    The HOBOnet Wireless Temperature and Relative Humidity Sensor provides a cost-effective and scalable solution for web-enabled monitoring of air temperature and humidity. HOBOnet Wireless Sensors communicate data directly to the RX 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 Featuures

    • High accuracy: ± 0.2°C (± 0.36°F) and ± 2.5% RH 
    • Robust RH sensor withstands extended use in high-humidity environments

    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 RX Station
    • Simple button-push to join the HOBOnet wireless network
    • Onboard memory to ensure no data loss
    • Powered by 2 user-replaceable lithium AA batteries


    Impotant Information

    Includes lithium batteries. A complete system requires a HOBO MicroRX Station, which has an integrated HOBOnet Wireless Manager, and a HOBOnet Wireless Sensor. HOBOnet Wireless Repeater (RXW-RPTR-B-xxx) can be added to extend the range of both system options.
