    Product Description

    Onset HOBOnet Wind Speed and Direction Sensor - RXW-WCF-900

    **Please Note!** A complete system requires at least one HOBO RX3000 Remote Monitoring Station , a HOBOnet Wireless Manager , and a HOBOnet Wireless Sensor. HOBOnet Wireless Repeaters can be added to extend the range.

    Overview
    The HOBOnet Wireless Wind Speed and Direction Sensor records wind speed, wind gust, and wind direction. HOBOnet Wireless Sensors communicate data directly to the 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 HOBOlink, Onset’s innovative cloud-based software platform.

    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 per RX3000
    • Sinmple 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
    In what environment does this data logger operate?
    This sensor operates in an outdoor environment.

    What measurements does this data logger support?
    The RXW-WCF-xxx sensor supports the following measurements:     Evapotranspiration and Wind

    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
