Description
The
Weather Station Suntracer KNX-GPS light
light measures temperature, wind
speed and brightness. It perceives precipitation and receives the GPS signal for time
and position. Furthermore, the exact position of the sun (azimuth and elevation) is cal-
culated on the basis of location coordinates and time.
ATTENTION
The calculation of the position of the sun is optimised for UTC -1...+3.
The device therefore may only be applied within Europe. For other time
zones, please use Suntracer KNX-GPS Weather Station.
All data may be used for the control of switching outputs which depend on threshold
values. The states may be linked by means of AND and OR logic gates. The compact
housing of
Suntracer KNX-GPS light
stores the sensor system, the evaluation elec-
tronics and the electronics of the bus connection.
Functions:
•
Brightness and position of the sun
: The current light intensity is measured
by means of a sensor. At the same time, Suntracer KNX-GPS light calculates
the position of the sun (azimuth and elevation) on the basis of time and location
•
Wind measurement
: The measurement of wind speed is accomplished
electronically and thus noiseless and reliable even in case of hail, snow and
minus temperature. Air swirls and up-draught in the radius of the weather
station are collected, too
•
Precipitation perception
: The surface of the sensor is heated so that only
drops and flakes are recognised as precipitation but not fog or dew. If it stops
raining or snowing, the sensor dries quickly and the precipitation message
ends
•
Temperature measurement
•
Week and calendar time switch
: The weather station receives time and date
from the integrated GPS receiver. The week time switch operates up to 4
different periods each day. With the calendar time switch, you may determine
3 additional periods where the time switch accomplishes up to 2 activations
and deactivations each day. The Switching outputs can be used as
communication objects. The switching times are set by parameter or via
communication objects
•
Switching outputs
for all measured and calculated values (Threshold values
can be set by parameter or via communication objects)
•
8 AND and 8 OR logic gates
with each 4 inputs. Every switching incident as
well as 8 logic inputs (in the form of communication objects) may be used as
inputs for the logic gates. The output of each gate may optionally be configured
as 1 bit or 2 x 8 bits
Configuration is made using the KNX software ETS. The
programme file
(format VD),
the data sheet and the manual can be downloaded from the Elsner Elektronik
homepage on
