摘要：
A novel and useful sensor and sensing system employs a transmission electrode which provides a length of transmission electrode that is greater than the physical length of the sensor, allowing for the effective and accurate determination of the moisture content of a volume of material using high-frequency measurement methods. The construction of the sensor allows the sensor to be directly inserted into the material, without requiring excavation or backfilling of the sensors in the material. The sensor can be employed as part of a sensing system, with one or more sensors preferably being managed by a field node, which in turn, interoperates with a system master node.
