we've been failing to create some logic that recognises when something's happened from sensor traces & keeps a count - eg: how many brew-ups today … the blips in the traces can be quite small, but quite distinct - easily counted manually, but how to do it automagically, and how to keep a count ??
ditto, extrapolating current trends to predict when something might happen - eg: to warn we might be flooded in two hours …
anyone successfully done such things, by any chance ??

PS: sort of thing we've tried, for the first, is : Sensor => direct & via longish Filter to Differential Amplifier => Thresholds to determine up or down => direct & via longish Delay to an AND gate, and direct & via a NOT gate to another AND gate, to determine if it was a blip or a change in level …
NB: in the case of the second, it's not just a case of a rising level - because water comes & goes, and it's the difference between the two that makes for trouble !
