Not a bad design. It also fits in surface-mounted sockets.
But it's better to use this type of sensor. Reliable.
Material: P.P
Cable length: 25cm
Contract rating (Max): 10W
Switching voltage (Max): 100VDC
Switching current (Max): 0.5A
Breakdown voltage (Max): 220VDC
Carry current (Max): 1.0A
Contract resistance (Max): 100mĪ©
Temperature rating: -10~+85Ā°C

Where did this brother get such a sensor - I mean, where to look for it???

I bought for the first time at the radio market (120), but later I ordered from eBay. Much cheaper.

Isn't it for 73.98? The infrared ones seem good, but the price is steep.
Patricia1746
That's it! But it costs 30 from the Zhiguli. I'll try it and let you know the pros and cons. It's very tempting... even very, very tempting - but the price...

Electronics, damn... now I'm sitting here, thinking.
(), did I understand correctly that the VAZ ones work on 12V? What Oleg suggested () is 220.
And also - there is some kind of controller left in the timer's box. Judging by the power wires, it is involved. What is its function in your design? Please explain.
I have such a reed switch, but I'm thinking - if there is a choice between 12 and 220, then your scheme is safer. This also needs to be taken into account.

These sensors do not require any voltage to operate. Their task is to open/close a contact. For this, a magnet and a couple of metal plates are sufficient.
The voltage is specified to indicate which network the sensor can close. That is, a 220V sensor can work properly with 12V, but the reverse is unlikely to work without issues.

Colleagues practicing with reed switches - at what angle do they trigger?
Off-topic PS
I found another wonder. I'll post the link, even though it's not exactly a DIY project.

12-24 V.
Powers the cooler - Titan - it stands in the cabinet and works on exhaust.

The title says:
Purpose:
The DR-829r relay is designed to detect the presence of liquids that conduct electric current at the level of the installed detectors.
That is, this device works on the principle of closure due to resistance - in general, washing currents in the aquarium are not needed by anyone - a reef is neither a boiler nor a storage tank - who knows how this will end - there are many options.

You're wrong about these relays... their branded auto-diluted logo works just fine on such a device. I'm currently testing a similar gadget, but it's made by a friend on order. The problem so far is with the electrodes - they don't sell titanium rods here.

The author deserves great thanks for the idea; the self-filling was done in one evening and has been performing its functions perfectly for a month now.
Sherri1320
Not quite that.
In my version, there are significantly fewer accidents.
Samuel6138
Could you please test the device by simply shorting the contacts instead of using water? If this trick works, we can use regular capacitive/angular sensors = no metal, no coated titanium.
Alec9378
Why is titanium necessary?
Jeffrey6189
Nothing is accumulating there. This system has been working for a year already.
Amy9618
I confirm. I bought this device from Sergey - I pour a glass of water from the aquarium into a 20L osmosis canister - that's it, it works without any issues. My daughter, who knows nothing about aquariums, has been managing it on her own for two months now - it's like a traffic light, all the colors speak for themselves. P.S. If you don't add saltwater, on pure osmosis, the electrodes can start to "glitch" somewhere around 1/3 or 1/4 of the length - it starts showing that the water is finished.

In the second version (currently in production), the sensitivity has been increased.
