Zusammenfassung:	An underground water level monitoring device comprises a controller, a pressure sensor and a GPRS module and further comprises a low-power-consumption power supply management module, a lithium ion battery, a solar cell panel, a conditioning circuit, a relay I and a relay II. The controller is connected with the low-power-consumption power supply management module through a wire. The low-power-consumption power supply management module is connected with the lithium ion battery through a wire. The lithium ion battery is connected with the solar cell panel through a wire. The pressure sensor is connected with the conditioning circuit through a wire. The conditioning circuit is connected with the controller through a wire. The low-power-consumption power supply management module is connected with the relay I through a wire. The relay I is connected with the conditioning circuit through a wire. The low-power-consumption power supply management module is connected with the relay II through a wire. The relay II is connected with the GPRS module through a wire. The controller is connected with the relay I and the relay II through wires respectively. The controller is connected with the GPRS module through a circuit.
