Get Accurate Readings on Wind Speed and Direction in Seconds

A wireless sensor that works with HOBOnet to record wind speed, wind gust, and wind direction. HOBOnet wireless sensors communicate data directly to the HOBO RX3000 or the HOBO MicroRX 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.

This sensor measures wind speed and direction and is designed to work with the HOBOnet (HOBO® RX) Wireless Sensor Network in which data is transmitted wirelessly from the sensor mote across the network to the station and then uploaded to HOBOlink® web-based software. With HOBOlink, you can monitor sensor readings, view graphs, set up alarms, download data, and more.


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 or 336 data channels per HOBO RX station
  • 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


Important Information

A complete system requires at least one HOBO RX3000 Remote Monitoring Station, a HOBOnet Wireless Manager, and a HOBOnet Wireless Sensor, OR one HOBO MicroRX Station (which has an integrated HOBOnet Wireless Manager) and a HOBOnet Wireless Sensor. HOBOnet Wireless Repeaters (RXW-RPTR-xxx or RXW-RPTR-B-xxx) can be added to extend the range.

Technical Information

Sensor

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 (see Measurement Operation)
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 (see Measurement Operation)
