Hi together,
how does the Minilogger with digital input works internally? Does it measure a resistance for detection of open / closed connector (passive digital signal) or does it measure a voltage on the input from an active high / low signal (e. g. 3.3V and 0V)?
And where are the trigger level?
The application behind is a simple water detector with two metal connectors that detects water between. So can I use such a water detector directly with the Minilogger or do I need some active power to supply waterdetection?
