Re: Another water pump automation project (suggestions ?)

Through the top lid. The inlet pipes at the top are not caulked in place, so there's plenty of room around it for air to get it. Since this is not for drinking, it doesn't matter too much if nasties...

Re: Another water pump automation project (suggestions ?)

Yeah, I'm not sure how the chap was planning to get those floats inside the tanks, since I knew from the very start, just by looking at them, that they only have a very small lid, unless maybe he...

Re: Another water pump automation project (suggestions ?)

I once encountered a magnetic level sensor of the same description in an ironing station. It was used to sense when the water level in the tank dropped too low or if the tank was removed entirely. It...

Re: Another water pump automation project (suggestions ?)

That's how I would've done it from the very start, TBH: connect the two together at the bottom. Come to think of it, now that I look at it better, I think the same effect could be achieved by simply...

Re: Another water pump automation project (suggestions ?)

THIS big. A common sight around here. I think they're 100L each. The valves shall go where those manual valves are, either before or after them. You can see how the fill pipes run to the top.

Re: Another water pump automation project (suggestions ?)

In this case, we're not going DIY though, since the guy already bought (and possibly installed) the float switches I showed.

One possible issue I see with your idea is that it only works for...

Re: Another water pump automation project (suggestions ?)

No, I don't think so: even though I haven't actually seen the setup myself, the guy told me the water inlet sits above the tank, so it's never submerged.



Correct. Said check valve may have...

Re: Another water pump automation project (suggestions ?)

I thought of this method, but this would require TWO switches per tank: one to latch the relay, the other to UN-latch it when it's full, since one SPDT is not enough, at least not without some...

Re: Another water pump automation project (suggestions ?)

I began sourcing some parts for this project, at least to get the basic form off the ground and someone was right: I'm indeed unable to find contactors with a coil voltage of 24VDC - only 24VAC, so...

Re: Another water pump automation project (suggestions ?)

True - the tried and tested way would be a proper PLC-based system and those CAN get pricey, at least for this guy's demands, which are fairly small, since it's his own homestead so to say - it's not...

Re: Another water pump automation project (suggestions ?)

Even less than that: do it purely using relays and buttons at first and then add the "brains". I'll of course plan ahead and prepare the necessary connection points for where a PLC or whatever would...

Re: Another water pump automation project (suggestions ?)

The run timer is a good idea indeed, assuming the tanks fill up at the same rate each time and they're not being drained at the same time by whatever they're connected to, which would also affect how...

Re: Another water pump automation project (suggestions ?)

Some sort of pressure switch or flow meter could prevent that, though at the moment that's of no concern to me.

Thumbs up Re: Another water pump automation project (suggestions ?)

I found something that looks promising here (https://cache.industry.siemens.com/dl/files/041/109741041/att_924628/v1/logo_system_manual_en-US_en-US.pdf?download=true). I haven't looked too deep into...

Re: Another water pump automation project (suggestions ?)

This is precisely why I launched this thread - to hear what others have used and what they may suggest hardware-wise for a small project like this. It's not a powerhouse at the end of the day.

Re: Another water pump automation project (suggestions ?)

Correct, which is why I cannot be bothered to cobble up something from scratch again. We're going OTS this time.

Yes, it was mostly speculative. I was curious to hear how others would tackle such a job.

Re: Another water pump automation project (suggestions ?)

Because people want to upgrade and automate the process :D

I'm afraid a Raspberry Pi would be too much work and too fragile of a product.

Re: Another water pump automation project (suggestions ?)

From what I understand, the setup is already in use, just not automated, so we're in charge of doing only that. I won't be altering any of the existing pipework. I have not seen it personally - my...

Talking Re: Another water pump automation project (suggestions ?)

Let's review then:

At the moment there's nothing there: it's all done manually, though you're right: some sort of local control panel will need to be implemented using a couple of buttons and a...

Talking Another water pump automation project (suggestions ?)

Good day folks. Some of you may recall that a while ago I was struggling to put together what I considered to be a very basic automation for a water supply system. It didn't work out the way I...

Re: Using car key fob as generic remote control

Again, it's not about using the car as a receiver, since it's too far from anything (I live in in an apartment complex, so it's down in the parking lot) - it's about using the car's fob as a remote...

Re: Using car key fob as generic remote control

Ok, I just had a go with these RXB6 modules and I get absolutely nothing out of them. The program the chap shows in his article (https://alex-hhh.github.io/2018/05/arduino-433mhz-receiver.html)...
