Wireless Wind Sensor – WMO-class precision & ultra-low power : MeteoWind IoT Pro | BARANI DESIGN

The MeteoWind IoT Pro is a compact wireless wind speed and wind direction sensor engineered to exceed WMO, NWS/NOAA, DWD and MEASNET measurement standards. Designed for all-weather performance, it provides reliable, high-precision meteorological data with ultra-low power consumption and no moving components requiring electrical connections or battery replacement.

Its aerodynamic elliptical cup design, derived from the proven MeteoWind 2 architecture, ensures superb snow shedding, high linearity and exceptional resistance to hail, dirt and adverse weather conditions. The MeteoWind IoT Pro is built from rugged anodized aluminum, providing long-term durability for demanding professional wind measurement applications.

Advantages :

• Faster response than ultrasonic anemometers with a time constant under 0.3 s at 4 m/s.
• No dead spot wind direction measurement with magnetic sensor accuracy better than 3°.
• Very low starting speed below 0.25 m/s.
• High reliability and data availability in extreme weather conditions.
• Wireless Sigfox or LoRaWAN communication using robust Star-on-Star IoT network architecture.
• Ultra-low power with a solar-powered Li-ion system supporting 4+ months of operation without sunlight.
• All-metal anodized aluminum body for corrosion resistance and long-term stability.
• Patented flat elliptical cups for high-linearity aerodynamics and winter-optimized snow shedding.
• Compact design that increases accuracy and reduces snow accumulation on the rotor.

Key Features :

• Wind speed range: 0–85 m/s with gust data collected at 4 Hz.
• Wind speed accuracy: ±0.2 m/s or 1% of reading (whichever is greater).
• Wind direction range: 0–360° with 2° accuracy and 1° resolution.
• Linearity: R² > 0.99995 for precise response.
• Distance constant: < 1 m for wind speed and < 0.5 m for direction.
• Wireless communication: LoRaWAN or Sigfox, NB-IoT planned.
• Power consumption: only 350 μA for combined wind speed/direction and transmission.
• Survival wind speed: above 85 m/s (306 km/h, 190 mph).
• Environmental rating: IP65W for the anemometer and IP67W for the wireless module.
• Operating conditions: −33 °C to +80 °C, 0–100 % RH.
• Dimensions: rotor Ø164 mm, vane radius 111 mm, height 272 mm.
• Weight: 210 g (anemometer), 500 g (wireless module).
• Includes a 90° stainless steel mounting arm with dual M6 mounting screws.

Typical Applications :

• Professional weather stations requiring WMO-compliant accuracy.
• Smart-city and IoT environmental networks deploying distributed wind sensors.
• Renewable energy monitoring (wind farms, solar fields).
• Agricultural and agro-meteorological platforms.
• Coastal and maritime monitoring.
• Industrial environmental and safety systems.
• Remote, autonomous measurement sites with minimal maintenance.

Why choose the MeteoWind IoT Pro :

MeteoWind IoT Pro is selected for its WMO-class meteorological accuracy, long-lasting mechanical robustness and ultra-low-power wireless operation. It offers superior all-weather performance compared to ultrasonic alternatives, especially in winter conditions where snow and ice accumulation can disrupt measurements.

Its combination of precise wind speed and direction tracking, rugged aluminum construction and maintenance-free wireless architecture makes it an ideal choice for professionals seeking reliable long-term wind data in harsh Canadian environments.
