User manual (this manual)
Table 1: Package content
If components are missing from the package, or broken, please contact
customer service to resolve the issue.
Note: The console can store historical data on a memory card. This
memory card is not included. If you want to use one you will need
a microSD memory card. There is no required size for this card. A
1GB card will store more than 10 years’ worth of data, so you do
not need a very large capacity card. There is also no requirement on
the speed class of this card as data writing happens infrequently and
is not speed critical.

6
Note: Batteries for the wireless anemometer and the rain gauge sensor are
all not included. You will need 1 AA size battery, alkaline or
Lithium battery (Lithium recommended for colder climates) for each
unit.
Note: The console operates using an AC adapter. The included adapter is a
switching-type adapter and can generate a small amount of electrical
interference with the RF reception in the console, when placed too
close to the console. Please keep the console display at least 2 ft. or
0.5 m away from the power adapter to ensure best RF reception
from the outdoor sensor package.
Note: There are two sets of U-bolts in the box, one is for the wireless
anemometer sensor and the other one is for the rain gauge sensor.
There’s a short stainless steel tube included for the rain gauge sensor
installation.

4Set up Guide
To complete assembly you will need a Philips screwdriver (size PH0) and a
wrench (size M5; included in package).
Note: We suggest you assemble all components of the weather station,
including 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
therefore best if you do not connect the console to any Internet
services until you have reset these false readings using the console.
The errant values may be hard to remove from Internet services if
you do not reset first.
Attention:
•Follow suggested order for battery installation (outdoor sensor first,
console second)
•Ensure batteries are installed with correct polarity(+/-)
•Do not mix old and new batteries
•Do not use rechargeable batteries
•If outdoor temperature may go below 32F or 0C for prolonged periods,
Lithium based batteries are suggested over alkaline type batteries for the
outdoor sensor array
4.1 Site Survey
Perform a site survey before installing the weather station. Consider the
following:
Anemometer
•Ideally mounted at 32.8 feet (10 meters) above groundlevel.
•Try to make the anemometer the highest object around. 7 feet(2.76
meters) or more above the surrounding obstructions isbest.

12
Rain Gauge
•Ideally mounted at a height of 4 to 6 feet above theground.
•Ideally located at a horizontal distance of 4 times the height of the
nearest obstruction.
•Ensure the gauge is mounted level to the ground, away from any
horizontal surface that can introduce rain-splashing or surrounding
snow buildup.

Table 2: Sensor assembly detailed items
4.2.2 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 7, 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 bottom of 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-
degree angle and has a curved profile (which will end up “hugging” the
mounting pole). Once the metal plate is inserted, remove nuts from the U-
Bolts and insert both U-bolts through the respective holes of the metal plate
as shown in Figure 7.
Figure 7: 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 8.

14
Figure 8: U-Bolts and nuts installed
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
of the sensor package with wind vane and speed cups installed to install
these bolts is more difficult and more likely to lead todamage.
4.2.3 Install wind vane
Push the wind vane onto the shaft on the bottom side of the sensor package,
until it goes no further, as shown on the left side in Figure 9. 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.

15
Figure 9: Wind vane installation diagram
4.2.4 Install wind speed cups
Push the wind speed cup assembly onto the shaft on the opposite side of the
wind vane, as shown in Figure 10 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.
Figure 10: Wind speed cup installation diagram

16
4.2.5 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 start over, but if you see the flash once every 16.5 seconds,
everything should be OK.
Figure 11: Battery installation diagram
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.
4.2.6 Mount assembled wireless anemometer sensor
4.2.6.1 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

17
you keep the anemometer sensor nearby (although preferably not closer than
5 ft. or 1.53m from 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.
4.2.6.2 Mounting
You can attach a pole to a permanent structure and then attach the sensor
package to it (see Figure 12).
The U-Bolts will accommodate a pole diameter of 1-2 inches (pole not
included).
Figure 12: Sensor package mounting diagram
Make sure the mounting pole 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

18
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
“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 capacitors. Secondly it causes a zero reading for
wind direction to correspond to due NORTH, as is customary.
Make sure the sensor package is installed vertically. If it is not, wind
direction and speed readings may not operate correctly or accurately. Adjust
the mounting pipe as necessary.
Make sure you check, and correct if necessary, the north orientation 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.
4.2.7 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 (item 10)
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.

4.3.1 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 14. Next, lock the top
clockwise to the lock groove position, as shown on the right side, until the
top cannot be removed from the bucket.

20
Figure 14: Rain collector top installation diagram
4.3.2 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.
Figure 15: Rain gauge sensor battery installation diagram
The LED indicator on the top of the battery door (item 2) will turn on for 4
seconds and then flash once every 49 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 start over, but if you
see the flash once every 49 seconds, everything should beOK.
