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.
- Compact and rugged with no moving parts
- Plug-and-play with HOBO stations
- No starting threshold – suitable for low wind speeds
- No wind direction dead band – accurate wind data in all directions
- Powered by its own built-in solar panel
- Affordably priced

What measurements does this sensor support?
The S-WCG-M003 sensor supports the following measurement: Wind
|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
