Step 2: Mount the HOBO U30 Station to a pole or wall.
Mount the
HOBO U30 Station vertically to a mast or pole using the U-bolts and a
wrench or socket driver, or mount it vertically to a wall or board using
screws. Make sure the HOBO U30 Station remains in a vertical position
once it is placed in its deployment location.
If it is mounted horizontally,
the antenna will not have optimal range and the battery could be
damaged over time as it is charged.
If you are using U-bolts for mounting,
make sure
the mounting plates are mounted against the flat part of the U-bolt
saddle clamps.

Step 3: Install and mount all sensors on a tripod and/or in their desired
measurement locations.
Follow the instructions in the sensor manuals for
installation and mounting.
Important: All sensors should be mounted at least one foot from the HOBO
U30 Station case because the built-in GSM radio module and
antenna can cause interference with the measurements made by
the sensors. Any excess sensor cables should not be coiled up
and stored inside or within one foot outside the case. The Leaf
Wetness Smart Sensor (S-LWA) is especially sensitive and
should be mounted at least two feet away from the case.

Step 4: Knock out secondary access opening and install the optional
Smart Sensor Expander board
. If you are using the optional Smart Sensor
expander board, you will need to knock out the piece covering the second
opening, install the board if not is not already factory-installed, and then
connect the two boards with the expander cable.
Knock out the secondary cable access opening:
1.
Make sure the HOBO U30 Station is turned off and all cables are
disconnected.
2.
Use a hammer and a bladed tool (e.g., screwdriver, chisel) to punch
through at the four corners and at the ends of the secondary cable
access opening knockout.
