▪
Note: ODR needs to be increased when connecting additional sensors as it requires more data bandwidth.
•
Device Settings
o
COM Port:
Specify com port in case multiple hardware boards are connected.
o
ODR:
Time interval to periodically trigger the sensor. Reducing ODR increases the data bandwidth requirement to
transfer data from sensor to host.
o
Decimation:
Decimate IQ data or magnitude streamed from the sensor.
o
Max range in sample:
Number of IQ samples to acquire.
3.3.2 Settings: Sensor height from floor (Auto Configurations)
To use auto configurations set from validation data collected from different surface types, only the floor height value needs to be
inputted. All mounting requirements need to be met and the floor distance needs to be known. For setting custom parameters and
refining the tuning parameters, see
Section 3.3.3
.
Steps:
1.
Mount the module to the desired location with the horn/housing facing downward to the floor surface. The sensor must be
facing the floor surface with no tilt or reflective surroundings. For more information on module mounting, refer to
Section
2.
In the unpacked folder (RoboFloor_vX.X.X.exe) and in the GUI folder, open
‘Gui
-demo-robofloor-
x.x.x’
.
3.
Click the settings icon (
) to input settings.
4.
For auto-configuration, only e
dit the “Sensor Height” value in the settings between 2.5
-6cm (25-60mm). This is the distance
from the acoustic horn/housing bottom surface to the surface.
a.
The default is set to 35mm. All custom parameters are disregarded (in red).
b.
The
‘Sensor Height’
value corresponds to the height that the CH101 sensor is set on the hardware relative to the
surface.
c.
Settings can be saved to a .json file. This will be saved in the GUI folder. Loading the file will overwrite the current
settings to the saved .json file. The .json file can be opened in a notepad or text application to modify the
parameters.

Hit ‘OK’ to save settings for current run. Then
click
‘Connect’ to display real
-time outputs.
