Hi,
I have a problem with my design and I need some input.
S1 is located near the bottom of a half-full tank of water. S2 is near the top. At power-up, S1 is CLOSED, S2 is OPEN. When the water rises to close S2, the pump needs to turn ON. It should stay ON until the water level drops to open S1. The pump should then remain OFF until the water rises to close S2. Repeat as necessary.
I have come up with designs for water sensing, motor-control, and a power supply, but I keep getting stuck on the logic. Can I use the Set/Reset inputs on a 4013 to do this? With some NAND conditioning on the inputs, shouldn't this work?
Attached is a .gif drawing. Thank you.
