Has anyone tried using water level sensors with RO water?
Hello, I'm planning to make an automatic water stopper using solenoids and water level sensors. But the question is will it work if the RO (reverse osmosis) water is a poor conductor, it isn't that clean like distilled water, but the TDS is like 15 so there is still a chance that the sensor will show something or is it just better to buy TDS sensors that are more expensive?

@Dog use a capacitive sensor
I used it
I think you can use it for water
Be careful because I used it in a pot for a plant and the humidity and the soil ruined my sensor oxidating the line for the sensor
most moisture sensors corrode over time. you could try epoxy coating the capacitive types or try the newer types here:
