HOBOnet Ultrasonic Wind Speed & Direction Sensor
$1,250.00 USD
A wireless ultrasonic wind speed & direction sensor that works with HOBOnet; capable of measuring very low wind speeds (down to 0.4 m/s).
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.
Overview
A wireless ultrasonic wind speed & direction sensor that works with HOBOnet. Compact and rugged, with no moving parts, this ultrasonic sensor 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 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 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 degreesResolution 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)

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)
-
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
With lithium batteries: 1 year, typical use
