Soil Moisture Data Loggers & Sensors (+Soil Temperature)

Onset’s offering of research-grade weather stations and compatible Smart sensors for accurate measurement of moisture in soil, without any programming or extensive user setup.

    RXW-T12-xxx

    The HOBOnet T12 is a wireless sensor that works with the HOBOnet system to not only provide advanced soil moisture measurements (volumetric water content) with better accuracy and precision, but also measure soil temperature and electrical conductivity. Designed to withstand harsh environmental conditions, these durable sensors last up to 10 years, so you can leave them in the field for extended periods of time. Sharpened stainless-steel probe tips make installation easy, even in hard soil, and a large volume of influence provides more accurate results. The HOBOnet T12 is backed by over 20 years of soil-moisture research and features a trademark 70MHz frequency capacitance technology, minimizing salinity and textural effects. 

    The HOBOnet system is a cost-effective and scalable wireless sensor network for web-enabled monitoring of field conditions for applications such as crop management, research, and greenhouse operations. And because it’s wireless, you can deploy a network of sensors to easily monitor multiple points with a single system, while avoiding the risk of long cables that can interfere with field operations and are potentially vulnerable to nearby lightning strikes. Sensors are easily linked to the network, and data can be accessed through HOBOlink®, Onset's innovative cloud-based software platform.

    We recommend using the Verification Clip (see Compatible Items, below). The Verification Clip provides a convenient way to confirm the operation and soil-moisture accuracy of HOBOnet T11 and T12 sensors. Attaching this clip to a sensor provides a known soil moisture level for verifying measurement accuracy, without having to test the sensor in actual soils, which normally requires weighing soil samples and drying them in an oven.

    RXW-GPx-xxx

    The HOBOnet Multi-Depth Soil Moisture Sensor is a wireless sensor that works with the HOBOnet system to measure soil moisture and soil temperature at multiple depths with a single probe, for fast and easy installation. This durable sensor is available in three probe lengths for measurements from 45 cm (18 in) to 90 cm (35 in) deep.

    Featuring GroPoint’s TDT5 technology with patented antenna design, these sensors measure soil moisture along the entire length of each probe segment, resulting in the largest volume of influence per measurement section. A high frequency of pulses per measurement provides precise and consistent soil moisture data.

    We recommend using the optional pilot rod and slide hammer for quick and easy installation. Onset offers two options for the pilot rod, the PILOT-ROD4 (28”) for use with the three- and four-segment sensors (RXW-GP3 and RXW-GP4), and the PILOT-ROD6 (40”) for use with the six-segment sensor (RXW-GP6).

    RXW-T21-xxx

    The HOBOnet T21 is a wireless sensor that works with the HOBOnet system to measure both soil temperature and soil water potential, a more accurate way to measure how much water is available to plants. The HOBOnet T21 Sensor is designed to withstand harsh environmental conditions, and it does not require calibration for different soil types or salinity. The HOBOnet T21 is calibrated in a chamber system that allows the T21 set calibration points from -10KPa to -80KPa. With its durable epoxy coating, you can be confident these sensors can be deployed in the ground for long periods, while providing data you can trust.
