Rain sensor for reliable precipitation detection

The Rainswitch 1000 R GI is a rain sensor designed for applications where precipitation is required as a control signal. The solution targets use cases in building automation, safety-related systems, and industrial environments where weather-dependent processes need to be automated.

Reliable detection and standardized signal output
The sensor continuously detects precipitation and transmits its status via a potential-free contact. This type of signal output allows standardized integration into higher-level systems while maintaining electrical isolation between sensing and control layers.

By using a binary output signal, the device can be directly connected to existing control architectures without the need for additional interfaces or protocol converters. This reduces integration effort and simplifies deployment in established automation environments.

Flexible integration across system environments
The sensor is connected via a binary input, enabling its use across a wide range of systems. These include smart home applications as well as technical building systems, such as automated roof window controls that respond to rainfall.

It can also be integrated into programmable logic controllers (PLC), smoke and heat exhaust ventilation (SHEV) systems, and KNX-based installations. This flexibility supports its role within a digital supply chain in building automation, where sensor data drives automated decision-making processes.

Relevance for building and safety applications
In safety-critical systems, such as SHEV installations or automated opening mechanisms, reliable precipitation detection is essential to prevent malfunctions or damage. The sensor provides a robust input signal that can be processed in real time.

Its straightforward integration and standardized signaling make it suitable for both new installations and retrofitting of existing systems.
