Steelhead is leading the shift to a true Internet of Things (IoT) data acquisition experience that incorporates low-power, all-in-one, and patented technology.
Mix and match third-party sensor brands and types.
Easily configure to an SDI-12, Modbus RTU over RS-485, and/or Pulse sensors.
The HydraProbe®’s detailed mathematical and signal characterization of the dielectric spectrum helps factor out errors in the soil moisture measurement such as temperature effects, errors due to salinity, and soil type. Low inner-sensor variability means there is no need for sensor-specific calibrations.
Simple to setup, collect, manage, and analyze your data. Use the Steelhead mobile app via Bluetooth or Stevens-Connect to get started.
