Functions of the Elsner P03/3 Modbus Weather Station, Model 30146

Brightness Measurement for Three Directions

The weather station is equipped with three independent brightness sensors for:

• East,
• South,
• West.

This allows the automation system to accurately analyze sunlight exposure on individual building facades and automatically control:

• Blinds,
• Shutters,
• Use motion detectors to control lighting
• Air conditioning,
• Comfort and energy-saving scenarios

Electronic Wind Measurement

Wind speed is measured electronically—without mechanical components.

Thanks to this:

• Operation is completely silent.
• Measurements remain reliable even during:
  • Hail,
  • Snow,
  • Frost,
  • Adverse weather conditions.

The station also detects:

• Turbulent air movements,
• Local gusts and thermal winds occurring near the building

This effectively protects:

• External blinds,
• Awnings,
• Facade shutters.

External Temperature Measurement

The built-in temperature sensor allows for real-time measurement of ambient temperature.

Data can be utilized by the automation system to control:

• Use binary output modules uts as affordable relays
• Air conditioning,
• Ventilation,
• Heat recovery,
• Energy-saving scenarios.

Heated Precipitation Sensor

The station is equipped with a heated precipitation sensor with a power of 1.2 W.

Thanks to the heating:

• False detections caused by:
  • Fog,
  • Dew,
  • Moisture
• The sensor dries quickly after precipitation ends,
• ensuring stable and precise operation even in difficult weather conditions.
