Davis® Wind Speed/Direction Smart Sensors are compatible with all HOBO weather station loggers, HOBOware, and HOBOlink. They offer the same ease-of-use as existing Onset Smart Sensors, providing cost-effective HOBO weather stations for projects on a tight budget. The sensors feature a plug-in modular connector for easy installation, and all configuration parameters are stored in the sensor and automatically communicated to the logger, eliminating the need for programming or extensive setup.
The Wind Sensor Set includes Onset's research-grade plug-and-play Wind Speed Smart Sensor and the Wind Direction Smart Sensor. This combination provides average wind speed, highest 3-second wind gust, and average wind direction for the measurement interval. These durable sensors will provide many years of accurate and reliable performance.
NOTE: Mount these on the M-CAA Full Cross Arm for proper sensor spacing for accurate wind measurement in all wind directions.
The cross arm must be mounted on a stable mast, using guy wires as needed to prevent the sensors from vibrating in high winds.
Measure wind speed from 0 to 76 m/s (0 to 170 mph). This smart sensor provides data reporting average wind speed and highest 3 second gust for each logging interval. The starting threshold is 1 m/s (2.2 mph); sensor survives through 170 mph. This model comes with a 3m cable.
The Wind Direction Smart Sensor is a research-grade plug-and-play sensor for measuring and logging wind data. It provides average wind direction for the measurement interval. This highly-durable wind vane has a drip overhang for anti-icing. Its shielded stainless-steel ball bearings and static-dissipating housing provide a long sensor life. The sensor calculates a unit vector average of the wind direction, providing data directly in degrees.
The Ultrasonic Wind Speed and Direction Smart Sensor is compact and rugged with no moving parts. Because this sensor is ultrasonic it is able to measure very low wind speeds, down to 0.4 m/s (compared to 1.0 m/s for our mechanical sensors). As with all Onset smart sensors, this sensor is plug-and-play with HOBO stations (RX3000, USB Micro Station and the U30-NRC). Because it is automatically recognized by HOBO stations, there is no need for programming, resulting in fast and easy deployment. The sensor is powered by its own built-in solar panel.
The HOBOnet Wireless Wind Speed and Direction Sensor records wind speed, wind gust, and wind direction. HOBOnet Wireless Sensors communicate data directly to the RX3000 weather station or pass data through other wireless sensors back to the central station. They are preconfigured and ready to deploy, and data is accessed through HOBOlink, Onset’s innovative cloud-based software platform.
The Wind Monitor is a high resolution wind sensor for air quality applications, that is compatible with Onset's line of research-grade weather stations, including the RX3000, U30-NRC, H21, and H22 systems. When paired with the S-WCB-M003 wind sensor adapter, it offers plug-and-play performance with Onset stations, eliminating the need for programming or complex wiring. It combines low threshold, fast response and excellent fidelity to meet important regulatory standards.

Wind speed is sensed by a lightweight, carbon fiber thermoplastic (CFT), helicoid propeller. The wind direction sensor is a lightweight, balanced vane. The instrument body is UV stabilized plastic with stainless steel and anodized aluminum fittings. The instrument mounts on standard 1 inch pipe.
The Wind Monitor is an accurate and reliable wind sensor specifically designed for the rigors of the marine environment, that is compatible with Onset's line of research-grade weather stations, including the RX3000, U30-NRC, H21, and H22 systems. When paired with the S-WCC-M003 wind sensor adapter, it offers plug-and-play performance with Onset stations, eliminating the need for programming or complex wiring.
The wind speed sensor is a four blade helicoid propeller. Unique transducer produces a pulse signal without electrical contacts or slip rings. The wind direction sensor is a durable molded vane. Vane angle is sensed by a precision potentiometer housed in a sealed chamber. All materials are carefully selected for corrosion resistance and maximum durability in the harsh marine environment. Extremely durable ceramic bearings are used throughout. Stainless steel bearings are used throughout. Special waterproof lubricant further enhances reliability. The instrument mounts on standard 1 inch pipe.
