Wireless Wind Speed & Direction Sensor

  • Compact analog design with high dirt resistance.
  • Faster response than ultrasonic anemometers with < 0.3 s time constant at only 4 m/s.
  • Higher data availability than ultrasonic anemometers in extreme weather.
  • Robust dual-arm reinforced cup design with field serviceable components using standard tools.
  • Flat elliptical cup shape offers superb snow shedding and very good hail resistance.
  • All-metal anodized-aluminum body and wind vane design.
  • Ultra-low power for wireless applications.

Compact anemometer and wind direction vane sensor with ultra-low power & no dead spot. Meets all World Meteorological Organization (WMO) measurement standards of measurement.
No wires to connect or batteries to change, no connectors to break. Featuring SigFox or LoRaWAN wireless Star-on-Star network technology for reliable and redundant data transmission.
Elliptical cup design of the proven MeteoWind 2 is used to offer superb measurement qualities in a compact and cost-effective instrument made from anodized aluminum.

Other Features

• Uses IoT-Wind, an open communication protocol which permits direct connection to any Internet-of-Things (IoT) application and cloud platform.
• Magnetic wind vane sensor offers better than 3° accuracy.
• Anodized aluminum body and wind vane guarantee robustness, corrosion protection and longevity.
• Patented design of flat elliptic cups offers high-linearity
• Aerodynamics and superb winter snow shedding even without heating.
• High response, linearity and accuracy with a very low < 1.5 m distance constant.
