| Zusammenfassung: | The utility model discloses a soil water level layering detection device which comprises a control box, a conductive column and a sampling circuit, the control box is connected to the top end of the conductive column, a row of vertically distributed detection contacts are arranged on the periphery of the conductive column, each detection contact is of a conductive structure, each detection contact is connected to the conductive column in an insulating mode, and the sampling circuit is connected to the control box. Each detection contact is connected with a corresponding sampling resistor in the sampling circuit, a plurality of sampling resistors in the sampling circuit are connected in parallel and then are connected in series with the positive electrode of the power supply battery through the sampling resistors, the negative electrode of the power supply battery is connected with the conductive column, and a water level detection sensor in the sampling circuit is connected to the sampling resistors.
