LCD Symbol
Description
The battery indicator shows the approximate battery
charge remaining.
This is a signal strength indicator. The more bars, the
stronger the signal between motes. If there is no x
icon next to the signal strength indicator, then the
mote is part of a HOBOnet Wireless Sensor Network.
An empty signal strength icon plus the x icon
indicates that the mote is not currently part of a
network. See Adding the Mote to the HOBOnet
Wireless Sensor Network for details on how to add a
mote to the network.
When the mote is in the process of joining a
network, the signal strength icon will blink and then
the bars in the icon will cycle from left to right. The x
icon will blink during the last step in the network
registration process (see Adding the Mote to the
HOBOnet Wireless Sensor Network for details).
This indicates a problem with the sensor itself (the
mote is operational). Check the sensor and make any
adjustments to it as needed. Contact Onset
Technical Support if the problem persists.
Sensor Components and Operation
The sensor measures soil moisture, temperature, and EC of soil
using stainless steel needles. As shown in the following
diagram, the sensor measures soil moisture between Needle 1
and Needle 2 and measures EC between Needle 2 and Needle
3. Temperature is measured with an embedded thermistor.
A ferrite core positioned on the sensor cable 7.6 cm (3
inches) away from the sensor head is used to isolate the
sensor from any interferences in the system. This
mitigates any potential noise from the system on the
measured sensor data.
Important: Do not attach anything to the section of the
cable between the sensor head and the ferrite core as
this may influence the measurements.
The VWC measurement sensitivity is contained within a 1,010
mL volume roughly depicted in the following VFW volume of
influence figure.
Adding the Mote to the HOBOnet Wireless
Sensor Network
The mote must join a HOBOnet Wireless Sensor Network
before it can begin measuring soil moisture and transmitting
data. This requires accessing the station and the mote at the
same time so it is recommended that you complete these steps
before deploying the mote.
Important: If you are setting up a new station, follow the
instructions in the station quick start before setting up this
mote (go to www.onsetcomp.com/support/manuals/24380-
man-rx2105-rx2106-qsg for RX2105 and RX2106 stations or go
to www.onsetcomp.com/support/manuals/18254-MAN-QSG-
RX3000 for RX3000 stations).
To add a mote to the network:
1. If the LCD is blank on the station, press any button to wake
it up.
2. Press the Select button once (which shows the number of
smart sensors installed) and then press it again to switch to
the module with the manager (module 2 on RX2105 or

3. Press the Search button (the magnifying glass). The
magnifying glass icon will blink while the station is in search
mode.
4. Open the mote door and install the batteries if you have not
already done so.
5. Press the button on the mote for 3 seconds. The signal
strength icon will flash and then cycle.
6. Watch the LCD on the mote.
The green LED blinks quickly while the mote searches for a
network to join and then blinks slowly while it completes
the network registration. Once the mote has finished
joining the network, the green LED turns off and the blue
LED then blinks indefinitely while the mote is part of the
network.
Note: If the mote cannot find the network or has trouble
remaining connected during this process, make sure the
mote is in a vertical, upright position and within range of
the station.
7. Press the Search button (the magnifying glass) on the
station to stop searching for motes.
If you added more than one more mote to the network, then
the total channel count on the station LCD for the manager
module will represent all measurement channels plus a battery
channel for each mote in the network.
Sensor measurements will be recorded at the logging interval
specified in HOBOlink, transmitted to the station, and uploaded
to HOBOlink at the next connection interval (readout). Use
HOBOlink to monitor mote status and health. If a mote is
temporarily offline, any logged data is saved until it is back
online. In addition, if a mote is offline for 30 minutes, the
station will automatically connect to HOBOlink and report the
mote as missing. Once the mote is back online, any logged data
will be uploaded the next time the station connects to
HOBOlink.
See the HOBOlink Help for details on how to change the logging
and connection intervals, view data, check mote status, add the
mote to a map, and more.
Installing the Sensor
There are two installation methods for installing the sensor:
borehole or trench.
Borehole Installation Method
This method allows for a profile of soil moisture sensors to be
installed at different depths within a single augered borehole,
thereby minimizing soil disturbance at the measurement site. A
10-cm (4-inch) borehole is augered vertically at the
measurement location. You can then carefully insert and place
the sensor by hand or buy or rent the Borehole Installation Tool
from Meter (recommended for depths greater than 50 cm (19.7
inches). Email Meter at [email protected] (North America)
or [email protected] (Europe) for details on buying
or renting the tool.
If you are installing the sensor without the Borehole Installation
Tool, look down the hole with a flashlight, reach in with the

sensor and push it into to the side of the undisturbed soil. Look
down the hole and make sure it is firmly seated. You can also
consider attaching the sensor to PVC piping or similar material
to aid in placing the sensor. You can then use the PVC as a lever
to assist with pushing the sensor into the undisturbed soil.
Trench Installation Method
This method is best for shallow installations at less than 40 cm
(15.7 inches). This requires digging a trench with a shovel,
excavator, or other tool to the depth of the deepest installed
sensor (if installing more than one in the measurement
location). For deep installations, this may require a large trench.
The sensor is then installed carefully by hand into the
undisturbed soil of the trench sidewall. The trench is carefully
backfilled to preserve the bulk density of the soil and avoid
dislodging the installed sensor by accidentally snagging the
ferrite core.
Sensor Installation Guidelines
Before installing the sensor, follow these guidelines:
•Test the sensor functionality and accuracy using the TEROS
verification clip. Refer to the TEROS verification clip
documentation for details on operation and expected
readings. If you do not have a verification clip, you can
perform a rough check of sensor functionality in air and
water. The sensor will produce readings of ~0.70 m3/m3in
water and ~0.003 m3/m3in air. Use HOBOlink to export or
view the data for your test.
•When creating the hole to install the sensor, avoid
interfering objects. Installation near large metal objects
can affect the sensor function and distort readings. Large
objects like roots or rocks could potentially bend the
needles.
•The sensor may be positioned in any direction. However,
there is less restriction to water flow when the sensor
body is placed in a vertical position as shown below. A
vertical position will also integrate more soil depth into
the soil moisture measurement. Installing the sensor with
the sensor body in a horizontal position will provide
measurements at a more discreet depth.
•Do not touch the sensor needles with an ungloved hand or
bring them in contact with any source of oil or other
nonconducting residue. If the sensor needles are
contaminated with oils from contact with skin or another
source, follow the instructions in the Maintenance section
for cleaning the needles before installing the sensor.
•Avoid any metal located between the sensor and the
ferrite core because it can interfere with VWC
measurements.
•When installing sensors in rocky soils, use care to avoid
bending sensor needles.
•Minimize air gaps around the sensor. Air gaps around the
sensor needles will result in low readings of soil moisture.
•When backfilling the hole, be careful not to snag the
ferrite core on the sensor cable.
•Secure the sensor cable to the mounting pole or tripod
with cable ties.
•Use conduit to protect the cable against damage from
animals, lawn mowers, exposure to chemicals, etc.
Sensor Installation Instructions
1. Auger or dig a hole to the desired sensor depth.
2. Carefully insert the sensor in the hole and push the sensor
so that the needles are inserted into the undisturbed side of
the soil. Check that the sensor is firmly seated.
3. Secure the cable to the mounting pole or tripod and install
flexible conduit before backfilling the hole.
4. Carefully return the soil to the hole, packing it back to its
native bulk density. Do not hit the ferrite core as this could
potentially pull the sensor out of the soil.
Mounting and Positioning the Mote
•Mount the mote to a mast or pipe using cable ties or affix
the mote to a wooden post or flat surface with screws.
Insert the cable ties or screws through the holes on the
mounting tabs.
•Consider using plastic poles such as PVC to mount the
mote as certain types of metal could decrease signal
strength.
•Make sure the mote remains in a vertical position once it
is placed in its deployment location for optimal network
communications.
•Make sure the mote door is closed, with both latches fully
locked to ensure a watertight seal.
•Consider using a 3/16 inch padlock to restrict access to the
mote. With the mote door closed, hook a padlock through
the eyelet on the right side of the door and lock it.
•Position the mote towards the sun, making sure the solar
panel is oriented so that it receives optimal sunlight
throughout each season. It may be necessary to
periodically adjust the mote position as the path of the
sunlight changes throughout the year or if tree and leaf
growth alters the amount of sunlight reaching the solar
panel.
•Make sure the mote is mounted a minimum of 1.8 m (6 ft)
from the ground or vegetation to help maximize distance
and signal strength.

RXW TEROS-12 Soil Moisture EC Temp Sensor (RXW-T12-xxx) Manual
1-800-LOGGERS 6 www.onsetcomp.com
•Place the mote so there is full line of sight with the next
mote. If there is an obstruction between two sensor
motes or between the sensor mote and the manager, then
use a repeater mounted on the obstruction. For example,
if there is a hill between the sensor mote and the
manager, place a repeater at the top of the hill between
the sensor mote and the manager.
•There should not be more than five motes in any direction
at their maximum transmission range from the manager.
Data logged by a wireless sensor must travel or “hop”
across the wireless network from one mote to the next
until it ultimately reaches the manager connected to the
station. To make sure the data can successfully travel
across the network, the mote should not be more than
five hops away from the manager.
•The HOBOnet Wireless Sensor Network can support a
maximum of 50 motes.
•Use a #4-40 screw to attach a ground wire to the port on
the back of the mote if you are deploying the mote in a
location where lightning is a concern.
Maintenance
If the sensor needles become contaminated with oils from
contact with skin or another source, it is necessary to clean the
needles to ensure accurate EC readings in salty soils with bulk
EC greater than 10 dS/m.
1. Clean each needle using a mild detergent, such as liquid
dish soap and a nonabrasive sponge or cloth. Avoid
detergents that contain lotions or moisturizers.
2. Rinse the sensor and needles thoroughly with tap or
deionized (DI) water. Do not touch the needles with an
ungloved hand or bring them in contact with any source of
oil or other nonconducting residue.
The mote is designed for outdoor use, but should be inspected
periodically. When inspecting the mote, do the following:
•Verify the mote is free of visible damage or cracks.
•Make sure the mote is clean. Wipe off any dust or grime
with a damp cloth.
•Wipe off any water before opening the mote.
•Make sure the interior seal is intact and the latches are
fully locked when the mote door is closed.
Troubleshooting
If the sensor readings are too low or slightly negative, check for
air gaps around the sensor needles. These could be produced
below the surface of the substrate when the needle contacts a
large piece of material and pushes it out of the way, or if the
sensor is not inserted perfectly linearly.
If the sensor readings are too high, make sure the media was
not packed excessively or insufficiently during sensor
installation. Higher density can cause the sensor readings to be
elevated.
Updating Mote Firmware
If a new firmware version is available for the mote, use
HOBOlink to download the file to your computer.
5. In HOBOlink, go to Devices, then RX Devices, and click your
station name.
6. On the station page, click Overview and scroll down to
Device Information.
7. Click the Wireless tab. This icon appears next to the
mote if there is a new version of firmware available.
8. Click the firmware upgrade link. Click Download and
save the firmware .bin file to your computer.
9. Connect the mote to the computer with a USB cable (open
the mote door and use the USB port to the right of the
LCD). The blue LED is illuminated while connected.
10. The mote appears as a new storage device in the
computer’s file storage manager. Copy the downloaded
firmware file to the new storage device (the mote). The
blue LED will blink slowly while the file is copying.
11. After the file is copied to the mote, the LED will stop
blinking and remain a steady blue. Eject the storage device
from the computer and disconnect the cable from the
mote. The firmware installation process will begin
automatically on the mote. The blue LED will blink rapidly
while the firmware is installed. Once the firmware
installation is complete, the LCD symbols return and the
mote will automatically rejoin the network.
Notes:
•Mac® users: A message may appear indicating the disk
has not ejected properly when disconnecting the mote
from the computer. The mote is operational and you can
ignore the message.
•If the blue LED turns off abruptly while copying the file or
installing the firmware, a problem has occurred. Contact
Onset Technical Support for help.
Battery Information
The mote uses two 1.2 V rechargeable NiMH batteries, charged
by the built-in solar panel. The quality and quantity of solar
light can affect whether the battery is sufficiently charged to
last through the night and cloudy periods. Make sure the mote
is placed in a location that will receive several hours of sunlight
each day. If the mote does not receive enough sunlight to
recharge the batteries, the battery life is estimated at 3–4
months. When batteries are regularly recharged, expected
battery life is estimated at 3–5 years. Battery life varies based
on the ambient temperature where the mote is deployed, the
logging interval, the number of tripped alarms, and other
factors. Deployments in extremely cold or hot temperatures
can impact battery life. Estimates are not guaranteed due to
uncertainties in initial battery conditions and operating
environment.
Mote operation will stop when battery voltage drops to 1.8 V.
Mote operation will return if the battery recharges to 2.3 V. If
the batteries are unable to be recharged, replace them with
fresh rechargeable batteries. Note: if you install used
rechargeable batteries that together are less than 2.3 V, the
mote will not resume operation.
To replace rechargeable batteries:
1. Open the mote door.
2. Remove the old batteries and install fresh ones observing
polarity.

1-800-LOGGERS 7 www.onsetcomp.com
3. Make sure the solar panel cable is plugged in.
The mote contacts the network once the new batteries are
installed. The green LED blinks quickly while the mote searches
for a network to join and then blinks slowly while it completes
the network registration. Once the mote has finished joining
the network, the green LED turns off and the blue LED then
blinks indefinitely while the mote is part of the network.
Lithium Batteries
You can use two 1.5 V lithium batteries (HWSB-LI) for operation
at the extreme ends of the mote operating range. Lithium
battery life is an estimated at 1 year, but varies based on the
ambient temperature where the mote is deployed, the logging
interval, the number of tripped alarms, and other factors.
Estimates are not guaranteed due to uncertainties in initial
battery conditions and operating environment. When using
lithium batteries, you must disconnect the solar panel cable
because the batteries will not be recharged.
To install lithium batteries:
1. Open the mote door.
2. Remove any old batteries and install the new ones
observing polarity.
3. Push in the side tab of the solar panel cable connector and
pull the connector out of the cable port.
4. Place the connector in the slot on the inside of the mote
door. Make sure the solar panel cables are tucked inside the
door so that they do not interfere with the interior seal
when the mote is closed.
The mote contacts the network once the new batteries are
installed. The green LED blinks quickly while the mote searches
for a network to join and then blinks slowly while it completes
the network registration. Once the mote has finished joining
the network, the green LED turns off and the blue LED then
blinks indefinitely while the mote is part of the network.
WARNING: Do not cut open, incinerate, heat above 85°C
(185°F), or recharge the lithium batteries. The batteries may
explode if the mote is exposed to extreme heat or conditions
that could damage or destroy the battery cases. Do not mix
battery types, either by chemistry or age; batteries may rupture
or explode. Do not dispose of the logger or batteries in fire. Do
not expose the contents of the batteries to water. Dispose of
the batteries according to local regulations for lithium
batteries.
