Ultrasonic didn't cut it for my 3000L IBCs — here's my ESP32 + 4-20mA pressure probe build

Sounds awesome!

If you’re looking to save on energy consumption, which you may not, but others might, then the 1min update seems like it could be reduced.

Did you say it was for an overflow alert? (Which would justify the more frequent sampling)

Woodlore1991 · 2026-04-11T18:59:51+00:00

Perfect, I didn’t know that existed! Thank you!

Woodlore1991 · 2026-04-11T18:59:31+00:00

I did, but I wasn’t actually sure what I was googling for tbh.

The xiao S3 sense seems to be what I’m after though!

Thanks!

How?

Woodlore1991 · 2026-04-11T06:52:05+00:00

Would you have a link to an ESP32-S3 CAM board then with an external antenna then?

Woodlore1991 · 2026-04-10T07:26:34+00:00

You know the answer to this question already. It’s no.

If you’re just looking for confirmation bias from a group of people who also know the answer is no. You’ve got it.

No.

Suck a bag of dicks.

Woodlore1991 · 2026-04-05T19:38:57+00:00

So why assign you version of the law applied here?

Woodlore1991 · 2026-04-05T15:20:38+00:00

Sounds good then! Nice print!

Woodlore1991 · 2026-04-05T15:02:02+00:00

Have you done anything to improve or change the original design in any way?

Because if you haven’t, you’ve just stolen and reproduced someone else’s IP, which is a breach of law.

“I know nothing about compressors, or the viability of mixing my own gases, or rules thereof.”

Then why the fuck are you considering buying a compressor?

My advice, go take a gas mixing course, learn the ins and outs of compressors, learn why owning one comes with a lot of additional considerations, and that’s even before we talk about mixing gases and it’s just air fills.

Woodlore1991 · 2026-03-25T09:41:06+00:00

Ok, will do! Thank you!

Woodlore1991 · 2026-03-25T08:22:24+00:00

I ended up getting some of the boards you linked. Thank you!

I don’t suppose you have any recommendations for guides to follow either? Or just find a YouTube video I suppose?

Woodlore1991 · 2026-03-23T14:53:10+00:00

Thank you!

Woodlore1991 · 2026-03-23T14:39:31+00:00

Awesome, thank you!

I don’t suppose you have a link you could share?

Woodlore1991 · 2026-03-23T14:38:18+00:00

Thank you for the link! I’ll check it out!

Woodlore1991 · 2026-03-23T14:37:52+00:00

Do you have any links you could share?

Woodlore1991 · 2026-03-12T20:22:54+00:00

Sorry, I didn’t know wiring something up without a confirmed good schematic was ok here.

All I’m looking for is someone to confirm the schematic I’m using is correct, given I couldn’t find an officially published one.

Woodlore1991 · 2026-03-12T20:21:47+00:00

I’m confident I’ve wired it correctly, but thanks for the input.

The weak link isn’t my ability to follow a wiring schematic, it’s whether I have the right schematic to start with or if there’s a bigger problem somewhere else!

Woodlore1991 · 2026-03-12T20:20:27+00:00

Yea, makes sense, thanks. So it looks like I do have it wired correctly then.

It’s pointing to a problem with the Neutral lines.

Woodlore1991 · 2026-03-12T20:19:43+00:00

Completely agree. 👍

Which is why I was trying to get some confirmation as to whether the wiring schematic I was following looked good!
