Hello all. Simple question for a newbie. I wish to control a solenoid valve for a water pump that runs on propane gas (LPG). The solenoid valve is normally closed. The water pump is used for irrigation/fertigation where the pump must run for fixed amount of time ex: (30min, 45min 60min etc) In a perfect world, I would set an analog timer for 45 min for example, start the engine and the valve would stay open for that 45 min, the valve would that shut and the engine would die and be ready for another its next task.
Only have access to car battery. I looked into omron H3Y 12v timer, can this be achieved with the 0-60 min dial and a simple on/off switch to activate the valve at the beginning? I looked into programmable electronic system but seems a bit complicated for application where the duration changes constantly.
This will be run mostly by my father and a dial with number and switch would be complicated enough for him. Thank you all for your input, all this electronic is not my field of expertise and I am sure someone here will have great input for me.
