Table 1: Package content
If any component is missing from the package, or broken, please contact our
Customer Service department to resolve the issue.
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
5
from the power adapter to ensure best RF reception from the outdoor
sensor package.
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. The supported max capacity of the card is 32G(Format: FAT32). A
1GB card will store more than 10 years’ data. There is also no requirement
on the speed class of this card as data writing happens infrequently and is
not speed critical.
Note: Batteries for the ultrasonic anemometer and the rain gauge sensor are not
included. You will need 2 AA size Lithium battery for the ultrasonic
anemometer, which is primarily for startup and backup purpose. After
setup and during normal operation, the unit is getting its power from solar
cell. One AA size battery, alkaline or Lithium (recommended for colder
climates) is required for the rain gauge. Two AA size alkaline batteries are
required for the indoor sensor.
Note: There are two sets of U-bolts in the box, one is for the ultrasonic
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.
Note: The rain gauge can also be mounted to a surface using two screws, so the
included stainless-steel tube is not always necessary!

weather is mostly snowy or rainy, then you may need to
activate the heater by supplying an 12V/1A power (sold separately)
to the sensor heating element for melting accumulated snow or ice,
which can influence wind measurement accuracy significantly.
There’s a built-in thermostat inside the anemometer sensor
to control the power supply for the heat plate, which will automatica

4 Set up Guide
Before you start, you will need a Philips screwdriver (size PH0, not
provided) and find the wrench (size M6) included in package.
Note: We suggest you assemble all components of the weather station, including
base unit 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 Plus app.
Attention:
• Follow the suggested order for battery installation (outdoor sensor(s)
first, indoor sensor(s) second, optional base unit last).
• Ensure batteries are installed with correct polarity (+/-).
• Only use new batteries for all battery-operated sensors.
• Avoid rechargeable batteries being used.
• 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:
Anemometer
• Ideally mounted at least 32 feet, or 10 meters above ground level.
14
• 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 batteries in sensor package
Open the battery compartment with a screwdriver and insert 2 AA Lithium
batteries in the battery compartment, and press “Reset” button, the LED
indicator on the back of the sensor package (item 4) will turn on for 3
seconds and then flash once every 4.8 seconds indicating sensor data
transmission. If you did not pay attention, you may have missed the initial
indication. You can always press the reset button to start over. Make sure
you see the flash once every 4.8 seconds.
If sensor has been put outside for some time, and solar panel has charged up
the internal accumulator fully or partially, if you install the 2 AA backup
Lithium battery, the system might not start up properly. So you can always
make a system reset by press the “Reset” button.
Figure 7: Battery installation diagram
Note:
Please make sure the battery is inserted correctly for its polarity as
the system needs its initial power from this backup battery to start
up the system before solar panel charges up the accumulator and
16
supply system power afterwards. When in high altitude area, during
wintertime, sunshine time is short, thus system needs to be powered
from this backup battery, we recommend Lithium batteries to be
used for cold weather climates. Please avoid alkaline batteries,
especially when internal heater is to be activated during cold and
wet weather conditions as when heater activated, the trapped heat
inside will warm up internally, and alkaline batteries are extremely
susceptible to leakage when temperature is over certain limits. So
Alkaline batteries are forbidden to be used with this anemometer
when heater function is activated.
4.2.2 Mount ultrasonic anemometer assembly
4.2.2.1 Before you mount
Before installing your outdoor sensor in the permanent location, we
recommend operating the device for one week in a temporary location with
easy access. This will allow you to check out all of the functions, ensure
proper operation and familiarize you with the weather station performance.
4.2.2.2 Mounting
• You can attach a pole(not included) to a permanent structure and then
attach the sensor package to it (see Figure 8-12).
• The U-Bolts will accommodate a pole diameter of 1.25-2 inches (pole
not included).
1. Install the base on a pole (1.25inch~2inch) as Figure 8.

3. Attaching the arm tube to the Ultrasonic Sensor as Figure 10.
Figure 10: Sensor package mounting diagram 5-3
4. Insert the arm tube into the base as Figure 11. Be sure to line up the
small hole in the arm with the holes in the base. Insert the machine
screw through the holes in the base and arm. ( if you don’t need to
power up the heater, you should keep the power cord terminal inside
the mounting arm and this can make the installation looks neat and tidy.
You may take it out when needed.)
Figure 11: Sensor package mounting diagram 5-4
19
Make sure the mounting pole is vertical, or very close to it. Use a level as
needed.
5. During wintertime, to prevent ice formed on the reflection surface, the
optional extension cord be connected to a 12v/1.0A outdoor type power
adapter as Figure 12-1 showed below. The outdoor rated adapter and
extended power cable can be purchased separately:
Figure 12-1
Figure 12-1: Sensor package mounting diagram 5-5
As an option, the package includes a 3M extension cable that users can
connect to a 12V / 1.0A outdoor power adapter by themselves.
Accessory Part only, not included!
20
Figure 12-2
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 connector tube of the sensor
package (item 6). 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: In Southern hemisphere, it is not necessary to change the orientation to
SOUTH as its solar panel is a rounded type and it is orientation free for its
charging capability.
Accessory: 3M extension cord
included
21
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.
4.2.3 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 12)
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 4.8 seconds.

see the flash once every 49 seconds, everything should be OK.
Note: If no LED light up or is lighted permanently, make sure the battery is
inserted the correct way or a proper reset is happened. Do not install the
battery backwards. You can permanently damage the outdoor sensor.
We recommend lithium batteries for cold weather climates, but alkaline
batteries are sufficient for most climates.
4.3.4 Mounting
4.3.4.1 Before you mount
Before proceeding with the outdoor mounting detailed in this section, you
may want to skip to setup instructions in section 4.5 and onwards first, while
you keep the assembled rain gauge sensor nearby (although preferably not
closer than 5 ft. from the gateway). 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.
4.3.4.2 Mounting with U-bolts
The mounting assembly includes two U-Bolts and a bracket that tightens
around a 1-2" diameter pole(not included) using the four U-Bolt and nuts.
Note: Use the bubble level on the side of the rain gauge as a guide to verify that
the sensor is leveled (for proper measurements).
25
Figure 17: Rain gauge installation with U-bolts
4.3.4.3 Mounting with screws
The mounting assembly also includes two screws for installation on a flat
surface.
Figure 18: Rain gauge sensor mounting with screws installation diagram
26
Note: Use the bubble level beside the
rain sensor as a guide to verify that the
sensor is leveled. Use shims as necessary to achieve level installation.
4.4 Indoor Sensor Set Up
Note:
To avoid permanent damage, please take note of the battery polarity before
inserting the batteries. Looking at Figure 4
from left to right the left
(or bottom) battery is to be installed with its + terminal pointing down, and
the other battery with its + terminal pointing up.
Remove the battery door on the back of the sensor by sliding it in the
direction of the arrow. Insert two AA batteries as described and put
compartment door back and slide it in the opposite direction to lock.

Figure 4: Indoor sensor battery installation
4.4.1 Sensor Placement
The best mounting location for the indoor sensor is in a location that never
receives direct sunlight, not even through windows.
Also, do not install in a
location where a nearby radiant heat source (radiator, heaters, etc.) will
affect it. Direct sunlight and radiant heat sources will result in inaccurate
temperature readings.
The sensor is meant to provide indoor conditions for di
splay on the console,
but if you would rather have a second source for outdoor conditions instead,
you can mount this unit outside. The unit is weatherproof, but beside

27
heeding the placement instructions above, you should also attempt to mount
the unit under cover (eve or awning or similar).
To mount or hang the unit on a wall or wood beam:
• Use a screw or nail to affix the remote sensor to the wall, as shown on
the left side of Figure , or
• Hang the remote sensor using a string, as shown in right side of Figure
Figure 20: Indoor sensor mounting
Note: Make sure the sensor is mounted vertically and not lying down on a flat
surface. This will insure optimum reception. Wireless signals are impacted
by distance, interference (other weather stations, wireless phones, wireless
routers, TVs and computer monitors), and transmission barriers, such as
walls. In general, wireless signals will not penetrate solid metal and earth
(down a hill, for example).
4.5 Best Practices for Wireless Communication
Wireless (RF) communication is susceptible to interference, distance, walls
and metal barriers. We recommend the following best practices for trouble
free wireless communication between both sensor packages and the base
unit:
• Indoor/outdoor sensor placement: The sensor will have the longest
reach for its signal when mounted or hung vertically. Avoid laying it
down on a flat surface.
28
• Electro-Magnetic Interference (EMI). Keep the base unit several feet
away from computer monitors and TVs.
• Radio Frequency Interference (RFI). If you have other devices
operating on the same frequency band as your indoor and/or outdoor
sensors and experience intermittent communication between sensor
package and base unit, try turning off these other devices for
troubleshooting purposes. You may need to relocate the transmitters or
receivers to avoid the interference and establish reliable communication.
The frequencies used by the sensors are one of (depending on your

• Line of Sight Rating. This device is rated at 300 feet line of sight
(under ideal circumstances; no interference, barriers or walls), but in
most real-world scenarios, including a wall or two, you will be able to
go about 100 feet.
• Metal Barriers. Radio frequency will not pass through metal barriers
such as aluminum siding or metal wall framing. If you have such metal
barriers and experience communication problems, you must change the
placement of sensor package and or base unit.
The following table shows different transmission media and expected signal
strength reductions. Each “wall” or obstruction decreases the transmission
range by the factor shown below.
Medium RF Signal Strength Reduction
Glass (untreated) 5-15%
Plastics 10-15%
Wood 10-40%
Brick 10-40%
Concrete 40-80%

You may jump to section 4.9.16 now to have your console connected with

hosting setup completed.
Your console is capable of sending your sensor data to select internet-based
weather services. The supported services are shown in the table below:
Service Description
Weather Underground Site: https://wunderground.com
provides local & long-range weather forecasts, weather
reports, maps & tropical weather conditions for locations
worldwide.
WOW Site: https://wow.metoffice.gov.uk
A UK based weather observation website.
Weather Cloud Site: https://weathercloud.net
A large network of weather stations reporting data in real

Ecowitt Weather Site: https://www.ecowitt.net
Ecowitt’s new weather server that can host a bunch of
sensors that other services don’t support at this time.
Table: Supported weather services
Note: If you are testing the setup with the outdoor sensor package nearby
and indoor, you may want to consider connecting to Wi-Fi, but not yet
configuring any of the weather services. The reason is that while indoor the
temperatures and humidity recorded by the outdoor sensor, and as reported
to the weather service(s) will reflect indoor conditions, and not outdoor
conditions. Therefore, they will be incorrect. Furthermore, the rainfall
bucket may be tripped during handling, causing rain to register while it may
not actually have been raining. One way to prevent this is to follow all
instructions, except to use an incorrect password, on purpose! Then, after

(1) Temperature errors can occur when a sensor is placed too close to a
heat source (such as a building structure, the ground or trees).
To calibrate temperature, we recommend a mercury or red spirit
(fluid) thermometer. Bi-metal (dial) and digital thermometers (from
other weather stations) are not a good source and have their own
margin of error. Using a local weather station in your area is also a
poor source due to changes in location, timing (airport weather
stations are only updated once per hour) and possible calibration
errors (many official weather stations are not properly installed and
calibrated).
Place the sensor in a shaded, controlled environment next to the
fluid thermometer, and allow the sensor to stabilize for 3 hours.
Compare this temperature to the fluid thermometer and adjust the
console to match the fluid thermometer.
(2) Humidity is a difficult parameter to measure electronically and drifts
over time due to contamination. In addition, location has an adverse
affect on humidity readings (installation over dirt vs. lawn for
79
example).
Official stations recalibrate or replace humidity sensors on a yearly
basis. Due to manufacturing tolerances, the humidity is accurate to
± 5%. To improve this accuracy, the indoor and outdoor humidity
can be calibrated using an accurate source, such as a sling
psychrometer.
(3) The display console displays two different pressures: absolute
(measured) and relative (corrected to sea-level).
To compare pressure conditions from one location to another,
meteorologists correct pressure to sea-level conditions. Because the
air pressure decreases as you rise in altitude, the sea-level corrected
pressure (the pressure your location would be at if located at sea-
level) is generally higher than your measured pressure.
Thus, your absolute pressure may read 28.62 inHg (969 mb) at an
altitude of 1000 feet (305 m), but the relative pressure is 30.00 inHg
(1016 mb).
The standard sea-level pressure is 29.92 in Hg (1013 mb). This is
the average sea-level pressure around the world. Relative pressure
measurements greater than 29.92 inHg (1013 mb) are considered
high pressure and relative pressure measurements less than 29.92
inHg are considered low pressure.
To determine the relative pressure for your location, locate an
official reporting station near you (the internet is the best source for
real time barometer conditions, such as Weather.com or
Wunderground.com), and set your weather station to match the
official reporting station.
(4) Only use this if you improperly installed the weather station sensor
array, and did not point the direction reference to true north.
80
(5) The default conversion factor based on the wavelength for bright
sunlight is 126.7 lux / w/m
2
. This variable can be adjusted by
photovoltaic experts based on the light wavelength of interest, but
for most weather station owners, is accurate for typical applications,
such as calculating evapotransporation and solar panel efficiency.
(6) Wind speed is the most sensitive to installation constraints. The rule
of thumb for properly installing a wind speed sensor is 4 x the
distance of the tallest obstruction. For example, if your house is 20’
tall and you mount the sensor on a 5’ pole:
Distance = 4 x (20 – 5)’ = 60’ or =4 x (6.10-1.52)=18.32m.
Many installations are not perfect and installing the weather station
on a roof can be difficult. Thus, you can calibrate for this error with
a wind speed multiplier.
In addition to the installation challenges, wind cup bearings (moving
parts) wear over time.
Without a calibrated source, wind speed can be difficult to measure.
We recommend using a calibrated wind meter (not included) and a
constant speed, high speed fan.
(7) The rain collector is calibrated at the factory based on the funnel
diameter. The bucket tips every 0.01” or 0.1m of rain (referred to as
resolution). The accumulated rainfall can be compared to a sight
glass rain gauge with an aperture of at least 4” or 0.1m.
Make sure you periodically clean the rain gauge funnel.
Note: The purpose of calibration is to fine tune or correct for any sensor
error associated with the devices margin of error. Errors can occur due to
electronic variation (example, the temperature sensor is a resistive thermal
device or RTD, the humidity sensor is a capacitance device), mechanical
variation, or degradation (wearing of moving parts, contamination of
sensors).
81
Calibration is
only useful if you have a known calibrated source you can
compare it against, and is optional. This section discusses practices,
procedures and sources for sensor calibration to reduce manufacturing and
degradation errors. Do not compare your readings obta
ined from sources
such as the internet, radio, television or newspapers. The purpose of your
weather station is to measure conditions of your surroundings, which vary
significantly from location to location.
Note: UV Calibration MUST
be performed every 2 to 3 months to improve
results. Over time, UV Index may alter results based on bright and strong
sunlight conditions. This is why diligent UV Calibration is recommended.

The reason the current conditions do not match the forecast icon is because
the forecast is a prediction 24-
48 hours in advance. In most locations, this
prediction is only 70% accurate and it is a good
idea to consult the National
Weather Service for more accurate weather forecasts. In some locations, this
prediction may be less or more accurate. However, it is still an interesting
educational tool for learning why the weather changes.
The National Weat
her Service (and other weather services such as
Accuweather and The Weather Channel) have many tools at their disposal to
predict weather conditions, including weather radar, weather models, and
detailed mapping of ground conditions.

6 Maintenance
The following steps should be taken for proper maintenance of your station
Clean Rain Gauge
Check the rain gauge every 3 months. Rotate the funnel counterclockwise
and lift it up. Clean the funnel and bucket with a damp cloth to remove any
dirt, debris and insects. Spray the array lightly with insecticide, if there’s a
bug infestation.
Figure 5: Rain gauge maintenance
91
Clean solar radiation sensor and solar panel
The solar radiation sensor and solar panel of the outdoor sensor array need
to be cleaned with a non-abrasive slightly damp cloth every 3 months.
Replacing batteries regularly
Batteries of the outdoor sensor array should be replaced every 1-2 years. In
applications where data dropouts cannot be tolerated, check the batteries
every 3 months and apply a corrosion preventing compound (not included)
on the battery terminals for protection.
Prevent snow build up
In snowy environments, use anti-icing silicon spray on the top of the
weather station, and rain collection top, to prevent snow build up.
Rain Gauge Accuracy Cross Check
To tell if the rain gauge is accurate or not, it is not correct to compare to a
rain meter nearby around. Because it is not necessary having a same rain
intensity, even I they are not far from each other. To judge if your rain meter
is correct or not, you may do the following:
1. Use a narrowed neck bottle that can sit under the rain gauge water
outlet holes. Collect the water during a rain event and measure its
weight. E.g. 353 g.
2. 353 g equals 353 ml, divided by rain collector size of 250 cm2, you get
353/250 = 1.412 cm = 14.1 mm.
3. Compare the rain readings from your gateway to your local rain event
reading, or a reading from a calibrated manual gauge, to see if they are
matching or not.
4. Since there may be some water left in the tip bucket, and also some on
the rain collector itself, the observed rain is normally slightly less than
the actual rainfall, but his is normally within 5%. If the deviation is
larger than this, then you can change rain calibration settings
accordingly, or contact the customer service for replacement.

7 Troubleshooting Guide
Look through the following table and locate an issue or problem you are
experiencing in the left column and read possible solutions in the right
column.
Problem Solution
Wireless remote (thermo-
hygrometer) not reporting
in to console.
There are dashes on the
display console.
The maximum line of sight communication range
is about 600’. Move the sensor assembly closer to
the display console.
Resynchronize the remote sensor(s).
Install a fresh set of batteries in the remote
sensor(s).
Make sure the remote sensors are not transmitting
through solid metal (acts as an RF shield), or earth
barrier (down a hill).
Radio Frequency (RF) Sensors cannot transmit
through metal barriers (example, aluminum siding)
or multiple, thick walls.
Move the display console around electrical noise
generating devices, such as computers, TVs and
other wireless transmitters or receivers.
Outdoor sensor does not
communicate to the
display console.
The sensor may have initiated properly and the
data is registered by the console as invalid, and the
console must be reset. Press the reset button as
described in Section Installation.
With an open ended paperclip, press the reset
button for 3 seconds to completely discharge the
voltage.
Take out the batteries and wait one minute, while
covering the solar panel to drain the voltage.
Put batteries back in and resync with console by
powering down and up the console with the sensor
array about 10 feet away.
93
Problem Solution
Bring the sensor array inside the house (you can
disconnect it from the rest of the sensors). The
LED next to the battery compartment will flash
according to the reporting time on the
specifications. If the LED is not flashing as
that…
Replace the batteries in the sensor.
If the batteries were recently replaced, check the
polarity. If the sensor is flashing normally, proceed
to the next step.
There may be a temporary loss of communication
due to reception loss related to interference or
other location factors,
or the batteries may have been changed in the
sensor and the console has not been reset. The
solution may be as simple as powering down and
up the console.
Replace the batteries in the sensor.
With the sensor and console 10 feet away from
each other, remove AC power from the display
console and
wait 10 seconds. Re
-
connect power.
Temperature sensor reads
too high in the day time.
Make certain that the sensor is not too close to heat
generating sources or strictures, such as buildings,
pavement, walls or air conditioning units.
Use the calibration feature to offset installation
issues related to radiant heat sources.
Absolute pressure does
not agree with official
reporting station
You may be viewing the relative pressure, not the
absolute pressure.
Select the absolute pressure. Make sure you
properly calibrate the sensor to an official local
weather station. Reference Section 4.9.19 for
details.

Note: The primary power source for the outdoor sensor is the solar panel.
When available solar power (light over recent period) is insufficient, the
batteries will be used. In outdoor climates that frequently have sustained
temperatures below 0°C (or 32°F) the use of Lithium batteries is strongly
suggested as these are performing better than Alkaline batteries under such
circumstances.
