5.3.5.2 Mounting
You can attach a pipe to a permanent structure and then attach the sensor
package to it (see Figure 7).
The U-Bolts will accommodate a pipe diameter of 1-2 inches (pipe not
included).
Figure 7: Sensor package mounting diagram
Make sure the mounting pipe is vertical, or very close to it. Use a level if
needed.
Finally, place the sensor package on top of the prepared mounting pipe. The
U-Bolts should be loose enough to allow this but loosen the nuts as
necessary. Once placed, hand tightens all four nuts, taking care to do so
evenly. Do not use a wrench yet!
Now you will need to align the whole package in the proper direction by
rotating it on top of the mounting pipe as needed. Locate the arrow labeled
"WEST" that you will find on top of the sensor package right next to the
light sensor, on the opposite side of the solar panel. You must rotate the
whole sensor package until this arrow points due west. To achieve proper
alignment, it is helpful to use a compass (many cell phones have a compass
application). Once rotated in the correct orientation, lightly tighten the bolts
a little more (use a wrench) to prevent further rotation.
