The KNX-GPS weather station measures the temperature, wind speed and luminosity. It detects precipitations and receives the
time and location data through the GPS signal. In addition, it calculates the exact position of the sun (azimuth and elevation)
using the site coordinates and time.
All of the weather data is sent to the bus at regular intervals. This data can be received and operated by other KNX products or a
supervision system that it able to define the thresholds and establish logical combinations from among several quantities to
ultimately control the outputs depending on the threshold values.
The weather station enables direct control of the switch outputs thanks to the pre-defined alarm levels: rain and frost alarm, and 3
wind alarm levels. It can also ensure the shading or heat recovery functions by tracking the position of shutters or the tilt of slats
for blinds.
The sensors, data operation electronics and bus coupler electronics are stored in the compact housing of the KNX-GPS station.
■
Luminosity and sun position
The light intensity is measured using a luminosity sensor. At the same time, the KNX-GPS weather station calculates the position
of the sun (azimuth and elevation) using the time and location.
■
Wind speed measurement
The wind speed electronic record provides quiet and reliable operation, even during hail, snow and minus temperatures.
Turbulence and upslope winds close to the weather station are also recorded. This information is transmitted periodically and can
be used as a wind alarm control.
■
Precipitation detection
The surface of the sensor is heated so that only droplets and flakes are identified as precipitation, thereby disqualifying fog or
thaw. When the rain or snow stops, the sensor dries quickly and indicates the end of precipitation. This information is transmitted
periodically and can be used as a rain alarm control.
■
Temperature recordings
The outdoor temperature is measured using a sensor. This information is transmitted periodically and can primarily be used as a
display or, for example, as a frost alarm control.
■
Operation associated with domovea
The quantities measured (lux °C m/s) can be used by domovea to configure the levels and control the ON/OFF outputs when the
threshold is exceeded.
■
Date and time - GPS function
The weather station receives the date and time via its built-in GPS receiver. This allows it to manage the switch to daylight saving
time between winter and summer.
■
Rain, wind and frost alarms
This function issues an alarm according to the weather data gathered up to a predefined threshold.
There are 3 types of alarms:
-
Rain alarm
-
Frost alarm
-
Wind alarm defined by 3 thresholds (Alarm 1 - 4 m/s, Alarm 2 - 8 m/s, Alarm 3 - 12 m/s)
■
Shading control
This function manages up to 4 facades with several levels of shading depending on the angle of slat blinds or shutter closure.
