I am working on a water sensor (to check if there is any water in the bilge). What I have read is that water sensor corrode because of electrolysis (which occurs when you set 3v on a water sensor). To reduce the corrosion you can use a digital out pin to power the sensor and turn it on when you want to take a measurement (you could measure every minute).
An alternative is to use a capacitive sensor to prevent electrolysis. I am not sure if we can use one of the 'touch' pins of an ESP32 for that.
Any suggestions or experiences that someone cares to share about the issue above or water sensors in general?
