HOBOnet Wind Speed and Direction Sensor

$838.00

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.

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
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
