Generally how it works already:
There is a pump with an engine, that pulls up water from deep underground. Around a meter deep beneath the territory - a system of plastic pipes, with pressure control. They are connected to a small tank for about 200-300 litres in volume for about a meter off the ground. When the pressure drops from the first (lower) tank, controller enables the engine to pump more water into the system until it reaches certain point
And here's the issue that needs to be resolved - there's a second tank present. It is connected with the first one, and lifted off the ground for about 2 - 2.5 metres high and gets water supply directly through a separate tube from the top. The problem is, it has no sort of digital or analogue sensors. Whenever the lever/ledge (however you call it) is opened to pass the water supply, and it doesn't have any sort of control, water starts to overflow through the top and just continues to poor until you manually remove the power supply from the engine inside (let's call "Control room" with all the relays related to irrigation control system)
Task itself - need to create a way to either close the tube somehow whenever pressure reaches the certain point (I can mount a mechanical blocker for a plastic tube if needed) or connect it to existing system of relays as additional buffer or controller to turn off the engine whenever the pressure has reached it's pique in first lower and second higher tank
If is needed, I can draw a quick map, but if there isn't - the controller room is located right at the entrance to the territory, and both tanks are about 40 metres away from there diagonally (the whole territory is 600 square metres)
To connect I may use simply a loooooong wire for a direct current of electricity, or come up with a Wi-Fi or radio module for a relay if needed
And also the person who wishes this project to be done doesn't want to install floating pressure or water sensors inside the tank for some reason and much prefer to install something inside of the tube that sends water up which will determine the pressure and the level needed. No idea how to pull this up either
Here's the second upper tank
"Control room" (no idea how else to call it). To the left is the power source, to the center are multiple relays, and the control panel of irrigation system is to the right
Dismantled irrigation contoller
And controller to the right just enables the irrigation system at 21:00 o'clock
I'm an amateur at the moment in electronics generally, so if you were to explain stuff, I would like to receive a caveman level of descriptions. I do have certain knowledge in code, how to control arduino, how to send signals, connect to the board itself, but overall picture of how the whole system should work and stuff I would actually need is out of my reach, I understand nearly nothing
I would really appretiate a lot any help on that matter, this would be my examination project
