greathow:
using MKR GSM 1400
I'm creating a remote sensor project that would detect the presence of water and ping a server.My actual sensor is essentially two metal contacts hooked to 3.3v and ground. When I submerge the sensor in water, the voltage increases, but only slightly.
Thanks!
Doubt you will get much help with the new MKR range of Arduinos at this stage.
I would think the voltage would decrease if you would do that,
unless you use two different metals and the water is acidic.
Did you use intenal pull up on the pin (assuming the MKR has that), or an external pull up resisor.
