Brief description of the drawings
Fig. 1 is circuit diagram of the present utility model.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
As shown in figure 1, the automatic pumping control circuit of this triode teaching, including the first water-level detecting line (1), second
