4Set up Guide
Before you start, you will need a Philips screwdriver (size PH0, not
provided) and find the wrench (size M5) included in package.
Note: We suggest you assemble allcomponents of the weather station, including
(optional) console in one location so you can easily test functionality. After
testing, place the outdoor sensors in the desired location. Note, however,
that movement during assembly, and movement after assembly can cause
the rain sensor to “falsely” register rain. It is possible to reset the rain total
to 0 via WS View app.
Attention:
Follow the suggested order for battery installation (outdoor sensor(s)
first, indoor sensor(s) second, optional console last).
Ensure batteries are installed with correct polarity (+/-).
Only use new batteries for all battery-operated sensors.
Never use rechargeable batteries of any kind, except for the anemometer
and rain gauge, where you can optionally use low-self-discharge type
rechargeable batteries.
If outdoor temperature may go below 32 F or 0 C for prolonged periods,
Lithium based batteries are suggested over alkaline type batteries for
any outdoor sensor.
4.1 Site Survey
Location of various sensors is paramount to good data collection.
Abbreviated instructions follow, but for a detailed reference, see:
https://www.weather.gov/media/epz/mesonet/CWOP-Siting.pdf.
Perform a site survey before installing the weather station. Consider the
following:

11
Anemometer
Ideally mounted at least 32 feet, or 10 meters above ground level.
Try to make the anemometer the highest object around. 7 feet, or 2.75
meters) or more above the surrounding obstructions is best.
Rain Gauge
Ideally mounted at a height of 4 to 6 feet, or 1.5 to 2 meters above the
ground.
Ideally located at a horizontal distance of 4 times the height, above the
rain gauge, of the nearest obstruction.
Ensure the rain gauge is mounted level to the ground, away from any
horizontal surface that can introduce rain-splashing or surrounding snow
buildup.

Table 2: Sensor package assembly component list
4.2.1 Install U-bolts and metal plate
Installation of the U-bolts, which are in turn used to mount the sensor
package on a pole, requires installation of an included metal plate to receive
the U-bolt ends. The metal plate, visible in Figure 6, has four holes through
which the ends of the two U-Bolts will fit. The plate itself is inserted in a
groove on the right bottomof the unit. Note that one side of the plate has a
straight edge (which goes into the groove), the other side is bent at a 90-

13
degree angle and has a curved profile (which will end up “hugging” the
mounting pole). Once the metal plate is inserted, remove nuts fromthe U-
Bolts and insert both U-bolts through the respective holes of the metal plate
as shown in Figure 6.
Figure 6: U-Bolt installation
Loosely screw on the nuts on the ends of the U-bolts. You will tighten these
later during final mounting. Final assembly is shown in Figure 7.
Figure 7: U-Bolts and nuts installation
The plate and U-Bolts are not yet needed at this stage but doing this now
may help avoid damaging wind vane and wind speed cups later on. Handling

14
of the sensor package with wind vane and speed cups already installed to
then install these bolts is more difficult and more likely to lead to damage.
4.2.2 Install wind vane
Push the wind vane onto the shaft on the bottomside of the sensor package,
until it goes no further, as shown on the left side in Figure 8. Next, tighten
the set screw, with a Philips screwdriver (size PH0), as shown on the right
side, until the wind vane cannot be removed from the axle. Make sure the
wind vane can rotate freely. The wind vane’s movement has a small amount
of friction, which is helpful in providing steady wind direction
measurements.
Figure 8: Wind vane installation diagram
4.2.3 Install anemometer cups
Push the wind speed cup assembly onto the shaft on the opposite side of the
wind vane, as shown in Figure 9 on the top side. Tighten the set screw, with
a Philips screwdriver (size PH0), as shown on the right side. Make sure the
cup assembly can rotate freely. There should be no noticeable friction when
it is turning.

15
Figure 9: Wind speed cup installation diagram
4.2.4 Install batteries in sensor package
Open the battery compartment with a screwdriver and insert 1 AA battery in
the battery compartment. The LED indicator on the back of the sensor
package (item 6) will turn on for 3 seconds and then flash once every 16.5
seconds indicating sensor data transmission. If you did not pay attention,
you may have missed the initial indication. You can always remove the
batteries and press the reset button to start over. Make sure you see the flash
once every 16.5 seconds.
Figure 10: Battery installation diagram

16
Note: If LED does not light up or is on permanently, make sure the battery is
inserted the correct way and inserted fully, starting over if necessary. Do
not install the battery backwards as it may permanently damage the outdoor
sensor.
Note: We recommend Lithium batteries for cold weather climates, but alkaline
batteries are sufficient for most climates. Rechargeable batteries have
lower voltages and should never be used.
4.2.5 Mount wireless anemometer assembly
4.2.5.1 Before you mount
Before proceeding with the outdoor mounting detailed in this section, you
may want to skip to setup instructions in section 5-7 and onwards first, while
you keep the anemometer sensor nearby (although preferably not closer than
5 ft. or 1.5 mfrom the display console). This will make any troubleshooting
and adjustments easier and avoids any distance or interference related issues
from the setup.
After setup is complete and everything is working, return here for outdoor
mounting. If issues show up after outdoor mounting they are almost
certainly related to distance, obstacles etc.
4.2.5.2 Mounting
You can attach a pole to a permanent structure and then attach the
sensor package to it (see Figure 11).
The U-Bolts will accommodate a pole diameter of 1-2 inches (pole not
included).

17
Figure 11: Sensor package mounting diagram
Make sure the mounting pole is vertical, or very close to it. Use a level as
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 tighten 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
“NORTH” that you will find on top of the transparent cover on the sensor
package (item 8). You must rotate the whole sensor package until this arrow
points due north. 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.
Note: The orientation to NORTH is necessary for two reasons. The most
important one is to position the solar panel and light sensor in the most
advantageous position for recording solar radiation and charging internal

18
capacitors. Secondly it causes a zero reading for wind direction to
correspond to due NORTH, as is customary.
Note: When installing in a location on the southern hemisphere, the north
indicator should actually be made to point due south so that the solar panel
will receive optimal sunlight. Without correction this will cause wind
directions to be opposite from what is expected. Use the mobile
applications calibration functions to give the wind direction a 180-degree
offset to compensate for this.
Make sure the mounting tube for the sensor package is installed vertically
(use a level at 90-degree offsets around the tube). Adjust the mounting pipe
as necessary. Next also make sure the mounting of the anemometer body on
the pipe is level. If it is not, wind direction and speed readings may not
operate correctly or accurately. Adjust the mounting assembly as necessary.
Make sure you check, and correct if necessary, the north orientation again,
as the final installation step, and now tighten the bolts with a wrench. Do not
over tighten, but make sure strong wind and/or rain cannot move the sensor
package.
4.2.6 Reset Button and Transmitter LED
In the event the sensor package is not transmitting, reset the sensor.
Using a bent-open paperclip, press and hold the RESET BUTTON (item10)
to affect a reset: the LED turns on while the RESET button is depressed, and
you can now let go. The LED should then resume as normal, flashing
approximately once every 16.5 seconds.
4.3 Rain Gauge Sensor Set Up and Installation

4.3.1 Install rain gauge filter
There’s a stainless steel filter included in the package. It’s aimed to stop
leaves or bird's dropping to avoid the obstruction of the cone hole. The
installation is as simple as the below figures show:
Hook the filter hook on the edge of the rain collector to install the filter(as
the figure below shows on the left).
Take out the filter hook fromthe edge to uninstall the filter(as the figure 2
shows on the right).

Figure : Rain gauge filter in/un-installation diagram
4.3.2 Install rain collector top
Align the rain collector top with the rain bucket, pay attention to the lock
groove position as shown on the left side in Figure 13. Next, lock the top
clockwise to the lock groove position, as shown on the right side of the
figure, until it comes to a stop and the top cannot be removed from the
bucket. Failure to do this may cause the collector top to blow away in strong
winds!

4.3.3 Install Batteries in rain gauge sensor
Remove the battery door on the back of the sensor by sliding it in the
direction of the arrow. Insert one AA battery as described and put
compartment door back and slide it in the opposite direction to lock.
