The X-Eye Presence sensors provide the following functionalities:
1. Presence & Proximity detection - detects if a person or object is present and indicates the distance
This information is translated into an API message which has the following format:
When implementing distance zone triggers, consider the
following:
• When no person is in front of the sensor, the distance
zone will be 1.
• If the position of a person overlaps multiple distance
zones, only the number of the slot which is closest to
the sensor is given.
• The absolute physical distance ranges of the distance
zones can be customized. Please see section 5
"Settings", page 6.
The X-Eye Presence sensors utilizes Infrared proximity technology
to detected if a person or object is present. The working principle is
that an IR beam is transmitted, which is reected back by the nearest
person or object in front of the sensor. Based on the angle of the
reected IR beam, the distance of the person or object in front of the
sensor is calculated.
3.1 - Presence & Proximity detection
The X-Eye Presence sensor divides its detection range
into 10 distance zones. Each time a person or object in
front of the sensor move into a new distance zone, an API
command is triggered, indicating the current distance
zone. In the table below, the absolute distance ranges for
the default distance zones are provided:
The following section will cover this functionality in detail. Please note that for each API example in this document,
X-talk interface address 001 is used (X001). When the sensor is connected to another X-talk channel, replace the
"001" with the applicable X-talk address.
X= distance zone value between 1-10

The X-Eye Presence sensor can also indicate the distance as a raw decimal value
X= raw distance value value between 1-255
X001A[X]
X001S[4:1]
Per default, the detected distance is always indicated as
distance zones and not via raw decimal values. In order to
activate distance indication via raw decimal values, send
the following setting:
The raw decimal value is a unltered direct AD conversion
of the analog signal provided by the core IR measurement
component of the sensor and will uctuate highly We
therefore recommend to not use Raw Distance Value
mode for normal operation. Instead, the Raw Distance
Value mode is intended to be used a reference for when
wanting to create custom distance zone ranges.
Please see section 5 "Settings", page 6, for more
information on creating custom distance zone ranges

Raw distance value of detected distance is "7"
Raw distance value of detected distance is "51"
Raw distance value of detected distance is "178"

The X-Eye Presence sensor can be connected to any X-talk interface and is therefore compatible with all Xperience
controllers. Make sure the X-Eye Presence sensor is connected to the X-talk interface before powering the Xperience
controller. Otherwise, the X-Eye Presence sensor will not be recognized by the Xperience controller and no sensor output will
be provided.

The long-range X-Eye Presence sensor (XY-176) draws a peak current of 350mA. When connecting multiple XY-176 sensors
to a controller, please make sure that the total amount of required current is within the specication of the controller and its
power supply source. For example: when using a XN-185 controller connected to a 5V/2A USB power supply, the maximum
amount XY-176 Presence sensors which can be connected to the controller is 5. (2A / 0.35A = 5.7 ≈ 5 sensors)

Bright light sources aimed directly into the sensor or onto
the detection surface can cause inaccurate sensor output.
Make sure that the sensor is positioned in such a way that
it’s not directed towards any (strong) light source, such as
a halogen lamp or (compact) uorescent lamp.
In practice, this also means that the sensor is not
suitable for outdoor applications as the sun will cause
interference on sunny days.

Objects in front of the sensor interrupt the IR beam and
cause inaccurate sensor output. Make sure the sensor has
a clear view and is not obstructed by any objects within its
detection range.
Panel cut out
Both the transmitting and the receiving lens of the sensor need to have a clear view of the person standing in front of it. When
placing the sensor behind a front panel which does not have a transmittance in the IR spectrum (see previous section), a
cut out needs to be made. The recommended mechanical dimensions of the cut out are provided in the datasheets of the
X-Eye Presence sensor and are marked with magenta lines in the mechanical drawings.

In case the sensor needs to be placed behind a transparent
front panel such as glass or acrylic, make sure the material
has a high transmittance with an emitted spectrum
wavelength of 850nm (+/-70nm).
Please note that most commonly used types of glass
and acrylic do not have a transmittance in the IR
spectrum and can therefore not be placed in front of the
sensor. We recommend to use black "IR acrylic", typically
used for example in remote controls. Or alternatively, make
a cut out in the front panel (see next section).
The material in front of the sensor needs to be completely
smooth (e.g. no sand brushing or markings). The clearance
between the sensor and the front panel needs to be 1mm
or less.
<1mm

The ambient temperature has a minor inuence on the detection range and the distance zones mentioned on the previous
pages. The default distance zones are divided in such a way that the X-Eye Presence sensor works most accurately in the
temperature range between 16-26 degrees Celsius (61 to 79 Fahrenheit). When operation at colder or warmer temperatures
is expected, it is recommended to create custom distance slots. Please refer to the API document for instructions on how to
do so, or contact [e-mail] for help.

When using multiple X-Eye Presence sensors in one application, make sure that they do not point to the same location. This
can cause cross interference as the reecting beam of a sensor can reach the receiver of and adjacent sensor, resulting in
unstable behavior of the sensor. Therefore, when using multiple sensors facing in the same direction, it is recommended that:
>80cm
• the sensor are placed in vertical position. This reduces
the chance of cross interference due to the shape and
mechanical dimensions of the sensor's casing.
• the sensor are placed at an outwards directed angle, so
that the beams of the sensors diverge and are not parallel
to each other
• that each sensor is placed with a
minimum clearance of >80cm.
and/or
and/or
Narrow detection beam
All X-Eye Presence sensors have a narrow detection
beam angle of approximately 5.5 °. Please take this into
consideration when designing your setup and determining
the position of the sensor.

The XT-EF Series has multiple settings which determine the behaviour and output of the sensor. The settings can be adjusted
by sending X-talk setting commands via the API. After a power cycle, the settings always return to back to default.

Setting 10-29: Custom distance zone values
X is a value between 1-250 and it's default value is 10.
It indicates the interval in mS at which a sample is taken
from the distance measurement data. So the lower the
X value, the longer the time between two outputs and
vice versa. Please note that typically this setting does not
need to be adjusted.
For more info, please see section 3.1, page 2 and 3.
The total range of raw distance values is 1-255. The raw
distance value is a unltered direct AD conversion of
the analog signal provided by the core IR measurement
component of the sensor. This means that the raw
distance value has a direct correlation with the physical
distance measured. There are 10 distance zones available
in which the total range of raw distance values is allocated.
Per default, the distance zones are divided as indicated in
the tables below. Setting 10-29 can be used to overwrite
the default raw distance values for each distance zone,
facilitating custom distance zones.
Please note that typically it is not necessary to create
custom distance zones, as for most application the default
distance zones provide enough information to build the
desired application.

Step 1 - Setup
First, connect the X-Eye Presence sensor to an
Xperience controller. Secondly, power the Xperience
controller.
The green status LED of the X-Eye Presence sensor
should go on. The status LED of the controller will
start to blink and once power-up is completed will be
lit continuously
Step 2 - Test detection
Stand +/-30cm in front of the X-Eye Presence sensor.
Both the green status LED of the sensor and the status
LED of the controller should blink.
Move in perpendicular direction towards or away
from the sensor
Both the green status LED of the sensor and the status
LED of the controller should blink each time your enter
a new distance zone.
For a full test we recommend to connect the setup to
a mediaplayer or PC and test all API commands listed
in this document (see section 3, page 2-3). For more
information on how to setup a test for your controller,
please see the Quick Start Guide of the Xperience
controller you are using. These are available on
