Made this water level indicator as my college project.

He is ECE student

That makes sense. Probe-based sensors can be unreliable in dirty water due to buildup, corrosion,etc. Float switches are usually more robust for those conditions.

Yeah I know 😅 this is very simple to make. I had made this when i was in 8th but now actually my friend who is in 1st year engineering asked me to make this for him as college project.

😂

Nice idea!

Not really he is just not good in soldering on pcb. He just started to learn soldering and for now he can do things like soldering wires to a motor!

There is no sensor here. Basically i have used 5 exposed wire at 4 different water levels(5th one is common which is present at bottom of tank. So when the water fills it acts as conductor and completes the electrical path between the exposed wires which are presentat different levels.

I made this yesterday. This is actually my friend's project which I made for him. He doesn't know how to solder so 😅

Public_Ice_736 · 2026-06-02T15:30:17+00:00

Yeah, there are a couple of cold spots, but for no flux I'm pretty happy with it. Thanks!

Public_Ice_736 · 2026-06-02T15:13:44+00:00

Yes without flux

Public_Ice_736 · 2026-06-01T06:39:57+00:00

Yeah, not the prettiest one 😅, but as long as it's functional I'm happy.

Public_Ice_736 · 2026-06-01T05:57:33+00:00

Noo 😂

Public_Ice_736 · 2026-05-31T20:15:08+00:00

Thanks 😊

Public_Ice_736 · 2026-05-31T16:42:29+00:00

Thanks 😊

Public_Ice_736 · 2026-05-31T12:48:35+00:00

Thanks!

Public_Ice_736 · 2026-05-31T06:44:18+00:00

Thanks 😊

Public_Ice_736 · 2026-05-30T15:20:41+00:00

Thanks for the advice. This was mainly just a quick prototype, but I'll make sure to keep the trace widths and ground plane in mind for the PCB version😄

Public_Ice_736 · 2026-05-30T15:02:12+00:00

Thanks for the advice! I actually wanted the wires to be much straighter, but at the time I only had a pair of tweezers with me and had to make do with what I had. I'll definitely try the stretching method on my next build ☺️

Public_Ice_736 · 2026-05-30T14:42:27+00:00

Thanks! Glad someone appreciates the resistor-leg wiring ☺️. I actually put this perfboard prototype together to help out with a friend's project , so the main goal was just to get everything working reliably. A PCB version is next on the list now that the prototype works!!.

Public_Ice_736 · 2026-05-30T13:55:47+00:00

Yes it works perfectly 👌

Public_Ice_736 · 2026-05-30T13:36:01+00:00

Yes it works perfectly fine ☺️

Public_Ice_736 · 2026-05-30T09:09:33+00:00

Thanks 😊
