I have a project involving the detection of the presence of water in a cylindrical transparent plastic container (diameter=25cm)
And I cannot put any device inside, so I was thinking of using and IR LED and IR sensor so do you think this is possible ?
How can I make the difference when the container is empty (contains air) and when it has water ?
How does infrared light behave in both cases?
Also will the plastic body of the container interfere ?
Basically, if we omit the plastic(as it'll have static value), will the intensity of ir light decrease when passing through water(compared to air) ? how much percent ?
