Hi guys, anyone succeeded in utilising arduino uno on measuring water level with non contact capacitive sensor (resistor with aluminium foil)?
I did such a test a few years ago with a NodeMCU, didn't have an Uno at the time so not with an Uno. It worked. Two strips of aluminium foil taped next to each other on a plastic jar.
Didn't try if there's any effect of difference in conductivity of the water, and if so how much.
