Weather stations

The KNX weather stations from arcus-eds GmbH provide precise, maintenance-free recording of local weather and sun position data for your modern building automation. Thanks to the integrated GPS module, the system automatically receives exact time and location information. Based on the date, sun position, wind, and solar radiation, the system enables completely demand-driven control of shading systems, lighting, and irrigation systems. The combination of weather station and KNX coupling module works entirely without moving mechanical parts thanks to ultrasound and radar technology, making it absolutely wear-free.

Depending on your requirements, different versions are available that can be flexibly integrated into your KNX network:

The All-in-One Solution: KNX Weather Station Combination WS1-US-GPS(-PM)

This powerful combination of a high-tech weather station and a KNX coupling module with a GPS receiver covers the seamless monitoring of all relevant environmental factors.

• Precise Wind Measurement: Ultrasound sensors record the exact wind speed as well as the wind direction.
• Comprehensive Indoor and Outdoor Climate: Reliable measurement of temperature and humidity.
• Modern Precipitation Analysis: An integrated radar determines rain intensity and cumulative rain volume, with a counter reading that can be flexibly reset at any time via a KNX object.
• Energy Management via Solar Radiation: Measurement of solar radiation and cumulative solar radiation with an automatic daily reset at 00:00.
• Particulate Matter Monitoring (Model WS1-US-GPS-PM): Additional recording of particulate matter pollution in particle sizes PM1, PM2.5, and PM10 for optimal health management.
• Exact Location and Time Data: The coupling module provides local longitude and latitude, brightness, as well as the current date and time.

From these parameters, the system provides valuable derived values directly on the KNX bus. These include absolute humidity, dew point temperature, gust wind speeds, averaged wind values (over 2 and 10 minutes), and wind strength in Beaufort.

The Compact Control Center: SK10L-GPS-THL

For applications where no external weather station is required, the stand-alone SK10L-GPS-THL device offers a highly efficient alternative. It combines core functions of climate and position data recording in a compact housing:

• Measurement of temperature and humidity
• GPS-based local longitude and latitude
• Recording of ambient brightness
• Automatic provision of date and time

Intelligent Logic Functions in All Device Variants

Both the WS1 combinations and the SK10L-GPS-THL feature integrated software functions that eliminate the need for external logic modules:

• Precise Astro Function: Exact calculation of the sun's position (azimuth and elevation angle) for optimal slat tracking and shading.
• Integrated Timers: Year, week, and day timers for automated processes, as well as dedicated switching objects for day, night, and twilight.
• Sector Control: 6 freely parameterizable sectors for tailored sun position calculation depending on the building structure.
