To obtain the best possible wireless
emissions (high range) it is advisable not to
place the rain sensor directly on the ground.
By mounting the sensor about 3 feet (1m)
above the ground the danger of soiling
(especially the solar cells) is reduced.
After screwing on the lower part to the base
secure the upper part as follows:
There is a bar magnet centrally located on
the side on the counting rocker for the water
level in the base. The bar magnet initiates
the counting pulses to the electronics. The
upper part of the housing can now be placed
so that the solar cell is on the same side as
the magnet, with the electronic part directly
opposite it, with the three catches fitting
neatly into the holding devices in the lower
part. Finally turn the upper part gently anti-
clockwise until it securely slots into holding
devices of the lower part.
The rain sensor is then ready for operation.
As a test pour a little water gently into the funnel. The amount collected will then be converted in
the base unit to inches, litres/m
2
or mm and displayed.

Brightness sensor WS 2510-19
The brightness sensor detects the brightness at the current location in a range between 0 and
200000 lux. It is powered by an integral solar cell and also has a fixed address. To mount the
sensor, the plastic point is inserted on one side of the aluminum tube supplied and the sensor is
fitted on the other side of the tube. The sensor can now be inserted into the ground. Depending
on the firmness of the ground, the earth spike should be inserted so that the sensor is about 8-12
inches (20-30 cm) above the ground to avoid it becoming dirty due to mud splashing up onto it.
The sensor should be turned so that the solar cell points to the south. The location must be free
from shadows and the sun able to shine directly onto the measuring head. The sensor must be
mounted vertically with the measuring head at the top.
2.3.4
Addressing of the temperature/humidity sensors WS 2510-22, WS 2510-25, and
WS 2510-27
The outdoor sensor concept enables the
concurrent deployment of up to eight outdoor
sensors, whose data can be selected by the user
to appear in the top right hand field of the display.
Each sensor in the system is assigned a sensor
address, which enables the receiver to integrate
the sensor into the total system without any
problems. Each sensor delivered is set to sensor
1. The programmable allocation is clear from the
diagram.
The addressing can be self-generated by means
of coding bridges on the conductive side of the
sensor board. To do this on the WS 2510-25
unscrew the protective bell housing on the sensor housing and open the housing by removing the
screws on the rear.
The WS 2510-22/27 types only require the housing rear wall to be unscrewed.
The coding bridges must then be set according to the address table.
2.3.5
WS 2510-22 temperature/humidity sensor
The WS 2510-22 contains a temperature and a humidity sensor. This sensor is freely
addressable for displaying within the display field at the top right of the display (see display
overview on page 4). The addressing can be set individually according to section 2.3.4. Since it is
exclusively battery operated this sensor is suitable for use in (dark) inner rooms such as a
garage, a wine cellar or loft.
2.3.6
WS 2510-27 temperature/humidity sensor
The WS 2510-27 requires two AA alkaline batteries for operation. It enables the recording of
garden, pond or ground temperatures or similar by means of an encapsulated temperature
sensor, remotely connected to the electronics by a 9.84 foot (3 m) cable. Humidity around the WS
2510-27 casing can also be measured.
This sensor can also be freely addressed for displaying within the display field at the top of the
display (see display overview on page 4). The addressing can be set individually according to
section 2.3.4.
Now you can mount or position the electronics housing at the required location and place the
temperature sensor on or in the required object.
2.3.7
WS 2510-25 temperature/humidity outdoor sensor
The WS 2510-25 outdoor sensor enables the transmission of the temperature and humidity at the
sensor location.
This sensor can also be freely addressed for displaying within the display field at the top of the
display (see display overview on page 4). All WS 2510-25 sensors are set at the factory to sensor
1. In accordance with section 2.3.4. individual addressing is also possible.
The sensor should be mounted on the north or west side as meteorological temperature
recording normally takes place “in shadow ”. It can also be placed at other locations if desired.
You only need to make sure that the solar cell that provides the sensor with power is permanently
aligned towards the light. The sensor must not be shaded by dense obstructions such as leaves,
etc., which could impair the power supply from the solar cell. However, the solar cell does not
have to be exposed to direct sunlight. The ambient brightness is sufficient to charge the battery.
A possible location for installation is under the eaves of the roof.
The sensor is designed for wall and mast mounting and should be mounted as follows: Attach the
sensor wall bracket either exactly vertically to a wall using the four screws, or to a mast using the
securing clamp provided.
Position the sensor on the wall bracket and screw the two parts together using the screw
provided.
When doing this, the large protective bell housing must be at the top and the solar cell must be
pointing towards the light.
During the hours of darkness and periods of bad weather with relatively little sunlight an internal
battery system, which is charged by the solar cell during periods of sunshine, provides the power
for the sensor.
2.3.8
Information on the storage of solar cell powered outdoor sensors
These sensors receive their operating voltage from a solar cell that charges an internal battery to
provide power for periods of darkness and bad weather.
If one of these sensors is out of action for some time and does not receive any light this has no
affect on the internal battery, provided the magnets designed to activate the operating voltage are
removed.
Therefore the sensor can be stored for several months in its packaging, for example.
