What's In The Box:

  HOBOnet Leaf Wetness sensor

  Zip ties and screws for mounting

Provides accurate leaf wetness data for a variety of growing and research applications. This preconfigured, ready-to deploy sensor requires no painting or coating, uses a capacitive grid that is less sensitive to surface residues than resistive grid-based sensors, and comes preconditioned for long-term stability and consistent measurements between sensors.

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. Data is accessed through HOBOlink, Onset's innovative cloud software platform.
