3 of 9 sensors "saturating"
Hi there! I managed to connect and plot the signal from 9 of these sensors. They seem to work fine, except for the last three of them which are kind of saturating. In the screen attached you can see the spikes when I dip the working sensors in water, the central one seems to be not functioning for s...
