Hobo RXW-T12-xxx – LI-COR

The HOBOnet T12 is a versatile wireless sensor designed to work seamlessly with the HOBOnet system, providing precise measurements of soil moisture (volumetric water content), soil temperature, and electrical conductivity of soil. Built to endure harsh environmental conditions, these robust sensors have a lifespan of up to 10 years, allowing for extended deployment in the field. The sharpened stainless-steel probes make installation straightforward, even in tough soil conditions, while the large volume of influence ensures more accurate soil moisture readings.

Key Features:

• Triple Measurement Capability: Accurately measures soil moisture, soil temperature, and electrical conductivity within a single device.
• Long-lasting Durability: Designed to last up to 10 years in the field, even in extreme conditions.
• Easy Installation: Sharpened stainless-steel probes allow for easy insertion into hard soil and are resistant to damage.
• Large Volume of Influence: Provides better accuracy by covering a large soil volume (1.010 mL) relative to sensor size.
• Advanced Technology: Features 70MHz frequency capacitance technology, minimizing the effects of soil salinity and texture for more reliable data.
• Wireless Connectivity: Communicates via a 900 MHz wireless mesh self-healing network with a signal range of up to 450 to 600 meters. The network can be expanded using HOBOnet wireless repeaters.

HOBOnet System Overview:

The HOBOnet system is a scalable and cost-effective wireless sensor network ideal for web-enabled monitoring of field conditions in applications like crop management, research, and greenhouse operations. The wireless design allows for easy monitoring of multiple points without the need for long cables, reducing the risk of interference and damage from environmental factors. Data from all connected sensors can be accessed through the HOBOlink web service, LI-COR’s cloud-based software platform.

Optional Accessory:

We recommend the TEROS-CLIP verification clip, which offers a convenient way to confirm the operation and accuracy of soil moisture measurements without needing to test the sensor in actual soils.

Technical Specifications:

• Wireless Range: Up to 450-600 meters with up to five hops; extendable with HOBOnet wireless repeaters.
• Power: Rechargeable AA batteries and built-in solar panel.
• Memory: Onboard memory to prevent data loss.
• Environmental Conditions: Suitable for outdoor use, designed to withstand harsh field environments.
• Supported Measurements: Soil moisture, soil temperature, and electrical conductivity.

The Hobo RXW-T12-xxx sensor is an excellent choice for professionals needing reliable and long-term monitoring of soil conditions across various agricultural and environmental applications.
