I have been trying to make an EC Meter using arduino following the instructions from this website: https://www.instructables.com/id/Arduino-Water-Pollution-Monitor/
I tested the probe by making an LED glow but when it comes to the readings, I'm getting 5V or numbers very close to 5V for any liquid that I use. I've tried a number of different things to figure out what's wrong but the end result is still the same. Could anyone help me with this?
Thank you.


Post details of your project (not the images in the link, images of YOUR project).

Which liquids did you try?

That's anyway a VERY crude EC sensor, will only give very rough results.
