Location Tips Page 3

OCATION

IPS

✦

The Solar Radiation Shield works best when in a location with a steady breeze.
Mount away from fences, buildings, trees, or other obstructions.

✦

Install over plants or soil if possible.

✦

Do not install over or near sprinklers. The Solar Radiation Shield is not designed
to protect the sensor from water sprayed upwards.

✦

If attaching to a building, the preferred location would be on the north side in the
Northern Hemisphere and on the south side in the Southern Hemisphere.

PTIONS

The Solar Radiation Shield may be mounted in three basic orientations: on the
side of a wooden post or a wall, on a metal pipe with outside diameter between
1” and 1 1/4” (25 mm and 31 mm), or on top of a wood post. Each of these con­figurations is pictured below. You should determine ahead of time which orien­tation best suits your purpose because the installation instructions differ
slightly depending on how you plan to finally mount the Solar Radiation
Shield.

The Solar Radiation Shield can house the HOBO Pro Series data loggers and
temperature sensors from the HOBO H8 Outdoor/Industrial 4-Channel Exter­nal data logger. This includes the HOBO Pro H08-030-08 Temp, H08-031-08
T emp/External Temp, H08-032-08 RH/T emp and external temperatur e sensors
from the H08-008-04 HOBO H8 Outdoor/Industrial 4-Channel data logger.

Attaching the HOBO Pro Data Logger (all part numbers H08-030-08,
H08-031-08 and H08-032-08) to the Solar Radiation Shield

In order to attach the HOBO Pro data logger to the Solar Radiation Shield you
will need a closed plate, two #4 x 1/2” pan head self-threading screws, and the
HOBO Pro data logger. If you are installing a HOBO Pro P/N H08-031-08
Temp/External Temp logger you will also require a cable clamp, one #4 x 1/2”
pan head self-threading screw and a #4 flat washer.

1. Position the HOBO Pro data logger on the closed plate, lining up any two opposing
holes in the mounting posts, with the holes on the data logger mounting ears.

Make sure you orient the data logger with the metal base side against the
closed plate, and the label side away from the closed plate.

2. Using two #4x1/2” pan head self-threading screws, attach the data logger to the
closed plate.

Tighten to a snug fit only. Do not over tighten or you may crack the data log­ger mounting ears.

Note: If you have a HOBO Pro P/N H08-031-08, Temp/External Temp logger proceed with Step #3. If you

have HOBO Pro P/N H08-030-08, Temp or H08-032-08, RH/Temp loggers skip Step #3 and #4.

3. Place the cable clamp around the external temperature sensor cable on the HOBO Pro

Temp/External Temp data logger approximately 4” (10 cm) from the data logger.

4. Attach the cable clamp to one of the remaining posts on the closed plate (using a

#4 x 1/2” pan head self-threading screw and a #4 flat washer) so that a loop
of cable is formed between the data logger and the cable clamp.

Make sure to mount the cable clamp with the flat side up and the bulge side
down. Tighten the screw snugly so that the cable cannot move easily
through the cable clamp if pulled on. When testing for a tight hold, do not
pull hard on the cable or you may damage it.

Attaching an External Temperature Sensor from the HOBO H8
Outdoor/Industrial 4-Channel External Logger to the Solar Radiation Shield

In order to attach an External Temperature Sensor to the Solar Radiation
Shield, you will need a closed plate, both clip mounts, the cable clamp, three
#4 x 1/2” pan head self-threading screws, three #4 flat washers, and the tem­perature sensor.

1. Place the sensor cable into the notch on one of the clip mounts and hold it in place.

Make sure to hold the clip mount so the raised semi-circle at the top of the
notch faces up.

2. Position the second clip mount over the first, with the notch facing in the opposite

direction, securing the sensor cable between the two notches.

When positioning the second clip mount, make sure the raised semi-circle
faces down.
