RXW-WCG-868 HOBOnet Ultrasonic Wind Speed & Direction Sensor

RXW-WCG-868

RXW-WCG-868 HOBOnet Ultrasonic Wind Speed & Direction Sensor

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.

Description

Overview

Wireless ultrasonic wind speed and direction sensor powered by 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 HOBO MicroRX station or transmit data via other wireless sensors to the central station. They are pre-configured and ready to deploy, and data is accessed through HOBOlink, Onset's innovative cloud-based software platform.

Sensor

Wind Speed/Gust Direction

Measuring 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 during the recording interval

Wind Speed: Average speed for the entire recording interval

Gust Speed: Highest three-second wind recorded during the recording interval

See Measurement Operation. The unit vector average is used; Vector components of each wind measurement are calculated every three seconds during the recording interval (see Measurement Operation)
