2.3 Power ON/OFF
The sensor is shipped completely off to prevent battery consumption during storage. It is therefore
necessary to carry out a first power-on prior to commissioning.
To power on the sensor: lay the magnet at the bottom of the provided tool into the area shown in the
figure:

Successful power on is signaled by the flashing of the 3 LEDs.
In case of long period of inactivity, if necessary, is possible to shut-off again the sensor to prevent
battery consumption, via downlink or with LoRa Tool App:

Once provisioned on a LoRaWAN® network, the device sends the distance & timestamp to the server
via uplink.
3.1 Level settings
Level measurements are carried out according to few parameter settings. A target over the defined
range cannot be detected. Read and write of parameters can be done using LoRaTool App. They have
a default value and can be modified to be tailored on the specific use case.
Meaning of parameters is related to following diagram. The “REFERENCE” (distance=0mm) is the top
surface of the sensor:

3.1.1 Start [mm]
Starting point of the measurement (in mm from “REFERENCE” point).
Values can be set from 140 to 1360:

Default: 140
A target within the “Start [mm]” distance will result at a “Start” distance.
The “Start [mm]” value is also related to other level parameters. Contact enginko in case of
assistance.
