Knock sensors are piezo-electric sensors that respond to vibrations in a certain narrow frequency range.

All you will get is a quick electrical pulse out of them, so you would need a small circuit to detect a pulse over a certain level, and then 'latch' it (in the electronics sense of the word) to light an indicator. It could also be set to not latch in a fault (knock) on one or a few knocks, to avoid nuisance indications. So, yes, doable for sure.

Well lookie here: Caspers Electronics Knock Gauges 102003

NICE, that's super cool! Definitely gonna have to do something like that for my next build. Much better than trying to tune optimal timing by ear (listening for knock) or paying money and a couple hours of time tuning on a dyno. With one of those and a wideband O2 AFR readout there would be no excuse not to get your car tuned perfectly.
