Produktnummer: RXW-WCF-868 Kategori:

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.

Highlighted Features

Sensor Features

  • Provides average wind speed, highest 3-second wind gust, and average wind direction for the measurement interval
  • Designed to meet World Meteorological Organization (WMO) guidelines

Wireless Features

  • 900 MHz wireless mesh self-healing technology
  • 450 to 600 meter (1,500 to 2,000 feet) wireless range and up to five hops
  • Up to 50 wireless sensors per RX3000
  • Simple button-push to join the HOBOnet wireless network
  • Onboard memory to ensure no data loss
  • Powered by rechargeable AA batteries and built-in solar panel

In what environment does this sensor operate?

This sensor operates in an outdoor environment.

What measurements does this sensor support?

The RXW-WCF-xxx sensor supports the following measurements: Evapotranspiration and Wind


A complete system requires at least one HOBO RX3000 Remote Monitoring Station, a HOBOnet Wireless Manager (RXMOD-RXW-xxx), and a HOBOnet Wireless SensorHOBOnet Wireless Repeaters (RX-RPTR-xxx) can be added to extend the range.







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) 1.4 degrees (0 to 355 degrees)
Starting Threshold ≤1 m/sec (2.2 mph) 1 m/sec (2.2 mph)
Turning Radius 108 mm (4.25 in.) Approximately 135 mm (5.25 in.)
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
Unit vector averaging used; vector components for each wind measurement are calculated every three seconds for duration of logging interval
