Overview

The HOBOnet Wireless Ultrasonic Wind Speed & Direction Sensor is compact and rugged with no moving parts. Because this sensor is ultrasonic it can measure very low wind speeds, down to 0.4 m/s (compared to 1.0 m/s for our mechanical sensors). HOBOnet Wireless Sensors communicate data directly to the HOBO 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.

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):
±4 degrees
>3 m/s (6.7 mph): ±2 degrees
Resolution 0.4 m/s (0.89 mph) 1 degree (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.
Unit vector averaging used; vector components for each wind measurement are calculated every three seconds for duration of logging interval (see Measurement Operation)

Battery Type/
Power Source
Sensor: Photovoltaic panel, LIFEP04 3.2 V -600 mAh battery
Mote: Two AA 1.2 V rechargeable NiMH batteries powered by built-in solar panel or two AA 1.5 V lithium batteries for operating conditions of -40 to 70°C (-40 to 158°F)
Battery Life With NiMH batteries: Typical 3-5 years when operated in the temperature range -20° to 40°C (-4°F to 104°F) and positioned toward the sun (see Deployment and Mounting), operation outside this range will reduce the battery service life
