HOBOnet Wind Speed and Direction Sensor

A wireless sensor that works with HOBOnet to record wind speed, wind gust, and wind direction.

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 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.

Features

Sensor Features

Provides average wind speed, highest 3-second wind gust, and average wind direction for the measurement interval
Designed to meet World Meteorological Organization (WMO) guidelines

Wireless Features

900 MHz wireless mesh self-healing technology
450 to 600 meter (1,500 to 2,000 feet) wireless range and up to five hops
Up to 50 wireless sensors or 336 data channels per HOBO RX station
Simple button-push to join the HOBOnet wireless network
Onboard memory to ensure no data loss
Powered by rechargeable AA batteries and built-in solar panel

Specifications

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
