Overview

The HOBOnet T12 is a wireless sensor that works with the HOBOnet system to not only provide advanced soil moisture (volumetric water content) measurements 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. Featuring the METER TEROS 12 soil moisture and temperature sensor, the HOBOnet T12 is backed by over 20 years of soil moisture research and leverages METER’s 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 TEROS Verification Clip, available from the Compatible Items tab.  TEROS Verification Clip provides a convenient way to confirm the operation and soil moisture accuracy of the HOBOnet T11 and T12 sensors. Attaching this clip to a TEROS sensor provides a known soil moisture level for verifying measurement accuracy without needing to go through the work of testing the sensor in actual soils, which would normally require weighing soil samples and drying them in an oven. 

Highlighted Features
