Adding a Sensor Node to the HOBOnet® Wireless Sensor Network
Important: Keep the sensor node near the station while completing
these steps.
If you are setting up a new station, follow the instructions in the
station quick start guide before setting up this sensor node (go to
www.onsetcomp.com/manuals/24500-rx2105-and-rx2106-manual
for RX2105 and RX2106 stations or
www.onsetcomp.com/manuals/rx3000-qsg for RX3000 stations).

6 Go to www.hobolink.com to monitor
sensor node status and health. See the
HOBOlink Help for details.
Press the Search button. The magnifying glass icon blinks while the
station is in search mode waiting for sensor nodes to join the network.
Press the Select button on the station to switch to the module with
the manager (module 2 on RX2105 or RX2106 stations).
Open the sensor node door and install the rechargeable
batteries. Press this button on the sensor node for 3 seconds.
Press the Search button on the station again to stop the
search for sensor nodes.
This signal strength icon
blinks while searching for
a network.
Once a network is found, the
icon stops blinking and the
bars cycle from left to right.

This network connection
“x” icon blinks while the
sensor node completes
the registration process,
which may take up to
five minutes.
Once the sensor node has
finished joining the network, the
“x” icon is no longer displayed
and the channel count on the
station LCD increases by two
(one for the pulse input sensor
and one for the sensor node
battery).

Installing the Bracket and Sensor Node
1
Orient the bracket so the text TOP is facing
upwards.
2
To install the bracket onto a wall, use
the two long screws included in the
package. Screw the bracket to a wall
using the two holes on the mid-section
of the bracket.
3
To install the bracket
onto a pole, slip a cable
tie through each of the
channels on the bracket
and fasten the tie
around the pole.
4
Insert the bottom of the
sensor node into the retaining
clips on the bottom of the
bracket then press the top of
the sensor node into the clips
at the top of the bracket.
5
Use the short screw
included in the package to
fasten the sensor node to
the bracket.
6 Close the sensor node and use a padlock to keep it secure.
Note: Ensure that the node seal is clean from foreign
debris.

Mounting and Positioning the Sensor Node
•Position the sensor node 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 sensor node 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 sensor node is mounted a minimum of 1.8 m (6 feet) from the ground or vegetation to help maximize distance and
signal strength.
•Consider using plastic poles such as PVC to mount the sensor node as certain types of metal could decrease the signal strength.
•Place the sensor node so there is full line of sight with the next sensor node. Use a repeater if there is an obstruction between sensor
nodes.
•There should not be more than five sensor nodes in any direction from a repeater or the manager. Data from sensor nodes travels or
“hops” across the network and may not reach the station if the sensor node is more than five hops away.
Input Connections
The pulse input sensor has two input connections. The white wire (+) is powered at 3.3 V through a 100 KΩresistor. This power is
supplied from the sensor node battery. The black wire (-) is connected to the sensor node’s ground connection. The input cable can be
connected directly to screw terminals on the sensor or to sensor cables with the included wire nuts.

Connection Using Wire Nuts
Important: If using wire nuts, make sure the connection is protected from the elements.
1. Strip 1 cm (0.39 in.) of insulation from the end of wires, taking care not to nick the metal conductors.
2. Twist the stripped wires together clockwise and then screw on the wire nut clockwise.
3. Check the connection by gently pulling on the wires to verify a solid mechanical connection. Always strain-relief the connection to
make sure that the connection is not broken by being jerked or repeatedly worked back and forth.
Pulse Input Sensor Mounting Guidelines
•Coil and secure excess cable with cable ties.
•If cable is on the ground, use a conduit to protect against such things as animals, lawn mowers, and exposure to chemicals.
•When making a connection to a third-party sensor, take time to make sure that the connection is reliable and protected from rain,
dirt, and direct exposure to the elements. Refer to the manufacturer’s product documentation for additional information on
system configuration.
