Note: This temperature sensor has two
versions: a probe version (WN34S) and a
cabled version (WN34L) as your selection.
The probe sensor is mainly used to test the soil
temperature, while the cabled version is
mainly used to test water temperature.
The two versions will be recognized as the
same sensor type by the software. If you
purchased both, they will share the eight
channels together and the total supported
quantity of the two sensors could not exceed
eight for one receiver.
2.1 Features
Temperature Sensor
Measures temperature with a 3m (10ft)

6
cabled sensor for the cabled version or a
30cm (11.81inch) stainless steel probe
sensor for the probe version.
Extended wireless range up to 300 feet
(100 meters) in open areas.
Transmits readings every 77 seconds.
IP65 waterproof.
LCD display for current reading.
When paired with a GW1000/GW1100
Wi-Fi Gateway:
View temperature reading on the Live Data
page of the WS View app (requires that the
gateway and your phone are using the same
Wi-Fi network).
Up to 8 channels supported. Channel
names can be edited on the app.
Battery level information displayed on the

7
WS View App.
When paired with a Weather Station
Console (HP2551/HP3500/HP3501):
View temperature data in real-time on the
Display.
Up to 8 channels supported. Channel
names can be edited on the console.
When uploaded to Ecowitt Weather Server:
View current temperature data, history
records and graph on the website.
Receive email alerts from the server.
Remote monitoring with smart phone,
laptop, or computer by visiting the website.

3. Setup Guide
3.1 Installing battery
1. Remove the battery door on the back of the
transmitter by removing the screw, as shown in
Figure 2:
Figure 2: Battery installation

9
2. Insert one 1.5V AA battery (be aware of
polarity: flat side of the battery goes to the
spring side of the battery compartment).
The temperature reading will display on the
LCD screen immediately and will normally
update every 77 seconds (the sensor
transmission update period).
Note: If there is no reading on the screen,
make sure the battery is inserted the correct
way or a proper reset happens. Make sure the
battery is inserted correctly. Do not install the
battery backward.
4. Close the battery door by installing the
screw.

4. Sensor Placement
To mount the unit on a wall or wooden beam:
Use a screw (Screw ST D3.2*M2.0*6) to
fix the bracket on the wall, and then insert
the probe through the hole of the bracket,
as shown on figure 3-1:
(cabled version)

11
(probe version)
Figure 3-1: Sensor mounting
Fix the sensor to the bracket with the
Hexagon M12 nut and tighten the screw
as shown on figure 3-2: (hand turn the nut
until firm, and then use a wrench to turn
1/3 ~ 1/2 turn and no more. Do not over
tighten.)

Note:
When installing the soil temperature sensor in
the soil, please do not push the probe into the
soil by holding the main unit body instead of
the probe itself. The unit is fragile between
the probe and main body attachment and can
only withstand a maximum force of 5kg.
Please don’t insert the sensor into corrosive
liquids or hard rock to avoid any damage.
5. Wi-Fi Configuration with gateway
To view the sensor data on your mobile
application and receive email alerts on our
weather server, you need to pair this device
with our GW1000/GW1100 Wi-Fi Gateway or
HP2551/HP3500/HP3501 Weather Station
(each sold separately).

16
5.1 Pair with Gateway
If the GW1000/GW1100 has been in operation,
and you have never had any WN34 sensor
setup before, just power up the sensor and
GW1000/GW1100 will pick the sensor data
automatically.
Note: The gateway can support a maximum of
8 WN34 temperature sensors. Each new sensor
will be recognized as a new channel according
to the Power-on sequence. You may attach a
label to the channel on each sensor for
distinction. The channel name can be edited
both on the app and ecowitt.net (The edited
name on the app will not sync to the
ecowitt.net website, and it should be edited on
your device setup page on ecowitt.net
separately).

17
If you want to use a new WN34 sensor to
replace the old one (already configured on
certain channel), please try the following:
1. Open the Sensor ID page on the WS View
app, and find your old sensor ID.
2. Power off the old sensor and power on the
new sensor.
3. Click Re-register on the Sensor ID page.
Then the new sensor will be learned and the
old sensor will be erased.
5.2 Wi-Fi Connection for the Gateway
For this part, please refer to the manual of the
GW1000/GW1100 Wi-Fi gateway.

18
6. View Online Data with WS View
When the Wi-Fi configuration is done (to tell
the gateway to be hooked to your Wi-Fi
network), your sensor data as well as the
sensor battery voltage information will be
displayed on WS View App at the Live Data
page.

19
Note: It requires your phone and the gateway
must be in the same network when viewing
your sensor live data on the WS View app.
Live data refers to current data received by the
gateway and is not stored on WS View app.

20
However data is always pushed and saved on
www.ecowitt.net cloud (under your
registered account, and it can always be
accessed via your browser.)
Detailed operation instructions can be found in
the GW1000/GW1100 manual.
7. Set EmailAlerts
Once your device is added successfully on the
Ecowitt Weather server, you may set alerts for
the sensor on the website to get email
notifications.
