The green color indicates very clearly where the water level was.

Instead of running current through the sensor 247, only turn on the power when you want to take a reading.

Share Report Save level 2 nano, uno, mega2560 4 years ago What about adding a sacrificial metal, like the zinc bits on a boat motor 3 Share Report Save level 2 Original Poster 4 years ago bal00, How do you turn the power onoff to a sensor (at least this sensor) if you have it hardwired to 5V GND Can I provide the 5V it needs via another GPIO pin that I turn onoff in the code Lastly, in theory, if I did this, i would just prolong its life--not really fix the problem long-term.

Is there another sensor that will provide the same reading but wo this symptom thx 1 Share Report Save Continue this thread level 1 4 years ago I believe thats a pretty common problem with resistive water sensors.

I was shopping for soil moisture monitors a while back and came across some that were capacitive if I remember right that were supposed to avoid this issue.

As the other person mentioned, a workaround is to only apply voltage occasionally and briefly.

Share Report Save level 1 4 years ago In addition to the excellent suggestion to power off the sensor when not reading, it might also be possible to attach a sacrificial anode like an iron nail.

See: 2 Share Report Save level 2 nano, uno, mega2560 4 years ago This is what I was thinking.

I dont know why they dont do that 2 Share Report Save level 1 4 years ago Im not familiar with that exact type of water sensor, but it may be possible to coat it in a thin layer of varnish and drive it with pulses, basically using it as a capacitive sensor.

Of course, the readout gets more complicated this way.

Share Report Save level 1 4 years ago I am having the same problem.

I tried to use a delay that just messed up how everything worked.

Im just ordering these to solve the problem.
