Odyssey® Xtreem
Single Soil Moisture Logger
User Manual
Principal of Operation
The soil moisture logger is non contact an measures both the soil moisture an temperature at the
epth the sensor is burie .
The sensor consists of two metal plates connecte to a proprietary oscillator circuit. As the moisture
of the soil seen in the electric fiel between the plates increases, the capacitance also increases
which re uces the frequency of the oscillator. This frequency is then measure by the sensor over a
fixe time perio . The sensor measurement iameter is up to 170mm in soil.
The sensor temperature is measure through a thermal bon to the moisture measurement plates
which are in close proximity to the soil.
The sensor measurements are converte to igital in the sensor an the resultant igital ata is sent
to the O yssey® Xtreem logger at the en of the cable. The logger stores the ata in its memory along
with the time of the measurement.
When uploa ing the ata via Bluetooth to a tablet / phone the soil moisture ata is compensate for
variations ue to soil temperature using the store factory calibration.
Installation
The soil moisture sensor cable must be plugge into the logger. The connector is keye so once this
is line up push the connector in as far as it goes an then rotate the top of the connector until it
locks into place. The sensor shoul not come out when light ownwar pressure is applie to the
sensor connector. Do not pull on the sensor cable.
The black sensor must be fully burie to get the best performance. Excavating a hole is one metho
or for lighter soils it may be possible just to push the sensor into the soil. Never force the sensor into
the soil with a tool.
Installing the Xtract Application
Search Google Play Store or Apple App Store for the O yssey® Xtract application an install as usual.
The application must have access to Bluetooth communications an GPS location services.
In the Settings screen enter your username an passwor provi e by Dataflow Systems.
Press the green SE VE SYNC button to loa the O yssey® logger an configuration(s) from the
Xpert Web Portal.
The latest O yssey® Xtract user manual an other user manuals are available on Xpert once you
have logge in.
Identifying the Logger
By efault the O yssey® Xtreem logger will arrive with its name being a hexi ecimal representation of
its serial number. In the Xtract Application press the View button. Once scanne , the O yssey®

coloure green if it is very close ) is the logger that is closest to the tablet / phone.
Setting Up the Logger
The first time the logger is use , unscrew the top cap an remove the battery insulation isc. All user
configuration is carrie out in the Xpert Web portal. The tablet / phone running the Xtract application
transfers the logge ata from the O yssey® Xtreem logger to the Xpert web portal an transfers the
configuration into the O yssey® Xtreem logger. Using a web browser ( Firefox is preferre ) navigate
to www.xpert.nz, then enter your username an passwor provi e by Dataflow Systems. On the
Map page ( efault ), select Home from the rop own selection box, then select a logger from the
logger selection rop own box. An icon for the selecte logger will isplay on the Map. Click on this
icon an an information box above it will pop up. To locate the icon for the first time, it may be
necessary to zoom the Map out to fin the logger.
Downloa the full O yssey® Xpert user manual from Xpert web portal.
Logger Configuration
1. Select the Logger Config Tab. Enter a Logger Name that will be use to I entify the Logger
from now on. The serial number can be use however this is very long an ifficult to
remember.
2. For most situations use continuous logging. This means once the memory is full it will start
overwriting the ol est ata first. Start an stop times can also be entere .
3. Choose a logging Interval in Hours, Minutes an Secon s. Intervals selecte below 1 minute
will force continuous logging to be isable . At an interval of 30 minutes the logger will not
overwrite ata for more than a year.
4. In the Site box, a some brief location information to help locate the logger in the future. In
the Notes box a any information that may be of use.
5. Select the Time Zone the Logger is eploye at. This is important as it may be ifferent from
the time zone where the ata is viewe .
6. Press the Submit button to apply the Logger Configuration.

2. Choose the Calibration type either percentage of Saturation or Volumetric percentage.
3. Select from one the stan ar soil types in the rop own box. The standard soil types are only
a starting point and these should be changed once the values are known for your soils. If the
soil type is unknown, select the custom option an enter the values for ry soil an the fiel
capacity. Follow the fiel capacity measurement in the section below. For more information on
Soil types see the section below on Soil Types. The Soil Type can be change at any time as
these values only affect the isplaye Soil moisture not the raw values that are store in the
atabase. To see the raw values select the Soil Test option.
4. Enter a wilt point % which is a user efine line that will be isplaye on the chart.
5. If Volumetric Calibration has been selecte , enter the three values, Saturate Soil Weight, Dry
Soil Weight & Saturate Volume.
6. Slope an Offset will be automatically calculate an shown on the profile line in the secon
section. You can also enter your own slope an offset by changing the Calibration Metho
from Calculate to User Define .
7. Press the Submit button to apply the Calibration.
Transfer Configuration to Logger
The configuration will be sent to the logger automatically ( typically less than 10 minutes ) through the
tablet / phone running the Xtract Application. To apply this imme iately, press the 'SE VE SYNC'
button in the Settings screen. Once the button has been presse the time below the button will
isplay the wor 'Never', then once synce , it will change to a vali time.
Select the History screen in the Xtract Application to view the logger name(s) entere for the
O yssey® Xtreem logger(s).
The next time the tablet / phone sees the logger, it will connect to it an automatically apply the
settings.
Soil Types
Soil types can be characterise by the size of its particle. Gravel or stones are larger than 2mm in
size. San ranges from 2mm own to 0.05mm in iameter while Silt ranges from 0.05mm own to
0.002mm in iameter. Clay particles are flat shape ( not roun ) an are less than 0.002mm in size.
Using the soil triangle, scientists have create classes which break the istribution of particle sizes
into 12 categories: clay, san y clay, silty clay, san y clay loam, clay loam,silty clay loam, san , loamy
san , san y loam, loam, silt loam, silt.
Basically the larger the soil particle size is the less moisture the soil can hol .
Dataflow have characterise the soil moisture logger for these 12 types of soil to help in initial setup.
Once you know the ry point an fiel capacity of your soils select the custom to enter these
manually.
Fiel capacity is the amount of water that can be hel in the soil against gravity. The Xtreem logger
system can be use to measure this value.

User Manual
In the calibration tab select the soil type as Soil Test for all levels an press the submit button. We
suggest the logging interval is set to 1 minute for this test.
Place a 250mm iameter cylin er ( a 20 litre bucket with the bottom cut out ) aroun the logger an
fill with water. The water will slowly empty from the bucket into the soil. This may have to be repeate
several times epen ing on the soil type an the epth of the bottom sensor.
Using the Xpert portal select the chart page for this logger. It can be clearly seen that the moisture
value increases soon after the water is applie aroun the logger. The moisture value shoul rise to a
peak value then rop back a small amount an level out. The measure fiel capacity from the chart
page must be multiplie by 100 when entering it into the 'Fiel Cap' box on the Calibration page.
Fin a soil type on the Calibration page where the fiel capacity is similar to the measure fiel
capacity ( x 100 ) an the rypoint value for this soil type shoul be the rypoint nee e . Note the
values entere on this calibration page o not affect the factory calibration of the logger, just the
isplaye an exporte ata. Choose the Custom Soil type from the rop own box an enter the
rypoint value an fiel capacity value.
Volumetric Measurement
There are three more parameters require for Xpert to calculate the parameters to give volumetric
soil moisture percentage.
These measurements are normally carrie out by a qualifie technician following a test Stan ar like
ASTM D2216 there the following is only an overview to ai in the un erstan ing of the process.
Using a soil corer collect a saturate soil sample an place this sample into a plastic bag. The
volume of soil the corer collects is the Saturated Volume.
Accurately weigh the soil sample, this is the Saturated Soil weight .
Dry the soil, this is normally one in an oven over several ays.
Accurately weigh the ry soil, this is the Dry Soil weight.
Calculations
For either Percentage of Saturation or Volumetric Percentage the calculation is the same.
The slope an offset parameters are use as follows to calculate soil moisture.
Soil Moisture (%) =
(( Logger Reading (%)
100 ×Slope)+Offset )×100
For a logger rea ing of 60.00% with calculate scale of 1.4815 an an offset of -0.3704.
(( 60.00
100 ×1.4815)−0.3704)×100
= 51.85%

www.O ysseyDataReco ing.com. As the batteries are non-hazar ous, isposal is with your normal
rubbish. We recommen with temperatures greater than 0ºC to use the Energizer Max E91 with
PowerSeal Technology batteries as these have been teste in our Xtreem pro ucts to give the best
life an are least likely to leak. At 0ºC the battery life is re uce to half of its calculate life an it
further re uces to 1/8th of its life at -20ºC.
For temperatures below 0ºC we recommen Energizer Lithium L91 batteries an these will have a
life of greater than 2 years even at -20ºC. Replace the batteries in the logger in the in icate
orientation in the battery hol er. ( Note the unit will not be amage if the batteries are inserte
incorrectly ). Before replacing the cap check the O-Ring seal is present, clean an free from irt. If
require apply some silicon grease ( available from www.O ysseyDataReco ing.com ). Replace the
cap an tighten by han . Do Not use any tools to tighten the cap.
If the logger is not to be use for more than a year, then remove the batteries to prevent any chance
of leaking.
