  • S-SMD-M005

    Measure soil moisture over a large volume of soil with the affordably-priced 10HS Soil Moisture Smart Sensor. This sensor integrates the field-proven 10HS Sensor and a 12-bit A/D, providing ±3% accuracy in most soils conditions, and ±2% accuracy with soil-specific calibration. The 10cm probes measure soil moisture over a larger volume of soil which helps to average out any soil variability. Readings are provided directly in volumetric water content. This sensor's high frequency design gives it a low sensitivity to salinity and textural effects and a wide measurement range.

  • T-WNB-3Y-208-P

    The WattNode sensor provides accurate kWh measurement at a low cost to meet your needs for sub-metering, net-metering, energy management, and performance contracting applications.

    This WattNode kWh Transducer works with Magnelab AC Current Transformers and a Pulse Input Adapter, or a HOBO® Data Node pulse input port to provide True RMS kilowatt hours of energy used, even for loads with non-sinusoidal waveforms. Because these sensors tie directly into the line, they should be used only by qualified personnel. This model supports up to 3 separate 120 VAC single-phase branch circuits or individual 120 VAC phases of a 3-phase wye-connection 208/240 VAC circuit.

  • RMYOUNG-05106

    The Wind Monitor is an accurate and reliable wind sensor specifically designed for the rigors of the marine environment, that is compatible with Onset's line of research-grade weather stations, including the RX3000, U30-NRC, H21, and H22 systems. When paired with the S-WCC-M003 wind sensor adapter, it offers plug-and-play performance with Onset stations, eliminating the need for programming or complex wiring.

    The wind speed sensor is a four blade helicoid propeller. Unique transducer produces a pulse signal without electrical contacts or slip rings. The wind direction sensor is a durable molded vane. Vane angle is sensed by a precision potentiometer housed in a sealed chamber. All materials are carefully selected for corrosion resistance and maximum durability in the harsh marine environment. Extremely durable ceramic bearings are used throughout. Stainless steel bearings are used throughout. Special waterproof lubricant further enhances reliability. The instrument mounts on standard 1 inch pipe.
