Hi guys,
I'm building my super incredible multi-tank system..obviously managed with Ferduino...as you probably most of you well know...
Some question for Fernando about level sensors.
In Ferduino code they are used as analog signals, doing things on the basis of the fact that their reading is >400 or <400. For my understanding I have a couple of questions:
- >400 is when the contact is closed (so green led switched ON near its related plug on Ferduino)? or it is exactly the opposite?
- I saw the scheme you published here in the forum for the TPA, where it is possible to see where you have sensors from 1 to 4. my question is: all your sensors are installed in the same way? I mean: when water is over the sensor the contact is closed and when it is below the sensor the contact is open? or some sensors are installed in the opposite way?
thank you so much, as usual.
