1. Introduction
1.1. About the TeraRanger Evo Swipe
The TeraRanger Evo Swipe offers gesture recognition of close-range left to right and
right to left movements. It offers detection capabilities from just 10 cm up to 50 cm
using two pixels in order to detect the sense of movement.

The TeraRanger Evo Swipe has zero open electronics and provides an ABS protected
enclosure, resulting in a dust-proof and robust operation.

2. Mechanical integration
2.1. Modular design (clip-on, clip-off)
The mechanical design of the main sensor module (black) allows easy assembly to its
backboard (yellow) using a simple ‘clip-on’ technique. When clipping the two together,
please ensure there is no visible gap between the black and yellow parts.
Figure 2 -Modular design of the TeraRanger Evo Swipe sensor
2.2. Mechanical design and mounting
The TeraRanger Evo Swipe sensor offers an ABS housing (both: sensor and backboard)
with an option to mount the sensor using 2 holes compatible with M2 screws.
Figure 3 illustrates the external dimensions of the TeraRanger Evo Swipe sensor.

Figure 3 - TeraRanger Evo Swipe external dimensions, USB backboard
The USB Backboard includes two slots for mounting the sensor using standard M2
screws. The following methods can be used to mount the TeraRanger Evo Swipe sensor:
1. Front-panel mount using the M2 screws
2. Back-panel mount using the 2mm ledge on the front side of the sensor
Figure 4 illustrates the two different mount methods. The prior solution allows for easy
surface attachment and rapid evaluation of the sensor. The latter provides a more
discreet installation and supports design-in projects by installing the sensor behind a
surface (e.g panel), ideally with 2mm thickness.

2.3. Mounting solutions
When choosing a place for mounting the TeraRanger Evo Swipe, please consider the
following recommendations:
●Mounting close to sources of heat or strong electromagnetic fields can decrease
the sensing performance
●Do not mount anything directly in front of the sensor or in a cone of
approximately +/-35° around the central optical axis of the sensor
●It is advisable to avoid having other sources of Continuous Wave or modulated
Infrared light sources near the sensor
●Please consider that dust, dirt and condensation can affect the sensor
performance
●It is not advised to add an additional cover in front of the sensor
During assembly and integration, please observe all common ESD precautions. All
optical surfaces (sensor front) should be kept clean and free from contact with
chemicals.

3.2. Connecting the TeraRanger Evo to a Host Computer
3.2.1. Windows OS
In Windows it is also possible to use any terminal emulation software for data display.
Terabee often works with and suggests using HTerm software. Please follow the
provided link to download the software file (http://www.der-hammer.info/terminal/),
and select the file appropriate for your platform.
Tested with version 0.8.4 on Linux x64 and Windows 10 x64 platforms.
When using Windows, extract the downloaded zip file to the selected folder,
openitanddouble click on the “HTerm.exe” file.
When using Linux, extract the downloaded tgz file to the selected folder, make sure that
you have execution permission for the file “hterm” (command: chmod u+x hterm),
double click on the “hterm” file or run it from terminal while in its directory: ./hterm.
On Linux, consider removing the modemmanager package if you are sure that
it is not required by your system setup. This will shorten the initialization time
of serial devices in the Linux system:
sudo apt purge modemmanager
Connect the TeraRanger Evo Swipe to a computer and select the corresponding USB
port (click “R” button to refresh the port list). Please configure the software with the
following parameters:
Baud rate : 115200 bit/s
Data bits : 8
Parity bit : None
Stop bit : 1
For easier data reading, select the “LF” option from the “Newline at” drop-down field.
See Figure 5 below for visual instructions.

10/14
Once the USB port is selected and the parameters correctly set, click on the “Connect”
button. The gesture recognition data will now appear in the “Received data” box (see
Figure 6).
Figure 6 - Data stream on HTerm software
3.2.2. Mac OS
When using a Mac OS it is also possible to use any terminal emulation software for data
display. Terabee often works with and suggests using the Coolterm software. Please
follow the provided link to download the software file(https://freeware.the-meiers.org/).
Next, double click on the “CoolTermMac.dmg” file and then on the Coolterm icon.
Connect the TeraRanger Evo Swipe to a computer and click the “Options” button. Select
the corresponding USB port (click “Re-Scan Serial Ports” button to refresh the port list).
Please configure the software with the following parameters:
Baud rate : 115200 bit/s
Data bits : 8
Parity bit : None
Stop bit : 1

4. USB operation
4.1. Use case
4.1.1. Sensor Orientation
The connector of the USB backboard should be placed on the right, Figure 8 illustrates
the correct orientation of the TeraRanger Evo Swipe in order to have a correct reading
of the gesture recognition data during use.
<= USB Connector
Figure 8 - sensor positioning
4.1.2. Sensor Positioning
For optimal gesture recognition, Terabee recommends 3 different positions:
●Person in front of the sensor
Sensor placed in front and in parallel with the user’s body.
●Sensor pointing up with hand swiping
Sensor placed on top of a flat surface, and without an obstacle in front of the sensor.
●Sensor pointing down with hand swiping
For a discreet installation of the TeraRanger Evo Swipe, the sensor is placed beneath a
flat surface, without an obstacle in front of the sensor.

13/14
The users’ body should be more than 0.5 m away from the sensor, with their
hand swiping in the 0.1 m to 0.5 m range of the sensor, to not affect the sensor
behavior and to be out of the sensor field of view.
4.2. Printout
When streaming data using the HTerm software the direction of the swipe is displayed
in ASCII in the form of a 4 to 5 byte newline terminated message ie. left\n or right\n.
Swipe reading : xxxxx
New line character : \n (10 decimal / 0x0A hex)
