OVERVIEW
Access accurate wind speed data on LI-COR’s powerful cloud-based Platform
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 the LI-COR Cloud IoT platform (formerly HOBOlink).

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.

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) Operating Temperature Range Without Icing -15°C to 55°C (5°F to 131°F) Wireless Mote
