4.2 Air temperature and humidity
The air temperature is measured by a high accuracy NTC-Resistor. The humidity is measured
by a capacitive humidity sensor. External influence on the measurement (like sun radiation) is
eliminated by a compensation algorithm.
4.3 Air Pressure
The absolute air pressure is measured by an integrated sensor (MEMS) within the device. The
barometric altitude formula is used to calculate the relative air pressure in relation to sea level
(NN) using the GPS altitude (the altitude that can be set by the user in the device).
4.4 Precipitation
Latest radar technology is used to measure precipitation. The precipitation sensor works with
a 24GHz Doppler radar, which measures the drop speed and calculates precipitation quantity
and type by correlating drop size and speed.
4.5 Wind
The wind meter uses a heated thermal element. Depending on the wind speed and direction
the temperature of the thermal element changes. This temperature change is used to calculate
the wind speed and direction.
4.6 Global Radiation
The global radiation is measured by a pyranometer mounted in the top cover of the WS10.
4.7 Position of the sun
The position of the sun is calculated by the geographical position of the weather station plus
the current date and time.
4.8 Brightness
The illuminance is measured from the visible light.
4.9 Twilight
Twilight illuminance is measured by the illuminance sensor driven with a different attenuation.
4.10 Compass
The integrated electronic compass can be used to check the north – south adjustment of the
sensor housing for wind direction measurement. It is also used to calculate the compass
corrected wind direction.
Therefore, it is not necessary to adjust the WS10 to the north.
If there are misdirections in the compass due to surrounding magnetic fields, the electronic
compass can be switched off and manual alignment can be specified instead. See
configuration
4.11 GPS (Global Positioning System)
An integrated GPS-Modul is used to measure the geographical position of the WS10, date and
time.
Device description - 7 -
4.12 UV-Index
The UV-Index is a standard measurement value of the strength of sunburn-producing
ultraviolet (UV) radiation. The UV radiation is measured with an integrates sensor and the UVIndex is calculated.
Note: The measured UV-Index must not be used for medical applications.
UV-Index
Risk
Schutz
0-2
low
A UV Index reading of 0 to 2 means low danger from the
sun's UV rays for the average person.
Wear sunglasses on bright days. If you burn easily, cover up
and use broad spectrum SPF 30+ sunscreen. Bright surfaces,
such as sand, water and snow, will increase UV exposure.
3-5
moderate
A UV Index reading of 3 to 5 means moderate risk of harm
from unprotected sun exposure.
Stay in shade near midday when the sun is strongest. If
outdoors, wear sun protective clothing, a wide-brimmed hat,
and UV-blocking sunglasses. Generously apply broad
spectrum SPF 30+ sunscreen every 2 hours, even on cloudy
days, and after swimming or sweating. Bright surfaces, such
as sand, water and snow, will increase UV exposure.
6-7
high
A UV Index reading of 6 to 7 means high risk of harm from
unprotected sun exposure. Protection against skin and eye
damage is needed.
Reduce time in the sun between 10 a.m. and 4 p.m. If
outdoors, seek shade and wear sun protective clothing, a
wide-brimmed hat, and UV-blocking sunglasses. Generously
apply broad spectrum SPF 30+ sunscreen every 2 hours,
even on cloudy days, and after swimming or sweating. Bright
surfaces, such sand, water and snow, will increase UV
exposure.
8-10
very high
A UV Index reading of 8 to 10 means very high risk of harm
from unprotected sun exposure. Take extra precautions
because unprotected skin and eyes will be damaged and can
burn quickly.
Minimize sun exposure between 10 a.m. and 4 p.m. If
outdoors, seek shade and wear sun protective clothing, a
wide-brimmed hat, and UV-blocking sunglasses. Generously
apply broad spectrum SPF 30+ sunscreen every 2 hours,
even on cloudy days, and after swimming or sweating. Bright
surfaces, such as sand, water and snow, will increase UV
exposure.
≥11
extreme
A UV Index reading of 11 or more means extreme risk of
harm from unprotected sun exposure. Take all precautions
because unprotected skin and eyes can burn in minutes.
Try to avoid sun exposure between 10 a.m. and 4 p.m. If
outdoors, seek shade and wear sun protective clothing, a
wide-brimmed hat, and UV-blocking sunglasses. Generously
apply broad spectrum SPF 30+ sunscreen every 2 hours,
even on cloudy days, and after swimming or sweating. Bright
surfaces, such as sand, water and snow, will increase UV
exposure

7.1 Configuration
After connecting the supply voltage the WS10 will start automatically.
If there is no WiFi configured, the WS10 starts in WiFi access point mode. By using the UMB-
ConfigTool.NET you can now configure the WS10.
Be aware, that the configuration mode is limited to 30 min.
Configuration mode will be indicated by LED blinking green
To ensure a stable WiFi connection you should be within 10m around the WS10 with
your device running the UMB-ConfigTool.NET.
To configure the WS10 you need a WiFi capable device running Windows
®
-PC Software
or Android® operating system and theLufft ConfigTool.NET. The Lufft ConfigTool.NET
can be downloaded on the Lufft internet web site or
installed directly from the Android® Playstore.
Connect your device with the WS10 WiFi access point
SSID: WS10_Wifi-<serial number>
Password: <serial number> (to be found on the label)
Note: During the connection to the WS10 there is no
connection to the Internet possible.

restart with the new parameters.
Connect your device to the local WiFi you configured the WS10 for.
Commissioning - 19 -
Now you should be able to connect to the WS10 through your local WiFi and continue the
configuration of the WS10 if needed.
If you do not need the Wifi connection, please disable the WiFi in the configuration
menu of the ConfigTool.NET. Under WiFi – WiFi you can disable the WiFi.
Due to the integrated electrical compass a manually north alignment is not necessary
and therefore must not be configured.
The complete functionality of the ConfigTool .NET is described in a seperate documentation to
be found on the Lufft internet web site.
7.1.1 Adjustment to the local time zone
The system time (UTC) of the WS10 is adjusted automatically by the GPS-Modul. To adjust
the WS10 to the local time zone where the WS10 is installed, you need to enter the respective
offset value.
Please be aware – the offset value may change with the change of summer- and
wintertime (daylight saving time).
E.g. For central Europe the time zone is UTC +1h (wintertime) and UTC +2h
(summertime). The respective offset would be 3600s or 7200s.
Through the Button in the ConfigTool.NET you get to the configuration menu. Under GPS
– UTC local time offset you may adjust your desired time offset in seconds.
7.1.2 Adjustment of location height
Through the Button in the ConfigTool.NET you get to the configuration menu.
Under GPS – Location height you can select between Manual and Auto configuration. Using
Auto (GPS) mode, WS10 will retrieve the altitude from its internal GPS sensor. In Manuel
mode you can specify your location height manually.
Commissioning - 20 -
7.1.3 Manual adjustment to the north
In rare occasions there is a need to manually adjust the WS10 to the north. This could be the
case if the WS10 is mounted close to a strong magnetic field or large steel constructions.
To manually adjust the WS10 to the north, you must enter the difference in degree between
the WS10 connector and the magnetic north.
Through the Button in the ConfigTool.NET you get to the configuration menu.
Under Wind – Manual angle alignment in degrees you can enter the direction of the WS10.
7.1.4 Wind direction at calm winds
The WS10 offers two ways to report wind direction at calm winds.
1. Freeze – means the WS10 reports the last measured wind direction
2. North – means the WS10 reports 0° as wind direction
Through the Button in the ConfigTool.NET you get to the configuration menu.
Under Wind – Wind direction at inactivity you can make your choice what should be reports
at calm winds.
Commissioning - 21 -
7.1.5 Manual activation of precipitation radar
Because of country individual regulation the precipitation radar is switched of automatically by
a geofencing algorithm in countries where there is no approval.
If you want to manually switch on the precipitation radar, you can use the ConfigTool.NET to
do so.
Through the Button in the ConfigTool.NET you get to the configuration menu.
Under Radar rain sensor – Radio regulations you need to select Manual
and under Manual setting you need to choose the country standard you want to comply to.
Caution
The operation of precipitation radar outside the approved countries is not permitted
by law. The operator acts at his own risk and is responsible for a possible criminal
liability itself. Lufft rejects any liability for the operation of precipitation radar outside
the countries approved by Lufft.
7.1.6 Reset into configuration mode
If the WS10 is due to miss configuration not accessible anymore through the WLAN, you can
reset the WS10 to the configuration mode in two ways.
1. Position a magnet close to the housing where you can read ‘Reed’ on the housing.
2. Connect B+ to Pin 5 of the WS10 connector
Switching to the configuration mode is indicated by a short blue flashing of the status LED.
As long as the WS10 is in configuration mode, this is indicated by a green flashing every 10s
of the status LED.
Please note that configuration mode is only active for 30min.

7.5.3 Modbus
For a simpler integration of WS family Smart Weather Sensors into a PLC environment the
Modbus communication protocol has been made available.
Commissioning - 24 -
Measurement values are mapped to Modbus Input Registers. The range of values available is
basically the same as for the UMB protocol, including different unit systems.
In the interest of simple and safe integration the use of register pairs for floating point values
or 32 bit integers, which is not part of the Modbus standard, has not been applied. All
measurement values are mapped to 16bit integers using suitable scaling factors.
Modbus communication parameter
The Smart Weather Sensor can be configured for MODBUS-RTU or for MODBUS-ASCII.
The base configuration must be done using the UMB Config Tool.
When selecting MODBUS RTU or MODBUS-ASCII with the UMB Config Tool, communication
parameters 19200 Bd, even parity, will be preselected.
Modbus operating modes: MODBUS-RTU, MODBUS-ASCII
Baud rate: 19200 (9600, 4800 or lower)
Interface Setting 8E1, 8N1, 8N2
The Modbus communication has been tested for a poll rate of 1 sec. The proper function
of the Smart Weather Sensor with higher Modbus poll rates has not been tested.
We suggest to set the poll rate to 10 sec or slower, as, with the exception of the channels
„wind speed / wind directions fast“, which are provided for special purposes, the update rate of
the data is >= 10sec. However, for most of the weather data, significant changes should be
expected in the range of minutes.
Addressing
The Modbus address is deducted from the UMB device ID.
A device with UMB device ID 1 also has the UMB address 1, etc..
The valid address range of Modbus from 1 to 247 is smaller than that of the UMB device IDs.
If a UMB device ID > 247 has been selected, the Modbus address will be set to 247.
Modbus functions
The functions of conformance class 0 and 1 have been implemented as far as they are
applicable for the Smart Weather Sensor, i.e. all functions operating on register level.

Function 0x06 Write Holding Register, 0x10 Write Multiple Registers
By writing into the holding registers selected parameters of the Smart Weather Sensor can be
adjusted through Modbus.
Register assignment see 7.5.3.4
Local altitude, compass deviation and averaging intervals are set by writing the new values
into the related registers. Depending on the selected register the value must be scaled by the
factor given in the table:
Example: for compass deviation, the table shows a scaling factor of 10.0. If the deviation is
4.8° a value of 48 shall be written into register 2 (reg.addr. 1).
The transmitted values will be checked for plausibility. Illegal values will not be accepted and
cause a Modbus exception.
When writing the value 0x3247 (12871d) to register no. 8 (reg. addr. 7) the stored absolute
rain amount will be set to 0. Subsequently a device reset will be initiated.
When writing the value 0x3247 (12871d) to register no. 9 (reg. addr. 8) a device reset will be
initiated.
Function 0x04 Read Input Registers
The input registers are containing the measurement values of the Smart Weather Sensor and
the related status information.
The measurement values are mapped to the 16bit registers using scaling factors (0 … max.
65530 for unsigned values, -32762 … 32762 for signed values).
Values 65535 (0xffff) resp. 32767 are used for the indication of erroneous or not available
measurement values. A more detailed specification of the error can be evaluated from the
status registers.
The assignment of values to the available register addresses (0 … 124) has been arranged in
a way so that the user can read the most frequently used data with few (ideally only one)
register block requests
Following blocks have been defined:
• Status information
• Frequently used values which are independent of the unit system (met./ imp.) in use
• Frequently used values in metric units
• Frequently used values in imperial units
• Other measurement values
Commissioning - 26 -
When using the metric unit system, the first three blocks can the supply all data usually
required with one request.
There is no difference in the register assignment between the sub types of the WS family. If,
dependent on the type, some value is not available, this will be indicated by setting the register
to the error value.
For detailed information about measurement ranges, units etc. please refer to the related
description of the UMB.
