Allright I need to create a water pump controller that....once turned on activates a solid state 120v relay(powering the pump), till the tank reaches a certain level...using electrodes,or IR or something??
(NOT A FLOAT SWITCH) to detect water level....once level is reached it turns OFF the 120v relay and starts a countdown timer......which i need to adjust from 2-12hours (potentiometer maybe???) once countdown timer reaches 0 it turns the 120v relay back ON, powering the pump till desired water level is reached.........etc
all i know is how too assemle this type of thing from a schemeatic...i need help with circuit design parts needed etc...
