch-on level is a predefined output level that will
be activated when occupancy is detected. The
switch-on level is not configurable and is set to
100%, or the field task level if set lower than 100%.
Background level is a light level lower than 100%,
used to save energy when space is not occupied.
Terminology used in this chapter
All parameters are stored in the sensor,
and most of the parameters can be configured
through NFC.

Lighting control overview
EasySense controls the light output based on the
occupancy, daylight regulation and field task level.
When both occupancy- and daylight-based lighting
control are enabled, the light level is determined by
the lowest light level of the following:
• Occupancy-based set point (either the switch-on
level, background level or off)
• Daylight regulation set point (The daylight
regulation set point is the amount of light needed
on top of the available daylight.)
• Field task level
In case occupancy-based lighting control is disabled,
the occupancy-based set point is not used for
determination of the light level. In case daylight-
based lighting control is disabled, the daylight
regulation set point is not used for determination of
the light level. When both occupancy-based light
control and daylight-based light control are
disabled, the light output will continuously be on
field task level.
