Design a New Circuit?

After some consideration we came up with another plan. We could build a circuit to use a current transformer to output pulses in direct relation to the current flow. We could connect a variable voltage current transformer connected to a voltage-to-frequency converter. This frequency could then be converted to a connection pulse, as the rain input needed. The advantages of this design were primarily that we eliminated the physical aspects and everything would be solid state. A good idea, but it would take someone a good deal of time to design the circuit, build the circuit, and calibrate it. From the beginning we had hoped to come up with a simple design that a homeowner or turbine installer could do easily themselves. Back to the drawing board.
