In vertical sectors such as wind power generation, aviation safety, smart meteorology, industrial environmental monitoring, and precision agriculture, system integrators, IoT solution providers, project contractors, and engineering companies have an increasing demand for fast-responding, long-term stable, and maintenance-free wind field data. The NiuBoL Ultrasonic Wind Speed and Direction Sensor (typical model NBL-W-21GUWS) uses the Time-of-Flight measurement principle as its core, achieving fully digital detection with no moving parts, delivering industrial-grade accuracy and open communication interfaces. It has become the preferred wind field sensing-layer component for numerous B2B partners building wind power SCADA extensions, airport AWOS systems, regional automatic weather stations, and environmental monitoring networks.

The NiuBoL Ultrasonic Wind Speed and Direction Sensor employs a four-path or multi-path ultrasonic probe array (N-S, E-W directional pairs). It calculates wind vectors by measuring the propagation time difference of high-frequency pulses (>20kHz) in the downwind and upwind directions:
Wind Speed Calculation: Δt = (L / (c - v_cosθ)) - (L / (c + v_cosθ)), where L is path length, c is speed of sound, v is wind speed component; temperature compensation eliminates sound speed drift.
Wind Direction Calculation: Based on multi-path time-difference vector synthesis, achieving full 0~359° coverage.
Compared to traditional mechanical three-cup/vane anemometers, this technology delivers the following engineering advantages:
No mechanical wear or inertial delay, MTBF >50,000 hours, service life up to 10+ years.
Millisecond-level response (typical<100ms), accurately capturing gusts, turbulence, and wind shear.
All-weather operation: IP65 protection, -20~80℃ working range (optional 3W heating function), resistant to freezing, dust, and salt spray corrosion.
Low start-up threshold and high resolution: 0.01 m/s wind speed resolution, suitable for low wind speed and high turbulence scenarios.
