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.
Make
sure
the
mote
is
mounted
a
minimum
of
1.8
m
(6
ft)
from
the
ground
to
help
maximize
distance
and
signal
strength.
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.
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
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.
Sensor
Mounting
Guidelines
It
is
recommended
that
the
probe
be
protected
from
direct
exposure
to
the
weather.
This
will
prolong
the
sensor
accuracy.
Refer
to
the
station
manual
and
Tripod
Setup
Guide
at
www.onsetcomp.com/support/manuals
for
more
information
regarding
setting
up
stations.
Maintenance
The
temperature/RH
sensor
is
sensitive
to
dust,
salts
and
other
airborne
contamination.
Periodically
inspect
the
RH
sensor.
If
contamination
is
present
on
the
protective
cap,
gently
rinse
it
with
cool
fresh
water.
If
the
sensor
itself
is
contaminated,
you
can
rinse
it
with
distilled
water.
Do
not
use
hot
water,
organic
solvents,
or
detergents.
Dry
before
use.
Periodically
inspect
the
mote
and
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.
Updating
Mote
Firmware
If
a
new
firmware
version
is
available
for
the
mote,
use
HOBOlink
to
download
the
file
to
your
computer.
1.
In
HOBOlink,
go
to
Devices,
then
RX
Devices,
and
click
your
station
name.
2.
On
the
station
page,
click
Overview
and
scroll
down
to
Device
Information.
3.
Click
the
Wireless
tab.
This
icon
appears
next
to
the
mote
if
there
is
a
new
version
of
firmware
available.
4.
Click
the
firmware
upgrade
link.
Click
Download
and
save
the
firmware
.bin
file
to
your
computer.
5.
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.
6.
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.
7.
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
1.5
V
lithium
batteries
(HWSB
‐
LI).
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.
To
install
lithium
batteries:
1.
Open
the
mote
door.
2.
Remove
any
old
batteries
and
install
the
new
ones
observing
polarity.
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.
