AbouttheHOBOnodeOutdoorWirelessSystem
Overview
HOBOnodewirelesssensorsmonitortemperatureandsoilmoistureconditionsandtransmitthedatabacktoyour
computer.Theyenableyoutoviewcurrentconditionsthrougharemotesensor,receivealarmnotifications,andlogdata
onyourPCwithouthavingtoruncablesthroughthefield.
TheHOBOnodeOutdoorWirelessSensorsareeasytodeployandmove.Therearenocablestorunthroughcropsorwalls,
youarenotlimitedbyphysicalcablelengthlimits,andthereislesschanceforlosingmeasurementsfromcabledamage.

HOBOnodeOutdoorWirelessTemperatureSensor
TheHOBOnodeOutdoorWirelessTemperatureSensorcanbeusedinair,soil,orwater.Thesensorisdesignedtolastat
leastoneyearinwateraswarmas+50°C(+122°F).Ifthesensoriscontinuallyexposedtowaterformorethanayear,itwill
eventuallydrift.Exposuretowaterabove+50°C(+122°F)isnotrecommendedandmaysignificantlyreducethelifeofthe
sensor.
HOBOnodeOutdoorWirelessSoilMoistureSensor
TheHOBOnodeOutdoorWirelessSoilMoistureSensormeasuresthedielectricconstantofsoilinordertodetermineits
volumetricwatercontent.Thedielectricconstantofwaterismuchhigherthanthatofairorsoilminerals,whichmakesita
sensitivemeasureofthewatercontent.Duringoperation,valuesof0to0.5m3/m3arephysicallypossible.
BatteryOptions
TheHOBOnodesandHOBOnodeRepeatersareshippedwithrechargeablealkalinebatteriesthatgetrechargedbythe
internalsolarpanel.UseOnset‐suppliedlithiumbatteriesforincreasedoperatingtemperaturerangedownto‐40°C(‐40°F)
andwhenusinginapplicationswithelevatedtemperatures.Lithiumbatteriesarenotrechargeable.

Topologies
ThefollowingillustrationshowsasampledeploymentofaHOBOnodeOutdoorWirelessSystem.

8HOBOnodeOutdoorWirelessSystemUser’sGuide
TheoryofOperation
Standard
TheHOBOnodeOutdoorWirelessSystemusestheIEEE802.15.4wirelessdatastandardinthe2.4Ghzspectrum.Thisisan
ISMbandtechnology,whichislicense‐freeworldwide.Thisradiotechnologywaschosentomaximizebatterylifeand
minimizecost.
CommunicationsProtocol
TheHOBOnodeOutdoorWirelessSystemusesatimeslotbasedcommunicationsprotocol.Eachnodeisassignedaslot
whenitisfoundbytheHOBOnodeReceiver.AllHOBOnodeSensorstaketheirmeasurementsatthesametimeatthestart
oftheoneminutecycleandthentransmittheirdataduringtheirassignedtimeslot.
NetworkID
BecauseitispossibletohavemorethanonHOBOnodeNetworkrunninginthesamearea,itisimportantthatunique
networkIDsareassignedsothatthenetworkscanco‐existpeacefully.AuniquenetworkIDconsistsoftwoelements:anRF
channel,andaUniqueID(anynumberfrom0to4095).
IftwoHOBOnodeNetworksarebeingconfigured,itisbesttoselectdifferentchannelsforthemtouse.Althoughtheycan
shareachannel,thereisapotentialforinterference.NewHOBOnodesandHOBOnodeRepeaterscomefromthefactory
withablanknetworkID.OnceadeviceislinkedtoaHOBOnodeReceiver,itwillonlyrespondtothatHOBOnodeReceiver.
ThenetworkIDcanbeclearedfromadeviceifyouneedtochangeit.
Packets
Inthesimplestexchange,aHOBOnodeisconnecteddirectlytoaHOBOnodeReceiver.Inthiscase,theHOBOnodewillsend
apackettotheReceiver.TheHOBOnodeReceiverreceivesandverifiesthepacket’svalidity(uniquenetworkID,CRCet.),
sendsaReplypackettothedevice,andforwardsthepackettoHOBOnodeViewer(hostsoftware).Forreliabilitypurposes,
packet/replyexchangesareretriedbetweennodesfourtimes.
LostNode
Adevicebecomeslostwhenithasnothadasuccessfulpacket/replyexchange4timesinarow.Bydefault,theHOBOnode
Receiverwillautomaticallysearchforlostnodesonceperhour.
SendingCommands
Commandssenttodevicesmustbecarriedinthereplypacketgeneratedinthepacket/replyexchange.Thismeansa
commandcanonlymoveonehopthroughaHOBOnodeRepeaterinthenetworkeachminute.So,acommandtoadevice
thatisfourhopsdowninthenetworkmaytakeuptofourminutestoreachthedevice.ThemaincommandsareStart
ManualSearch,StopManualSearchandAutoSearch.
Standards
TheHOBOnodeOutdoorWirelessSystemusestheIEEE802.15.4wirelessdatastandard,inthe2.4GHzISMband,whichis
license‐freeforworldwideuse.
