基于自建模技术的电容土壤水分传感器研究

Study of a Capacitance-Based Self Model-Establishing Sensor for Measuring Water Content of Soil

基于自建模技术研究了一种快速传感、低成本、高可靠性的土壤含水量传感器。土壤水分的快速传感受土壤类型影响很大 ,利用自建模技术 ,能有效地降低传感器受土壤类型的影响 ,将该模型内置于传感器中在农村得到广泛应用。

A fast sensing, low cost and reliable sensor based on self model-establishing for measuring water content in soil is studied. The type of the soil influences greatly on the measurement results of the water content. A self model-establishing method is used to reduce the influence of soil types. Because of self establishing model embedded into the sensor, the sensor for measuring water content of soil can be used widely in countryside.
