As the figure shows, it is composed of the conductive type probe, the electronic switch and the frogs sound circuit. It can be used in the detection of the water level of the wells or mines, when the probe touches the groundwater, the light-emitting diode will send out the green light, and the circuit will output the sound of forgs. The circuit is simple and practical, the volume is small and exquisite.
