Ultrasonic Wind Speed Sensor Compact Low Cost Small Meteorological Transmitter

Ultra-fine 0.01 m/s resolution captures subtle wind speed variations across the complete measurement range, supporting both calm-condition monitoring and high-wind industrial safety applications.

Wind direction accuracy of plus or minus 3 degrees with 1 degree resolution enables precise directional data for bridge safety, marine navigation, and urban environmental monitoring applications.

Four ultrasonic terminals are positioned upside-down, blocking precipitation and particulate buildup on probe surfaces that would otherwise introduce measurement errors in outdoor.

RS485 variant draws only 0.12W, making it the lowest-power option in Renke's wind sensor lineup and ideally suited for solar or battery-powered remote monitoring deployments.

Begins measuring from 0.5 m/s, capturing very light breezes that cup-and-vane sensors with higher mechanical starting thresholds would miss entirely in calm environments.

Structurally rated to survive wind gusts up to 75 m/s without damage, ensuring sensor integrity through typhoons, hurricanes, and severe industrial wind events without replacement.

Optional internal electronic compass removes any directional alignment constraint during mounting, enabling accurate wind direction output on ships, vehicles, and any mobile platform.

Full omnidirectional detection with 1 second update cycle simultaneously captures wind speed and direction without angular blind spots common in mechanical cup-and-vane combinations.

Add-on temperature and pressure modules expand the single anemometer into a compact multi-parameter weather node without requiring additional housings, brackets, or wiring infrastructure.

Each unit is fully calibrated before shipment and ready for immediate deployment, with no field calibration equipment, reference wind sources, or recalibration procedures needed after installation.
