Great video and idea 👍 Unfortunately, the title is a bit misleading, because it is not directly about cooling an aquarium, but to fill it automatically with water.

[@spassantechnik]

Thank you. Yes, you are right. But cooling the aquarium with a fan is easy. To automatically and reliably refill it with water, on the other hand, is not so easy. Unfortunately, fill up water is not a good term for a video, so I cheated a little here :-)

[@chuchitosoiyo5441]

Vielen dank für die tolle Idee und Anleitung 👍

[@spassantechnik]

Sehr gerne :-) Hast Du es selbst nachgebaut, funktioniert alles soweit!?

[@spassantechnik]

Bitte schaut nach der aktuellsten Sketch-Version. Ich habe noch ein paar Bugfixes gemacht. Die neueste Version ist 2.0 Please check for the latest Sketch version. I have made a few more bug fixes. The latest version is 2.0

Is the version 2 sketch shared in your google drive link?

[@spassantechnik]

@@manongloyd Yes, it is. Check the header of the file: SonicWaveAquaRefiller v2.0 Copyright 2021-2022, Torsten Jäger

[@massimobagnetti4548]

does it still work fine?

[@spassantechnik]

Yes, works flawlessly. But of course I can't guarantee here that it works perfectly for everyone. If you use a faulty sensor, for example, the software can't work properly either.

[@massimobagnetti4548]

@@spassantechnik but if one put transparent plexiglass to protect the sensor would it work anyway or would it disturb the sensor?

[@spassantechnik]

This does not work. The plexiglass will reflect the ultra sonic. But you could try with cling film. It is thin enough. But for me it works without protection. If the sensor has enough distance to the water surface, there should be no problem.
