H-Tronic 1115275 Sensor de lluvia con contacto de relé libre de potencial

The H-Tronic 1115275 is a rain sensor with a potential-free relay contact, ideal for automating systems based on precipitation detection. It reliably detects rain and snow, making it suitable for applications such as garden irrigation control, awning protection, and home automation.

Advantages

The sensor uses conductive measurement for accurate detection and offers adjustable sensitivity via a potentiometer. A status LED indicates relay state, and the potential-free changeover contact allows flexible integration with various control systems.

• Garden irrigation systems
• Awning and blind control
• Weather stations
• Home automation projects
