Embodiment
[0023] Such as figure 1 As shown, the present invention is mainly composed of a single-chip microcomputer, a solenoid valve, a peak clipping circuit, a V / F conversion module and a water level sensor. Wherein, the signal output interface of the water level sensor is connected with the input terminal of the V / F conversion module, which is used to detect the water level in the water feeding pool and output corresponding electrical signals to the V / F conversion module, which needs to be set inside the water feeding pool ;The water level sensor adopts AL200W piezoresistive water level sensor, the AL200W piezoresistive water level sensor can accurately measure the liquid pressure proportional to the liquid level depth, and convert it into a standard electrical signal output, and establish the output signal and liquid depth The linear corresponding relationship, so that the liquid level from the end of the water level sensor to the liquid surface can be measured, and the water volume...
