WILSEN.sonic.distance
The figure below illustrates the sequence of measurement data acquisition and data evaluation
of the WILSEN.sonic.distance in conjunction with the triggers that trigger them.

Measurement Sequence
The ultrasonic measurement always consists of the actual measured value acquisition by
sending out an ultrasound package and measuring the echo delay time to detect the distance
to the object in the sensing range.
Optionally, you can set a measurement sequence instead of a single measurement, i.e., a
sequence of several individual measurements at defined time intervals. These measurements
are then evaluated, e.g., on the basis of determining the average and optionally further param-
eters, and calculated to provide a result.
Alternatively or in addition, the recorded data can optionally be filtered using post-processing
filters, for example to further stabilize or optimize the subsequently output data for a specific
application.
Data Transfer
The ultrasound measurement sequence described above, with any optionally selected compo-
nents, is triggered by the expiration of a set "LoRa transmission interval" (see chapter 7.5).
The value determined from the ultrasonic measurement (distance in mm) is then transferred
alongside more information with the "Payload 1."
Alternatively or in addition, the same set ultrasonic measurement sequence is triggered by the
expiration of the "GPS acquisition interval" (see chapter 7.4). In this case, the GPS position is
also determined.
The value determined from the ultrasonic measurement (distance in mm) is then transferred
alongside the acquired GPS position and more information with the "Payload 2."
