The sensors are watertight and can also be buried in the ground. For the UMP-1-BT version,
a maximum depth of 50 cm to be able to receive the Bluetooth signal. Depending on the soil
type, the water content and the Bluetooth receiver the maximum installation depth may
vary. Prior to installing several sensors deeper than 50 cm it is recommended to test the
operation of the data transmission with a single sensor.

Operation
To guarantee an effective use the UMP-1 is available in two different types. Standard as
UMP-1 BT for installation in the field at different, maybe even hard to reach sites. And as
UMP-1 BTim for measurement campaigns with many single measurements spread over a
wide area. With a diameter of 5 mm the pins are bigger but also more robust than the pins
of the standard type. The guidance of the pins additionally prevents damages of the pins
during penetration of the soil. The extension of the probe with handle bar and smartphone
bracket enables fast work for taking many single measurements in a row.
Despite the different design the two probes hardly vary in the basics of operation just in the
practical adjustment to their core tasks.
By pressing the button on top of the
sensor briefly the sensor is switched on.
The red lighted status-LED shows the
operating state of the sensor. After
completion of the measurement/test
series the sensor should be switched off
by pressing the button long (ca. 2s) to
save power. Then the LED is no longer
lighted. Only in the switched on state a
Bluetooth connection can be
established.
Especially for fast done single measurements and anew penetration of the sensor into
the soil each time special importance needs to be attached to the installation.
•
For the measurement the antennas need to be completely in the soil.
•
There must not be produced a gap between antenna and soil (for example by
movement of the sensor).
•
The antennas have to be parallel and undamaged. The correct position of the
antennas to each other is crucial for the accuracy of the measurement results.
•
Be careful pushing the antennas into the soil. In case of hindrances don´t push
further with more force but rather penetrate again at another spot. For very rigid soil
better pre-drill.
