@Kokosnoot good solution. I remember the discussion in the early days of MySensors. I've powered the radio's for most of my sensors from the 3.3v regulator on the arduino board and for me that works perfect. But for my latest designs I decided to add a separate ams regulator for my radio's like the guys suggested in the beginning. Because you basically want the on board regulator to power the mcu only.

@sundberg84 said in Trying to design MySensors PCB / Fritzing: @kokosnoot MySensors kicad library: https://github.com/mysensors-kicad I managed to install that one with a bit of effort last weekend. However, inspired by bgunnarb I am already trying again for 40minutes to get a DHT11 footprint properly working, but failing thus far. There seems to be some in: https://github.com/KiCad/kicad-footprints/tree/master/Sensor.pretty but KiCad does not appreciate that as a library, (the default is to work from github.com/kicad/Capacitors_SMD.pretty for example, but those are all archived pages) I manually tried adding https://github.com/KiCad/kicad-footprints/tree/master/Sensor.pretty - similar as the other libraries (type Github, etc) but just get a "ZIP error"... Maybe I should try a nightly build instead of the stable 5.0.2. Edit: Just got it to work by downloading the entire 5.1.0 footprint library locally, and pointing to the [..]\footprints\Sensor.pretty file. Inspired by someone else with the same issue: https://forum.kicad.info/t/personal-footprints-via-on-demand-github-plugin-error-reading-zip-local-header/11777 . Hopefully this info might help someone else at some point!

Impressive @Kokosnoot!

Ah, I did have mixed feelings about the alternating. I also don't know what happens with ions when water moves down after watering some plants. I did came across this page (in Dutch, but code in English) which kind of shows a very simple example of using the CD74H4067 multiplexer: http://12volt.kloppenburgweb.nl/een-garduino/. It might be a good thing to see how it performs and come up with something alternative if really needed. I was also thinking of adding some glue to the parts exposed to air. Thanks again!

@gohan Indeed... See e.g. my experience here: https://forum.mysensors.org/topic/2890/chinese-rubbish-or-is-it
