PRODUCT MANUAL | XT-EF SERIES AIR GESTURE SENSOR
3. Functionalities and API commands
The XT-EF Series sensors provide the following functionalities:
1. AirButton
- detects when a hand enters or leaves the sensor's detection field
2. AirSwipe
- detects swipes to the left, right, up and down
3. AirWheel
- detects circular movements clockwise and anti-clockwise
The following sections will cover each of these functionalities 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.
channel.

hand left detection field
When implementing AirButton triggers, consider the
following:
• The sensitivity/range of the FAR and NEAR detection
level can be adjusted. Please see section 3.4
"Settings", page 9.
• The maximum range for AirButton detection is
different for each XT-EF sensor model. Please see the
overview on page 1 for more info.
• AirButton detection can be disabled. Please see
section 3.4 "Settings", page 9.
• When an AirButton (far or near) is detected, the sensor
checks for a short period of time if an AirGesture is
detected as well. This avoids that both an AirButton
and AirGesture API-command is send during an
AirGesture event. The duration for which the system
checks for AirGestures - and the AirButton trigger
is delayed - is adjustable. Please see section 3.4
"Settings", page 9.

The XT-EF Series sensors consist out of 2 main parts: the AirGesture
Driver and the Electrode. The sensor's electrode creates an electrical
field which defines the detection area of the sensor. The driver
analyses the signals coming from the electrode and connects to
the Xperience controller via X-talk. The XT-EF6xx sensors all have a
separate driver. The EF30 sensor has an integrated on-board driver.

The XT-EF Series sensors can detect when a hand is placed above the sensor (both far and near) as well as when it leaves
the detection field. The API output for these triggers is as follows:
