Compatible with all HOBO weather station loggers, HOBOware, and HOBOlink. This sensor offers the same ease-of-use as existing Onset Smart Sensors, providing cost-effective HOBO weather stations for projects on a tight budget. Features 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.

  • Designed to meet World Meteorological Organization (WMO) guidelines

Also available in a wireless model for use with the HOBOnet Field Monitoring System.

In what environment does this sensor operate?

What measurements does this sensor support?

The S-WCF-M003 sensor supports the following measurement: Wind

Wind Speed/Gust Wind Direction
Measurement Range 0 to 76 m/sec (0 to 170 mph) 0 to 355 degrees
Accuracy ±1.1 m/sec (±2 mph) or ±5% of reading, whichever is greater ±7 degrees
Resolution 0.5 m/sec (1.1 mph) 1 degrees (0 to 355 degrees)
Starting Threshold €°¤1 m/sec (2.2 mph) 1 m/sec (2.2 mph)
Measurement Definition Cup revolutions are accumulated 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.
