User manual (this manual)
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!

more info needed, please visit our website: http://www.ecowitt.com. Make
sure to select the model of the units with the same RF frequency as your

10
gateway (the frequency is different for various countries because of
regulations).
Note: There’s a built-in heat plate in the 6-in-1 sensor package body, if the lowest
temperature at your place is below -3°C, or 26.6°F, and the weather is
mostly snowy or rainy, then you may need to activate the heater by
supplying an external 5V/1A power to the sensor heating element for
melting accumulated snow or ice, which can influence wind measurement
accuracy significantly. Please contact us at [e-mail] for the
extension cord information if needed.

4 Set 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 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 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.
When outdoor temperature is above 10.0C ( 50.0F), it is forbidden to
feed power to the heating thermostat which can lead to permanent
damage due to excessive heat built up inside and cause unpredictable
damage to the system itself or data accuracy.
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:

12
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 batteries in sensor package
Open the battery compartment with a screwdriver and insert 2 AA 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
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

14
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 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.

15
Figure 8: Sensor package mounting diagram 5-1
2. Pass the connector cord through the arm tube as Figure 9:
Figure 9: Sensor package mounting diagram 5-2
3. Attaching the arm tube to the Ultrasonic Sensor as Figure 10.

16
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
Make sure the mounting pole is vertical, or very close to it. Use a level as
needed.

17
5. If optional extension cord is added, connect the cord to the connector
and insert the USB port into the AC adaptor as Figure 10 show:
Figure 12: Sensor package mounting diagram 5-5
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.

18
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.

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 simple: press the filter until the hook is inside the outlet hole
and self -locked. The spring tension will keep the filter sit tight on the funnel.
Figure 14: 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
Hook the filter hook on the edge to install.
Take out the filter hook from the edge to uninstall.

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!
Figure 15: Rain collector top installation diagram
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. Make
sure battery door is firmly press and closed properly, which is
extremely important in preventing any water entering inside.
Figure 16: 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
