Designed to withstand harsh environmental conditions, this durable sensor 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 an increased volume of influence provides better results and a more accurate view of soil moisture. The HOBOnet T11 is backed by over 20 years of soil-moisture research and features a trademark 70MHz frequency capacitance technology, minimizing salinity and textural effects.<\/p>\r\n\r\n<p>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\u00ae, Onset's innovative cloud software platform.<\/p>\r\n\r\n<p>We suggest using the Verification Clip (see Compatible Items, below). The <a href=\"\/products\/accessories\/teros-clip\" target=\"_blank\">Verification Clip<\/a> 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.<\/p>\r\n","applications":["Environmental Research & Protection","Climate","Environmental Compliance","Renewable Energy","Green Space","Ecology","Water Resource Management","Aquatic Ecology","Water Quality & Compliance","Hydrology & Groundwater Monitoring","Watershed Management","Wetland & Stormwater","Dam Management","Building Performance","Construction Compliance","Agricultural Monitoring","Agricultural Research","Irrigation & Water","Crop Production","Orchard & Vineyard","Disease and Pest"],"brand":"HOBO","compatible_items":{"Data Logger":{"Web_based_Monitoring_Systems_via_remote_communication":{"items":["RX3000","RX2100"]}},"Accessory":{"Maintenance":{"items":["TEROS-CLIP"]},"Batteries":{"items":["HWSB-LI","HRB-NiMH-2"]}},"Communications":{"Communications":{"items":["RXMOD-RXW-xxx","RXMOD-RXW-900","RXMOD-RXW-868","RXMOD-RXW-922","RXMOD-RXW-921","RXW-RPTR-xxx","RXW-RPTR-900","RXW-RPTR-868","RXW-RPTR-922","RXW-RPTR-921"]}}},"compliance_marks":["Conformit\u00e9 Europ\u00e9ene (CE)","Federal Communications Commission (FCC)","National Communications Commission (NCC)","Regulatory Compliance Mark (RCM)"],"country":"US","customers_also_bought":["RX3000","RXW-THC-xxx","TEROS-CLIP","RX2100"],"field_documents":[{"nid":10746},{"nid":10751},{"nid":10771}],"environment":["Outdoor"],"faqs":[{"q":"Are any installation tools available?","a":"<p>Yes.
