The IRROmesh System is
a wireless mesh network
data collection system that
automatically records soil
moisture and other sensor data.
This data can be viewed in real time on the WEB or
downloaded in the field. Manually collected data can
also be uploaded to the WEB. This manual provides
detailed instructions for setup and installation.
Planning Your Network Layout
Plan the network layout ahead of time, before
installing any hardware. Determine the areas needed
to monitor soil moisture. Careful selection of mesh
radio Node locations is also critical to establishing good
communication of data. Consequently, there is a dual
requirement of “where the Sensors should be located”
and “where the Nodes should be located.” Determine
the best layout to satisfy both requirements.
Map out your field and indicate all areas that require
monitoring, then identify possible Node locations that
correspond to each area being monitored. Determine if
the range and placement of Nodes will establish a
good communication network. It may be necessary to
add Nodes, with or without sensors, to relay the data
transmission in acceptable path lengths and offset
angles. Mapping out the potential Node/Sensor
locations to verify that distances are acceptable and
potential obstructions are avoided will make the
physical deployment of the hardware much easier.
Avoid installation near areas with potentially strong
radio signal interference. Areas such as airports, cell
towers, etc. can pose significant interference.
For best communication:
A – The Base Node should be located near the
network’s center. Install the Base higher than the Nodes
reporting directly to it.
(see Figure 1)
B – Relay/End Nodes,
should be at least 10 ft
(3m) above ground and a minimum of 5 ft (1.5m)
above the mature crop canopy to ensure clearline-of-sight
(CLoS)
.
(see Figure 1)
The ideal radio
wave pathway is not simply a single straight line
between two points, but rather, a three
dimensional oval-shaped zone. Anything that
protrudes into this zone from the sides will
reduce the radio range. The operating range will also be
reduced if the Nodes are not installed at adequate
heights.
(see Figures 2 & 3)
C – Relay Nodes form the backbone of the mesh and
‘relay’ data from the Nodes reporting to them towards
the Base. It is important to establish a ‘grid’ layout so
that multiple paths exist between Relay Nodes for data
to flow to the Base. End Nodes only send their data to
a nearby Relay Node or to the Base and should be

enclosure and slide the switch on top of the
board to the ‘ON’ position. Close the cover and
temporarily position the Base with both solar panels
facing the sun. It will take the longest to charge since it
has the largest capacitor power supply. In full sun
conditions, it should be exposed for about 4 hours to fully
charge. In partly sunny conditions, it will take longer.
Whatever the conditions, wait until the bottom light is
flashing, which indicates it is fully charged and seeking
communication.
(see Figure 5)
Once the Base is fully charged, slide the power
switch inside its enclosure to the ‘OFF’ position and
place the black plastic bag back over the Node
to cover the solar panels. Move the Base at
least 30 ft (9m) away from the area where
Nodes will be charging. This will isolate the
Base so Relay/End Nodes cannot
inadvertently become associated
with it before they are ready.
Charging the Nodes
Minutes before Installation:
Charge the Nodes (975NE and 975NR) by
exposing their solar panels to full sunlight for at least
fifteen minutes, slightly longer in less than full sun
conditions.
Be sure all Nodes are at least 30 ft (9m)
away from any operating Base before proceeding.
Remove the black plastic bag from each Node that
will be used with the current Base and temporarily
support the Node in an upright position with both solar
panels facing the sun. Wait until the top two lights,
RED and YELLOW, are flashing before proceeding.
(see Figure 5)
Associating the Nodes and
Data Collection Devices to the Base
Record and keep your Base ID
and PIN in a safe place.
All Nodes and data collection devices must be
associated with the current Base. To provide security of
your data and network, Relay/End Nodes and data
collection devices are associated with one specific
placed at the extremities of the system or
located so as to provide in-fill near relaying
Nodes.
(see Figure 4)
D –
There is a limitation to the number of
Nodes that can be in a ‘path’ and how many
total ‘paths’ can feed to the Base. If all the
data from several Nodes has to route
through a single Node along a path, then a
‘choking point’ is created, diminishing the distance that
Node can transmit and reducing reliability of the system.
– The maximum total number of Nodes = 20
– The maximum number of Relay Nodes = 12
– The maximum number of End Nodes
per Relay = 3
– The maximum number of “hops”
between Relay Nodes = 8
– The maximum paths to the Base = 4
Relay Nodes should be no more than 800 ft (244m)
to 1000 ft (305m) apart (closer together as you get
nearer to the Base). End Nodes can be up to 1200 ft
(366m) from a Relay Node or the Base.
E – Changing weather and ‘radio-noise’ conditions will
affect range. If the installed distance between Nodes
exceeds the suggested range, you may experience
intermittent reporting. Nodes log data even during
times when the network appears to be ‘down.’ Data
collected during such intervals will be transmitted once
communication resumes. During daylight, while
charging, Nodes read their Sensors every 30 minutes
and synchronize with the network frequently. When
sunlight is diminished, Nodes slowly discharge, read
their sensors every 30 minutes and only synchronize
with the network hourly. When communicating, Nodes
are awake and their lights will be flashing. When
between communication cycles, they are “asleep” and
lights will be off.
System Configurations
Three hardware combinations allow different ways of
retrieving data. Installation and operational differences
occur depending on which hardware combination you
use. Be sure to follow the applicable instructions for
your specific hardware combination.
Charging and Associating
Base and Nodes
See instructions in the Quick Start Guide to charge
and associate the Base and Nodes together.
Charging the Base

Remove the Base Node (975B) from the black
plastic bag, open the cover of the capacitor

Base and will not send data to any other Base. If a
Base is lost, you will need to order a new one,
specifying the ID and PIN numbers of the original unit.
When all devices to be associated to the Base are
powered or fully charged they should have the two top
lights, RED and YELLOW, flashing. Place no more
than 10 Nodes at a time, and the data collection device,
in upright positions in close proximity to one another.
Place the still un-powered Base in the center of the
components, making all devices no more than 2 ft (60
cm) from the Base. Uncover the Base solar panels and
slide the power switch inside the capacitor housing to
the ‘ON’ position. Wait until all devices have become
associated, indicated by their lights changing to
flashing GREEN only. (This should take about 15
minutes.)
(see Figure 6)
If associating a large number of Nodes, do so in
batches of 8-10 at a time. Once each batch is done,
turn off the Base, move the first batch of Nodes far
enough away (3000'+ [915 m]) so the Base can’t ‘hear’
them anymore, then restart the Base and associate the
next batch. Adata collection device (Logger, PC Link or
Cellular Gateway) is counted as a Node for
purposes of association.
NOTE: Always associate components in an
upright position. If any device was not fully
charged the system may go into sleep mode.
If this occurs some of the units will have no
lights on. Leave everything in place for an hour
and when it wakes up it should associate with the
remaining devices. Confirm that each device is flashing
GREEN before proceeding. When the whole system is
associated slide the Base power switch to ‘OFF’ and
cover the solar panels. (This helps avoid any Nodes
making routing associations with other Nodes that they
may not be near once installed in the field.)
Data collection devices have their own power
supplies and must be powered up in order to associate
with the Base. See instructions for your device on
pages 4 to 5.
Installation
BASE: At the pre-determined Base location, uncover
the solar panels and slide the switch inside the Base
enclosure to the ‘ON’ position. Mount on any sturdy
post or pole using supplied mounting brackets. Rigid
metallic or wooden poles will provide the best wind and
heat resistance. Plastic pipe is not recommended as it
will soften in the heat and tend to bend and sway with
the breeze. A recommended practice is to install a
short post in the ground and sleeve a hollow,
lightweight mounting pole over the top of it. This allows
you to remove the pole as needed for maintenance or
cultural practices. Base enclosures are rainproof but
should always be mounted vertically.
NODES: Nodes can now be installed at their
predetermined monitoring locations. Begin with
locations closest to the Base, which should
be 800 ft (244m) or less, then work
outwards towards the ends of the network.
For optimal range, install the mounting pole
and orient the attached Node so that the
antenna face (red board above the solar
panels) is within 150° of the other Nodes it
‘talks’ to. Depending on sunlight conditions,
it may take up to 24 hours for all Nodes to
join the network. An East-West orientation
of the Node solar panels will give the best sun
exposure
(see Figure 7).
When a Node joins it will be displayed on the WEB
portal by its ID number (with PC Link or Cell Gateway
systems). If after 24 hours all Nodes have not joined,
the mesh can be reset by cycling power to the Base
(see page 8).
As with the Base, any sturdy post or pole can be
used to mount the Nodes since they are small and
lightweight. A plastic 3/4'' female threaded bushing can
be adapted to the top of the pole to accommodate the
Node which is then threaded into the bushing. This
type of pole will provide the best wind and heat
resistance. Arecommended practice is to install a short
post in the ground and sleeve a hollow, lightweight
mounting pole over the top of it. This allows removal of
the pole as needed. The 25 ft (7.62m) cable
extending from each Node should be routed
3
•

•

through the mounting pole and brought out at or near
the bottom so that the wires can be connected to the
sensors. DO NOT connect the sensors yet. Be sure to
have the cable exit the pole above the level of the inner
post to avoid wire damage. Also leave an adequate
length of cable exposed to allow the pole to be lifted off
of the inner post without disconnecting from the sensor
wires. The use of a small valve box or junction box will
protect the wire splices and make them easy to find
should anything need to be disconnected in the future.
Node cases are rainproof but should always be
mounted vertically. The components inside the cases
are conformal coated for moisture protection but
should not be directly exposed to water.
Use the form on page 10 to record ID numbers,
located on the label under each Node’s clear cover,
and a reference name for its location. This information
will be needed later when you configure your system in
the WEB portal or WaterGraph Software. Note that
these numbers are comprised of only 0 through 9 and
letters A through F. Be sure to record them accurately.
The geographic reference (latitude/longitude in
decimal degree format) for each Node can be input
during set-up to enable Nodes to display in the portal’s
mapping feature (when using SensMitWeb).
Off-Season Shut-Down:
To properly shut a system
down during the off-season, slide the power switch
inside the Base housing to ‘OFF’ and cover the solar
panels. It is best to remove the Base from the field
entirely. If the Base is left operational during nonreporting periods, it will still accumulate data then upload
it once connectivity is re-established next season,
possibly incurring additional data usage charges.
SENSORS:
Once all Nodes are in place and the
network is functioning properly, the sensors can be
installed and wired to the Nodes. Refer to the
‘Connecting to WATERMARK Sensors’ section on
page 6, and the color reference wiring instructions on
page 9. When in place, configure them to display
using your own alphanumeric descriptive references.
Data Collection Options
LOGGER — 975L
Data is collected from the Base by a stationary
Logger in the field and retrieved manually
with a laptop computer. A free download
of 975L WaterGraph Software is provided
to retrieve, view and graph data.
NOTE: The Logger is used to batch
download data but cannot be used to
‘stream’ data.
Charging and Associating the Logger:
The Logger is
powered by internal super capacitors that are charged
in full sunlight (just like the Base). Slide the power
switch inside the enclosure to the ‘ON’ position, remove
the black bag that covers the solar panels and include
the Logger when charging and associating the Base
and Nodes as described on page 2.
Installation of the Logger:
The Logger must be
mounted in the field with fully charged capacitors and its
power switch in the ‘ON’ position within 400’ (122 m) of
the Base, though it is usually mounted on the same
pole. Mount the Logger, like the Base, on any sturdy
post or pole using supplied mounting brackets, as
described on page 3. (
Installation – Base).
Data Collection with a Logger: 975L software
available from the IRROMETER website at
www.IRROMETER.com/download/975-DL.exe
and running on a Windows®OS laptop is necessary for
data download and display. The Logger must be fully
charged and associated before connecting to the
computer with the 975L software for the first time. The
saved data file can then be opened for display with the
graphing program included in the 975L software or
uploaded to SensMitWeb for later access, archiving
and sharing if a subscription is purchased.
(See the
‘IRROmesh Logger User Manual’ that accompanies
each Logger purchase, for detailed Logger instructions.)
Off-Season Shut-Down of the Logger:
Slide the power
switch inside the housing to ‘OFF’ and cover the solar
panels. Remove the Logger from the field (optional).
PC LINK — 975P
Data is automatically and continuously ‘streamed’ to
the WEB using your computer’s active Internet
connection as long as the computer is on and running
the SenMitPath software. The PC Link connects to your
computer via USB cable and is required to be within
400' (122 m) of the Base. (Range is dependent on what
type of structure the signal transmits through.) Data is
viewed and stored on the WEB.
(Subscription required)
Charging and Associating the PC Link: The PC Link
must be plugged in to an active computer or any USB
socketed power source to supply its power. Once fully
charged, it will hold the charge long enough to be

associated to the fully charged Base outside. Take the
PC Link to within 2' of the Base and wait for the green
light on the PC Link to flash – indicating association
when the system is awake. This will typically take
about 15 minutes.
Installation of the PC Link: First download
SensMitPath software to your Windows
®
OS
computer from
http://www.IRROMETER.com/download/
sensmit_installer.exe
The entire SensMitPath software package is
available through this link or on the IRROMETER
Products webpage under Data Loggers / 975 Wireless
Mesh System / SensMitPath Installer. Downloading
SensMitPath from the IRROMETER web site ensures
you get the program designed for the IRROmesh
firmware version you purchased. Install the program
with administrative privileges. You may need to allow
SensMitPath access through your anti-virus software
in order to access the Internet. Once the program icon
appears on your desktop, double-click to open the
software. Make sure the numerical universal time
indicated at the bottom left of the dialogue box is visible
and updating. If not, with some versions of Windows
®
,
you will need to restart your computer after installing
S
ensMitPath. Make sure the software is always
running and, if you are streaming real-time, that the
computer you are using has all its ‘sleep’ and ‘rest’
functions disabled. If your computer turns off/sleeps,
the data flow will stop. Placing SensMitPath on your
Start Menu will enable the application to restart
automatically in the event of a computer reboot.
Plug the PC Link into the host computer by its
supplied USB cable. The Base signal will travel to it
through non-metallic walls and windows, but range is
less than with outdoor device options. The host
computer must remain turned on and online in order to
continuously stream data. Data can be viewed on any
WEB enabled computer, smartphone or tablet device.
(see Figure 8)
Data Collection with a PC Link: First activate your
system at
www.SensMitWeb.com and become a
subscriber
(see ‘Subscription Registration’ on page 6).
Additional information regarding the software is
available on the SensMitWeb.com ‘Resources’ page.
When running, this utility detects your USB connection
and automatically connects to the PC Link. This
enables any data from your network to upload to
SensMitWeb. Once you have completed registration,
you will be able to view your Nodes and confirm that
the network is operating properly. You will also be able
to access a host of diagnostic features.
Off-Season Shut-Down of the PC Link: Unplug the
PC Link from the computer and turn off the
SensMitPath software.
CELLULAR GATEWAY — 975G-BP
Data is automatically transferred to the WEB by the
Cellular Gateway, where it is viewed and stored.
(Subscription required)
NOTE: Cellular data coverage must be available at the
gateway location.
Charging and Associating the Cellular Gateway:
The Cellular Gateway is powered by its supplied solar
rechargeable battery pack and will be operational
when both battery terminals are connected.
(Units are
shipped with one battery terminal disconnected for
safety.)
To associate, include the Cellular Gateway
when charging and associating the Base and Nodes as
described on page 2.
Installation of the Cellular Gateway: The Cellular
Gateway and accompanying Solar Recharging Battery
Pack can be installed in the field at the Base location,
usually on the same mounting pole or up to 400' (122
m) from the Base. A minimum clearance distance of 3
ft (1m) should be maintained between the Base and
the Cellular Gateway. Mount the Cellular Gateway, like
the Base, on any sturdy post or pole using supplied
mounting brackets, as described on page 3.
If using the same pole as the Base, mount the Base
at the top of the pole, then the Solar Panel, the Cellular
Gateway and finally the Battery Pack, in that order.

SensMitWeb
Subscription Registration
IRROMETER has partnered with iDUS Controls to
provide the WEB storage and display features for data
collected by the IRROmesh system. You must register
and pay a subscription fee online in order to utilize the
features of the WEB portal. All data will be stored within
the portal for current and future access. Data will be
viewable on any WEB enabled computer, Smartphone
or tablet device. To activate your system, go to
www.SensMitWeb.com. Click on the tab ‘Activate
your SensMit Web account here’ (just under the log-in
box) and follow the instructions. Register as the ‘Mesh
Owner’ upon initial set-up if you have the Base ID and
PIN (found on the Node label under the clear cover)
and you will be responsible for subscription fees. This
verifies that you are a certified IRROmesh Owner and
that your data can be accepted into the portal. It will
also start a free one month trial. Base ID and PIN
characters include only numbers 0 to 9 and letters A
to F.
As the Mesh Owner you can grant certain
permissions to ‘Mesh Viewers’ or users but you alone
will be responsible for subscription fees.
NOTE: If you shut down a system during off-seasons
to save expense, the minimum monthly Base fee (and
Cellular Gateway fee if applicable) still applies, in order
to maintain your account.
\Changing a Data Collection Device
If a data collection device needs to be changed (such
as changing from a PC Link to a Cellular Gateway).
1. Un-power the existing device
2. Re-start the Base by switching the power button
‘OFF’, covering the solar panels for a few minutes,
then switching the power back ‘ON’.
3. Associate the new device with the Base.
4. If, after association, data is not being sent, reset the
new device.
(see page 8)
Connecting to WATERMARK Sensors
Follow the wiring color scheme as shown on page 9.
Use waterproof wire connectors.
–
Insert one side of a Node wire pair and one side of
the corresponding sensor wire pair into one
connector. Repeat for the other wire in the Node
pair and the remaining sensor wire with another
connector. One connector per individual Node
wire is needed.
Be sure to INDIVIDUALLY insulate ALL unused
wires. DO NOT leave unused Node wires uninsulated and allowed to corrode, touch each other
or touch the metal pole.
Sensor Installation Guidelines
SENSOR SITE SELECTION — Often more than one
sensor should be placed, at varying depths, in a given
location. For instance, one sensor in the upper portion
of the plant's effective root zone and other sensors
located deeper into the root zone profile. This is
referred to as a ‘sensing station’. It can give a better
representation of the plant’s uptake of water. Be sure to
use enough “sensing stations” – sensing stations every
10-15 acres is a good rule of thumb.
PLACEMENT
Furrow or Flood Irrigation —
Locate sensing stations
about 2/3 the way down the run, just ahead of the
tail or backup water. This is the area where water
penetration is usually the poorest. With tree crops,
locate sensors on the southwest side of the tree (in
the Northern Hemisphere) as this side gets the hot
afternoon sun.
Sprinkler Irrigation — Even though the distribution is
typically more uniform with sprinkler irrigation, there
can be great differences in penetration and holding
capacity due to soil variations, interfaces and
contour. These variation sites make good locations
for sensor stations. With tree crops, locate sensors
at the drip line of the canopy, being sure that they
are not obstructed from the sprinkler’s distribution.
With row crops, locate sensors right in the plant row.
Center Pivot Irrigation —
Place sensors in 4 - 5
locations down the length of the pivot (between
towers) just ahead of the ‘start’ point. Additional
locations at ‘hot spots’ or good production areas of
the field can help give a better overall view of the
field.
Drip or Micro Irrigation — Sensors must be located
in the wetted area. With drip emitters, this is usually
12"- 18" (30- 45cm) from the emitter. With microsprinklers, usually 24"-36" (60-90cm) is best.
Monitor often enough to get a good overall picture
of the field, or irrigation ‘block’, and consider the soil
variations which exist. Keep in mind that light soils
dry very quickly and heavy soils more slowly.
Depth — This depends on the rooting depth of your
crop, but can also be affected by soil depth and texture.
With shallow rooted vegetable crops, one depth may
be adequate (root system less than 12" [30cm]). With
deeper rooted row crops (small grains, vines and trees)
measure soil moisture in at least two depths. With
6
deep, well-drained soils, crops will generally root
deeper – if moisture is available. With coarse, shallow
or layered soils, root systems may be limited in depth.
In general, sensors must be located in the effective
root system of the crop. Guidelines on proper depths
for specific crops and conditions can be obtained from
us as well as from your local farm advisor.
NOTE: Our recommendation for anyone using sensors
for the first time is to use an adequate number of
‘stations’ over a smaller area to begin with to get an
accurate picture. Then read them regularly over the
season to learn the patterns which normally develop.
SENSOR INSTALLATION — WATERMARK Soil
Moisture Sensors must be ‘conditioned’ prior to
installation. The sensors should be soaked to
saturation then dried fully twice, then soaked to
saturation again prior to installation. This ‘conditioning’
of the sensors ensures quick response to changing soil
moisture conditions. If a sensor is only soaked and
then installed, several irrigation cycles must pass
before the sensor will respond accurately. Soak the
sensors in a bucket of water for several hours to
saturate them. Hang them up overnight to dry
sufficiently. After ‘conditioning’ they are ready for
installation. Sensors MUST be installed WET in the
active root zone of plants that are typical of the area the
WATERMARKs monitor. Install either vertically or up to
a 45° angle. Bore a 7/8" (22mm) diameter access hole
to the desired depth, then insert the sensor. Be careful
to ensure a snug fit between the sensor and the
surrounding soil then backfill the hole firmly. The
access hole can be made by pounding a 7/8" (22mm)
diameter bar (or 1/2" [13mm] size IPS pipe) into the soil
or using a coring tool or IRROMETER Installation Tool
to the desired depth, then extracting the selected tool,
being careful not to disturb the soil surrounding the
borehole. With hard or rocky soil, a larger diameter
hole can be made with a soil auger. Mix the auger
cuttings with water to create a slurry and pour into the
borehole. Then insert the sensor into the hole. Once
the slurry dries, the sensor will have been “grouted” in
to ensure good contact with the soil. The sensor can be
attached to 1/2" (13mm) class 315 PVC (thin wall SDR
13.5) or 3/4" (19mm) CPVC (SDR 11) pipe with a
transition solvent PVC to ABS cement. The pipe
becomes a conduit to protect the sensor wires. Also,
this makes the sensor easier to push into the access
hole and remove, if desired. The top of this pipe section
7
should be capped or plugged so surface water does
not travel down to the sensor. Drill a small hole in the
side of the pipe just above the sensor to allow water to
drain away if it becomes trapped in the pipe.
(See
‘IRROMETER Installation Tools’ for other options.)
The
soil temperature sensor should be installed in the soil
near a representative soil moisture sensor. All the soil
moisture sensor readings per Node will be
compensated by the soil temperature sensor. Bore a
1/2" (13mm) diameter hole in the soil and insert the
temperature sensor then backfill the hole. Refer to
instructions that accompany all other sensors for
proper installation. The switch closure sensor is a
pressure gauge with a 1/4" NPT connection and an
adjustable switch mounted to its face. The gauge is
installed into the irrigation pipeline. The pressure range
of the gauge should be selected so that the normal
system pressure is in the middle third of the gauge
range. The normal system pressure is the set point
which will trip the switch, indicating that an irrigation is
taking place.
SENSOR WIRING —
Additional wire can be added to
the sensors for long distances. Please adhere to the
following wire size recommendations when adding wire:
DISTANCE WIRE SIZE
Up to 1000 ft. (300 m) . . . . . . . AWG UF 18 (1.02 mm, 0.82 sq mm)
1001 to 2000 ft. (600 m) . . . . . AWG UF 16 (1.29 mm, 1.31 sq mm)
2001 to 3000 ft. (900 m) . . . . . AWG UF 14 (1.63 mm, 2.08 sq mm)
Multi-conductor wire can be used and twisted pairs are
not necessary. All splices should be made with direct
burial type waterproof splices, Spears DBY
®
or similar.
Be sure to record each pair of sensor wires indicating
what type of sensor is attached and the placement
depth per Node.
NOTE: Videos describing the IRROmesh System and
how to install it are available from the
VIDEOS tab at:
www.IRROMETER.com.
MAINTENANCE — Keep all Node solar panel lenses
clean and clear of any shadows to ensure steady
charging. Monitor the presence of each Node and their
comparative current levels in the WEB display. Units
that ‘drop-out’ or have non-typical voltages likely need
to be inspected for shading or cleanliness.
All Nodes can be ordered from the factory with bird
deterrent covers or retro-fitted with the purchase of a
bird deterrent cap.
TROUBLESHOOTING — Each Node has three lights
that will flash in certain sequences. Check these light
functions to see what may be causing a problem:
SEEKING NETWORK —
RED, YELLOW + GREEN
— Scrolling Rapidly = Unassociated Node
RED + YELLOW
— Blinking = Active, scanning network
NORMAL OPERATING MODE —
If GREEN LED is:
—
Flashing = Node awake
—
Intermittent Blinking / Pulsating =
Power save (system napping)
— Off = Sleeping or no power
If
YELLOW LED is:
—
On = Node non-operational
—
Blinking = indicates Network activity
—
Off = No current Network activity
If
RED Light is:
—
Off = No errors
—
Blinking = error in sending message
through Network
—
On 1 second or more = low power
NOTE: A Logger can appear to be fully associated,
showing a green flashing light but not collecting data if
it has been synced to the computer clock before being
associated to the Base. If such is the case, reset it and
go through the association process again.
Contact IRROMETER Tech Support regarding the
display of any light sequences not mentioned here.
DATA DOESN’T UPLOAD FROM YOUR
COMPUTER
— Some anti-virus software has been
known to block SensMitPath from transmitting data to
the Web. To rectify, add SensMitPath to the list of
approved programs on your anti-virus exceptions page
then click ‘OK’ or ‘Allow’ to permit access.
RESETTING PROCEDURES — On occasion, it may
become necessary to reset your system. Follow the
instructions below to reset any of the components you
are using. None of the data stored in the device will be
lost when resets occur.
To reset the entire system, turn off power to the
Base Node for 24 hours, then re-power the Base and
allow time for each Node to join the system. This may
be necessary if incorrect Node routing associations
were created when deploying Nodes.
Base Node – Cover the solar
panels of the Base Node and slide
the power switch inside the
capacitor housing to ‘OFF’.
PC Link – Temporarily disconnect
the USB cable from the computer.
Cell Gateway Battery Pack –
Open the blue box and
temporarily disconnect the
Gateway’s BLACK and RED
wires from the terminal strip.
Logger –
Temporarily cover the solar
panels of the Logger and slide the power
switch inside the capacitor housing to
‘OFF’.
If the WATERMARK Handheld Digital Meter
(#30KTCD-NL) is being used to manually read a
sensor that is connected to a Node, the sensor wires
MUST be physically disconnected from the Node prior
to connecting the meter to take a manual reading.

Wiring Details
CONNECTING TO WATERMARK SENSORS
Use waterproof wire connectors.
1.Insert one side of a Node wire pair and one side of the corresponding sensor wire pair into
one connector. Repeat for the other wire in the Node pair and the remaining sensor wire with
another connector. One connector per individual Node wire is needed.
Be sure to
INDIVIDUALLY insulate ALL unused wires. DO NOT leave unused Node wires
un-insulated and allowed to corrode, touch each other or touch the metal pole.
2.Repeat for each sensor being installed.
NOTE: Wires are paired by color. One is a solid color and the other is the
same color with a black stripe.

After registration on SensMitWeb, notice that the sensor data in the graph view is color coded to the wire
colors on the Nodes. WATERMARK lines are green, blue and gray (for white), the temperature line is red, the
rain event is indicated by yellow vertical bars and irrigation events are brown vertical bars.
