Soil sensor

The soil sensor comprises a pedestal (110), a first detection part (120), a second detection part (130) and a circuit part (170). A first signal line (121) of the first detection unit is a wiring pattern in which a wiring pattern projected onto installation surfaces (111, 113) of the pedestal is annular. A first GND line (122) of the first detection unit is disposed at a distance from the first signal line, and a wiring pattern of the first GND line of the first detection unit, which is projected onto the mounting surface of the pedestal, is disposed in a region surrounded by a wiring pattern of the first signal line, which is projected onto the mounting surface. The second detection unit is disposed in a region surrounded by the wiring pattern of the first GND line projected onto the mounting surface of the pedestal. 土壤传感器包含台座(110)、第一检测部(120)、第二检测部(130)及电路部(170)。第一检测部的第一信号线(121)是投影到台座的设置面(111、113)上的配线图案为环状的配线图案。第一检测部的第一GND线(122)相对于第一信号线隔开间隔地配置，并且第一检测部的第一GND线的投影到台座的设置面上的配线图案被配置在由第一信号线的投影到设置面上的配线图案包围的区域。第二检测部被
