Part Number - S-WCG-M003
Ultrasonic Wind Speed & Direction Smart Sensor
Compact and rugged with no moving parts, this ultrasonic sensor 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, RX2100, USB Micro Station, H22, 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.
Interested in wireless sensors? The wireless Wind Speed & Direction sensor is available for use with the HOBOnet Field Monitoring System.

|Wind Speed/Gust||Wind Direction|
|Measurement Range||0 to 41.16 m/s (0 to 92.07 mph)||0 to 359 degrees|
|Accuracy||±0.8 m/s (1.79 mph) or ±4% of reading, whichever is greater||0.2 to 3 m/s (0.44–6.7 mph):
>3 m/s (6.7 mph): ±2 degrees
|Resolution||0.4 m/s (0.89 mph)||1 degrees (0 to 359 degrees)|
|Measurement Definition||Wind speed readings are taken every three seconds for the duration of the logging interval
Wind speed: Average speed for the entire logging interval
Gust speed: The highest three-second wind recorded during the logging interval
See Measurement Operation.
