RXW Temperature/RH Sensor (RXW-THC-xxx)
Quick Start

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- rx2106manual for RX2105 and RX2106 stations or www.onsetcomp.com/manuals/rx3000-qsg for RX3000 stations).

This signal strength icon Once a network is found, the blinks while searching for icon stops blinking and the a network.
Press the Search button. The magnifying glass icon blinks while the station is in search mode waiting for sensor nodes to join the network.
Open the sensor node door and install the rechargeable batteries. Press this button on the sensor node for 3 seconds.
Watch the sensor node LCD while it joins the network:

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 three (two for temperature/RH and one for the sensor node battery).
Press the Search button on the station again to stop the search for sensor nodes.
Go to www.hobolink.com to monitor sensor node status and health. See the HOBOlink Help for details.

Installing the Bracket and Sensor Node

Orient the bracket so the text TOP is facing upwards.
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.
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.
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.
Use the short screw included in the package to fasten the sensor node to the bracket.
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.

Sensor Mounting Guidelines

When mounting the probe, thermally isolate the sensor from the mounting surface to ensure accurate air temperature and humidity readings.
It is recommended that the probe be protected from direct exposure to the weather. This will prolong the sensor accuracy.
If the sensor cable is left on the ground, use conduit to protect against animals, lawn mowers, exposure to chemicals, etc.
A solar radiation shield is strongly recommended when measuring outdoor air temperatures in direct sunlight. Mount the sensor with the solar radiation shield (RS3-B) as shown.
