1. Warnings and Cautions
Note:
1. The last firmware in QR code on the box
2. Advance setting on Embeded Web page 192.168.4.1
(You need a computer or phone linking WLAN gateway)
1.1 Optional other accessories (sold
separately)
Accessories: 12V/1A power extension cord; Bird spikes
Note: Batteries for the sensor package are not
included. You will need 2 AA size battery for
the ultrasonic anemometer, which is primarily
for startup and backup power purpose. After
setup and during normal operation, the unit is
getting its power from solar cell.
Note: There’s a built-in heat plate in the 7-in-1
sensor package body, if the lowesttemperature
at your place is below -3°C, or 26.6°F, and the
weather ismostly snowy or rainy, then you
may need to activate the heater bysupplying
an external 12V/1A power to the sensor
heating element formelting accumulated snow
or ice, which can influence wind

theextension cord information if needed.
1.2 Features
•Piezoelectric rain gauge;
•Ultrasonic anemometer (start wind speed 0.3m/s);
•Temperature;
•Humidity;
•Solar light intensity and UV index;
•Waterproof IPX5;
•Heater and additional power supply;
Note: There’s a built-in thermostat inside the
anemometer sensorto control the power supply for the
heat plate, which will automatically turnon below 0℃
(30℉ ) and automatically turn off above 10℃ (50℉ ).

3. Setup Guide
3.1 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 8.8 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 8.8 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 2: 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
8
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.
3.2 Mount ultrasonic anemometer with
piezoelectric assembly
3.2.1 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 device
performance.

3.2.2 Mounting
You can attach a pole (not included) to a permanent
structure and then attach the sensor package to it (see
Figure 3).
The install hole will accommodate a pole diameter of 1.0
inch (pole not included).
Figure 3: Sensor package mounting diagram 6-1

Make sure the mounting pole is vertical, or very close to
it. Use a level as needed.
1. If optional extension cord is added, connect the
cord to the connector and insert the USB port into
the AC adaptor as Figure 4 show:
