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 UV-
Index 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

Caution
Fall hazard while working in heights
For installation, only approved and tested aids (ladder, steps, etc.) may
be used.
All applicable regulations for work in heights must be observed.
Caution
Hazard of falling objects.
Make sure the device is mounted correctly and save.
During installation make sure no objects can fall down.
Important notices for installing
Installation and commissioning may only be carried out by adequately qualified
specialists .
Never measure or touch parts that are under voltage.
Observe technical data, storage and operating conditions.
The intended location is outdoors. The device must not be operated in closed rooms.
The building-side holding device must be sufficiently dimensioned and firmly anchored.
The device must be secured in such a way that there are no objects, trees or other
objects in the immediate vicinity that could affect the acquisition of the measured data.
The direct measuring range in front of the device must be kept clear of all obstacles in
any case.
All work must be carried out when the device is de-energized. Only connect the power
supply to the mains once all assembly work has been completed correctly.
The cables to and from the device must be fastened in such a way that no tension is
exerted on the plug connection during operation.
Lay the cables so that they can not be damaged.
Lay the cables so that nobody can trip over them.
To ensure a reliable rain radar measurement, the WS10 must be at least 8 m apart.
The following tools are required for installation:
•fork or ring spanner SW10

To achieve a correct measurement of global radiation, make sure the WS 10 is in all
directions horizontally aligned.

Montage - 16 -
To ensure the correct functionality of the WS10 the notes below concerning the place
of installation must be followed:
•Free sight to the sky –for the correct function of the GPS module and the
precipitation measurement the WS10 must have a free sight to the sky.
•To ensure correct measurements of any kind of sun imposed radiation make sure
that there is never shade on the WS10.
•To ensure correct wind measurements there should be no bigger obstacle (tree,
building, etc.) within 5m around the WS10.
Not following the above mentioned notes may lead to wrong measurements.
6.2 Connections
The WS 10 is to be supplied with a direct voltage of typ. 24 VDC (9-36VDC). The power
supply unit used must be approved for the operation of devices with protection class III
(SELV).
The power supply must serve at least 35W @ 24V. The power connection must be fused by a
2.5A (slow-blow) fuse.
The connecting cable must be resistant to UV radiation. The cable must have an external
diameter of 4-6mm and a wire gauge of at least 0,3mm².

Only used for Wi-Fi AP mode
The device has a half-duplex, 2-wire RS485 interface for configuration, measured value query
and firmware update.
Positive voltage (+Vin 9..36V) at the configuration pin forces the WS10 into Wi-fi access point
mode. This is independent of any other setting within the WS10 configuration.
