• Soil moisture (volumetric water content) and soil temperature measurements with one device
• Sensor lasts up to 10 years in the field
• Largest volume of influence (1010 mL) relative to sensor size, resulting in more accurate soil moisture measurements
• Easy installation with sharpened stainless-steel probes that are more resistant to damage/deterioration
• Less sensor-to-sensor variability

The HOBOnet TEROS 11 is a wireless sensor that works with the HOBOnet system to not only measure soil moisture (volumetric water content) with better accuracy and precision but also provide soil temperature measurements. 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 probes make installation easy, even in hard soil, and a large volume of influence provides better results and a more accurate view of soil moisture.

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 suggest 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 TEROS 11 and TEROS 12 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.
