A sensor assembly includes a housing and multiple sensor array segments. A first sensor array segment includes an antenna. A second sensor array segment has a soil temperature sensor, an electrical conductivity (EC) sensor, a moisture sensor, an ion-sensitive field effect transistor (ISFET) nitrate sensor for detecting nitrates in adjacent soil, an ISFET phosphate sensor for detecting phosphates in adjacent soil, an ISFET potassium sensor for detecting potassium in adjacent soil, and an ISFET pH sensor for detecting pH in adjacent soil, and a reference electrode electrically coupled to the first sensor array segment and to the second sensor array segment. The first sensor array segment and the reference electrode can be disposed on opposite sides of the second sensor array segment.
传感器组件包括一个外壳和多个传感器阵列部分。第一个传感器阵列部分包括一个天线。第二传感器阵列段有一个土壤温度传感器、一个电导率(EC)传感器、一个湿度传感器、一个用于检测邻近土壤中硝酸盐含量的离子敏感场效应晶体管(ISFET)硝酸盐传感器、一个用于检测邻近土壤中磷酸盐含量的离子敏感场效应晶体管磷酸盐传感器、一个用于检测邻近土壤中钾含量的离子敏感场效应晶体管钾传感器和一个用于检测邻近土壤中 pH 值的离子敏感场效应晶体管 pH 传感器,以及一个与第一传感器阵列段和第二传感器阵列段电耦合的参比电极。第一传感器阵列区段和参比电极可布置在第二传感器阵列区段的相对两侧。
