Adding isolation to water sensors
I put off releasing more about the water quality sensors I have been working on in the background (Mini, and Leo versions of eC, DO, ORP, etc…) so that I could test some single IC solutions that I saw from AD early test are very promising, and I seem to be on a solid path to both Dataline and Power isolation. This will be huge news for those stuck with “other” noisey eC sensors causing problems with pH and DO readings. This will also solve most of the ground loop and mains noise issues some people have with pH sensor in larger water bodies or those with mains powered pumps in them.
I wanted to put up a brief post to talk about this and also mention that I should have reference designs up shortly and then some first revisions will show up a couple weeks later (looks like on track for a mid Aug release).
So sit tight and with any luck (Please Murphy, I hear someone needs your help somewhere else lol) we’ll have isolated sensors soon!
