Yes I'd think twice about long term submersion of electronics.
As you say, unless you suspend it in a block of clear resin, it's unlikely you'll achieve 100% water resistance - and then you still potentially have the issue of condensation, heat variations etc. as IIRC tropical* tanks tend to have the water quite warm?
I would have thought the display will remain fairly clear if pressed right up against the glass on the back of the tank, and it'll give the fish something to look at too :-)
Yeah, tropical, the pump and heater manage ok but they are designed from the outset to be submerged, but behind is fine, have ordered a couple of four line ones, they are so cheap, £5.69, in fact most of the stuff for this stuff is cheap these days, in the 90s, last time i had the urge for doing electronics, stuff like this was expensive, Ebay and Amazon are a godsend, the starter kit for Arduino is marvellous, thirty quid and it includes so much stuff, amazing present for technically inclined kids.As you say, unless you suspend it in a block of clear resin, it's unlikely you'll achieve 100% water resistance - and then you still potentially have the issue of condensation, heat variations etc. as IIRC tropical* tanks tend to have the water quite warm?

- Assuming your tank is tropical!
have got it up and running to sense the temp, display it and produce an audible noise if it goes out of bounds.
All a bit breadboard based for now but still lots of work to do on the functionality.
Next steps are to get it texting me and perhaps make it so it can run if the mains drops out as that is the main cause of the temp dropping I expect so it is cock all use if it goes off.

Cool, will give that a go.
Have got a cheapy GSM module, that is my next task, getting it to text me.
its a long term project, may take a while, cant understand why when I work in IT on databases which is driving me mad, why this is so therapeutic as it is not a million miles off, i think it is perhaps I exist in chaos due to lack of resource, so this I get to do at my own pace to my own standards. Should really spend some time on a CV and have a change of scenery, maybe a job with more than four DBA's to 600 odd DB servers.
